          - Add ERR_load_{COMP,CT,KDF}_strings() to ERR_load_crypto_strings().
          - Avoid strict aliasing violations in BN_nist_mod_*().
          - Do not return X509_V_ERR_UNSPECIFIED from X509_check_ca().
            No return value of X509_check_ca() indicates failure. Application
            code should therefore issue a checked call to X509_check_purpose()
            before calling X509_check_ca().
          - Rewrite and fix X509v3_asid_subset() to avoid segfaults on some
            valid input.
          - Call the ASN1_OP_D2I_PRE callback after ASN1_item_ex_new().
          - Fix d2i_ASN1_OBJECT to advance the *der_in pointer correctly.

          - Do not refuse valid IPv6 addresses in nc(1)'s HTTP CONNECT proxy.
          - Do not reject primes in trial divisions.
          - Error out on negative shifts in BN_{r,l}shift() instead of
            accessing arrays out of bounds.

          - Plug leak in X509V3_add1_i2d().
          - Only print X.509 versions we know about.
          - Avoid signed integer overflow due to unary negation
          - Initialize readbytes in BIO_gets().
          - Plug memory leak in CMS_add_simple_smimecap().
          - Plug memory leak in X509_REQ_print_ex().
          - Check HMAC() return value to avoid a later use of uninitialized.
          - Avoid potential NULL dereference in ssl_set_pkey().
          - Check return values in ssl_print_tmp_key().
          - Switch loop bounds from size_t to int in check_hosts().
          - Avoid division by zero if no connection was made in s_time.c.
          - Check sk_SSL_CIPHER_push() return value
          - Avoid out-of-bounds read in ssl_cipher_process_rulestr().
          - Use LONG_MAX as the limit for ciphers with long based APIs.
        * New features
          - EVP API for HKDF ported from OpenSSL and subsequently cleaned up.
          - The security level API (SSL_{,CTX}_{get,set}_security_level()) is
            now available. Callbacks and ex_data are not supported. Sane
            software will not be using this.
          - Experimental support for the BoringSSL QUIC API.
          - Add initial support for TS ESSCertIDv2 verification.
          - LibreSSL now uses the Baillie-PSW primality test instead of
            Miller-Rabin .

3.5.3 - Reliability fix

        * Fix d2i_ASN1_OBJECT(). A confusion of two CBS resulted in advancing
          the passed *der_in pointer incorrectly. Thanks to Aram Sargsyan for
          reporting the issue and testing the fix.

3.5.2 - Stable release

        * Bug fixes
          - Avoid single byte overread in asn1_parse2().
          - Allow name constraints with a leading dot. From Alex Wilson.
          - Relax a check in x509_constraints_dirname() to allow prefixes.
            From Alex Wilson.
          - Fix NULL dereferences in openssl(1) cms option parsing.
          - Do not zero the computed cofactor on ec_guess_cofactor() success.
          - Bound cofactor in EC_GROUP_set_generator() to reduce the number of
            bogus groups that can be described with nonsensical parameters.
          - Avoid various potential segfaults in EVP_PKEY_CTX_free() in low
            memory conditions. Reported for HMAC by Masaru Masuda.
          - Plug leak in ASN1_TIME_adj_internal().
          - Avoid infinite loop for custom curves of order 1.
            Issue reported by Hanno Boeck, comments by David Benjamin.
          - Avoid an infinite loop on parsing DSA private keys by validating
            that the provided parameters conform to FIPS 186-4.

3.5.1 - Security release

        * A malicious certificate can cause an infinite loop.
          Reported by and fix from Tavis Ormandy and David Benjamin, Google.

3.5.0 - Development release

        * New Features
          - The RFC 3779 API was ported from OpenSSL. Many bugs were fixed,
            regression tests were added and the code was cleaned up.
          - Certificate Transparency was ported from OpenSSL. Many internal
            improvements were made, resulting in cleaner and safer code.
            Regress coverage was added. libssl does not yet make use of it.
        * Portable Improvements
          - Fixed various POSIX compliance and other portability issues
            found by the port to the Sortix operating system.
          - Add libmd as platform specific libraries for Solaris.
            Issue reported from (ihsan <at> opencsw org) on libressl ML.
          - Set IA-64 compiler flag only if it is HP-UX with IA-64.
            Suggested from Larkin Nickle (me <at> larbob org) by libressl ML.
          - Enabled and scheduled Coverity scan.
            Contributed by Ilya Shipitsin (chipitsine <at> gmail com> \ 
on github.
        * Compatibility Changes
          - Most structs that were previously defined in the following headers
            are now opaque as they are in OpenSSL 1.1:
            bio.h, bn.h, comp.h, dh.h, dsa.h, evp.h, hmac.h, ocsp.h, rsa.h,
            x509.h, x509v3.h, x509_vfy.h
          - Switch TLSv1.3 cipher names from AEAD- to OpenSSL's TLS_
            OpenSSL added the TLSv1.3 ciphersuites with "RFC names" instead
            of using something consistent with the previous naming. Various
            test suites expect these names (instead of checking for the much
            more sensible cipher numbers). The old names are still accepted
            as aliases.
          - Subject alternative names and name constraints are now validated
            when they are added to certificates. Various interoperability
            problems with stacks that validate certificates more strictly
            than OpenSSL can be avoided this way.
          - Attempt to opportunistically use the host name for SNI in s_client
        * Bug fixes
          - In some situations, the verifier would discard the error on an
            unvalidated certificate chain. This would happen when the
            verification callback was in use, instructing the verifier to
            continue unconditionally. This could lead to incorrect decisions
            being made in software.
          - Avoid an infinite loop in SSL_shutdown()
          - Fix another return 0 bug in SSL_shutdown()
          - Handle zero byte reads/writes that trigger handshakes in the
            TLSv1.3 stack
          - A long standing memleak in libtls CRL handling was fixed
        * Internal Improvements
          - Cache the SHA-512 hash instead of the SHA-1 hash and cache
            notBefore and notAfter times when X.509 certificates are parsed.
          - The X.509 lookup code has been simplified and cleaned up.

3.4.0 - Development release

        * Add support for OpenSSL 1.1.1 TLSv1.3 APIs.

        * Enable new x509 validator.

        * More details to come, testing is appreciated.

3.3.5 - Security fix

        * A stack overread could occur when checking X.509 name constraints.
          From GoldBinocle on GitHub.

        * Enable X509_V_FLAG_TRUSTED_FIRST by default in the legacy verifier.
          This compensates for the expiry of the DST Root X3 certificate.

3.3.4 - Security fix

        * In LibreSSL, printing a certificate can result in a crash in
          From Ingo Schwarze

        * Ensure GNU-stack is set on ELF platforms when building with CMake to
          enable non-executable stack annotations for the GNU toolchain.
          From Tobias Heider

3.3.3 - Stable release

        * This is the first stable release from the 3.3.x series.
          There are no changes from 3.3.2.

3.3.2 - Development release

        * This release adds support for DTLSv1.2 and continues the rewrite
          of the record layer for the legacy stack. Numerous bugs and
          interoperability issues were fixed in the new verifier. A few bugs
          and incompatibilities remain, so this release uses the old verifier
          by default. The OpenSSL 1.1 TLSv1.3 API is not yet available.

        * Switch finish{,_peer}_md_len from an int to a size_t.

        * Make SSL_get{,_peer}_finished() work when used with TLSv1.3.

        * Use EVP_MD_MAX_MD_SIZE instead of 2 * EVP_MD_MAX_MD_SIZE as size
          for cert_verify_md[], finish_md[] and peer_finish_md[]. The factor 2
          was a historical artefact.

        * Correct the return value type from ERR_peek_error() to a long.

        * Avoid use of uninitialized in ASN1_time_parse() which could happen
          on parsing UTCTime if the caller did not initialise the passed
          struct tm.

        * Destroy the mutex in a tls_config object on tls_config_free().

        * Free alert_data and phh_data in tls13_record_layer_free()
          these could leak if SSL_shutdown() or tls_close() were called
          after closing the underlying socket().

        * Free struct members in tls13_record_layer_free() in their natural
          order for reviewability.

        * Gracefully handle root certificates being both trusted and

        * Handle X509_V_ERR_UNABLE_TO_VERIFY_LEAF_SIGNATURE in the new

        * Use the legacy verifier when building auto chains for TLS.

        * Use consistent names in tls13_{client,server}_finished_{recv,send}().

        * Add tls13_secret_{init,cleanup}() and use them throughout the
          TLSv1.3 code base.

        * Move the read MAC key into the TLSv1.2 record layer.

        * Make tls12_record_layer_free() NULL safe.

        * Search the intermediates only after searching the root certs in the
          new verifier to avoid problems with the legacy callback.

        * Bail out early after finding a single chain in the new verifier, if
          we have been called via the legacy verifier API.

        * Set (invalid and likely incomplete) chain on the xsc on chain build
          failure prior to calling the callback. This is required by various
          callers, including auto chain.

        * Align SSL_get_shared_ciphers() with OpenSSL. This takes into account
          that it never returned server ciphers, so now it will fail when
          called from the client side.

        * Add support for SSL_get_shared_ciphers() with TLSv1.3.

        * Split the record protection from the TLSv1.2 record layer.

        * Clean up sequence number handling in the new TLSv1.2 record layer.

        * Clean up sequence number handling in DTLS.

        * Clean up dtls1_reset_seq_numbers().

        * Factor out code for explicit IV length, block size and MAC length
          from tls12_record_layer_open_record_protected_cipher().

        * Provide record layer overhead for DTLS.

        * Provide functions to determine if TLSv1.2 record protection is

        * Add code to handle change of cipher state in the new TLSv1.2 record

        * Mop up now unused dtls1_build_sequence_numbers() function.

        * Allow setting a keypair on a tls context without specifying the
          private key, and fake it internally in libtls. This removes the
          need for privsep engines like relayd to use bogus keys.

        * Skip the private key check for fake private keys.

        * Move the private key setup from tls_configure_ssl_keypair() to a
          helper function with proper error checking.

        * Change the internal tls_configure_ssl_keypair() function to
          return -1 instead of 1 on failure.

        * Move sequence numbers into the new TLSv1.2 record layer.

        * Move AEAD handling into the new TLSv1.2 record layer.

        * Remove direct assignment of aead_ctx to avoid a leak.

        * Add a number of RPKI OIDs from RFC 6482, 6484, 6493, 8182, 8360,
          draft-ietf-sidrops-rpki-rta, and draft-ietf-opsawg-finding-geofeeds.

        * Fail early in legacy exporter if the master secret is not available
          to avoid a segfault if it is called when the handshake is not

        * Factor out legacy stack version checks.

        * Correct handshake MAC/PRF for various TLSv1.2 cipher suites which
          were originally added with the default handshake MAC and PRF rather
          than the SHA256 handshake MAC and PRF.

        * Absorb ssl3_get_algorithm2() into ssl_get_handshake_evp_md().

        * Use dtls1_record_retrieve_buffered_record() to load buffered
          application data.

        * Enforce read ahead with DTLS.

        * Remove bogus DTLS checks that disabled ECC and OCSP.

        * Sync cert.pem with Mozilla NSS root CAs except "GeoTrust Global \ 

        * Only print the certificate file once on verification failure.

        * Pull in fix for EVP_CipherUpdate() overflow from OpenSSL.

        * Clean up and simplify dtls1_get_cipher().

        * Group HelloVerifyRequest decoding and add missing check for trailing

        * Revise HelloVerifyRequest handling for DTLSv1.2.

        * Handle DTLS1_2_VERSION in various places.

        * Add DTLSv1.2 methods.

        * Make SSL{_CTX,}_get_{min,max}_proto_version() return a version of
          zero if the minimum or maximum has been set to zero to match
          OpenSSL's behavior.

        * Rename the "truncated" label into "decode_err" and \ 
the "f_err"
          label into "fatal_err".

        * Factor out and change some of the legacy client version code.

        * Simplify version checks in the TLSv1.3 client. Ensure that the
          server announced TLSv1.3 and nothing higher and check that the
          legacy_version is set to TLSv1.2 as required by RFC 8446.

        * Fix an off-by-one in x509_verify_set_xsc_chain() to make sure that
          the new validator checks for EXFLAG_CRITICAL in
          x509_vfy_check_chain_extension() for all untrusted certs in the
          chain. Take into account that the root is not necessarily trusted.

        * Avoid passing last and depth to x509_verify_cert_error() on ENOMEM.

        * Rename depth to num_untrusted.

        * Only use TLS versions internally rather than both TLS and DTLS
          versions since the latter are the one's complement of the human
          readable version numbers, which means that newer versions decrease
          in value.

        * Fix two bugs in the legacy verifier that resulted from refactoring
          of X509_verify_cert() for the new verifier: a return value was
          incorrectly treated as boolean, making it insufficient to decide
          whether validation should carry on or not.

        * Identify DTLS based on the version major value.

        * Move handling of cipher/hash based cipher suites into the new record

        * Add tls12_record_protection_unused() and call it from CCS functions.

        * Move key/IV length checks closer to usage sites. Also add explicit
          checks against EVP_CIPHER_{iv,key}_length().

        * Replace two handrolled tls12_record_protection_engaged().

        * Improve internal version handling: add handshake fields for our
          minimum version, our maximum version and the TLS version negotiated
          during the handshake. Convert most of the internal code to use these
          version fields.

        * Guard against future internal use of TLS1_get_{client,}_version()

        * Remove the internal ssl_downgrade_max_version() function which is no
          longer needed.

        * Fix checks for memory caps of constraints names. There are internal
          caps on the number of name constraints and other names, that the new
          name constraints code allocates per cert chain. These limits were
          checked too late, making them only partially effective.

        * Use EXFLAG_INVALID to handle out of memory and parse errors in

        * Add support for DTLSv1.2 version handling.

        * Enable DTLSv1.2 support.

        * Add DTLSv1.2 support to openssl s_client/s_server.

        * Remove no longer needed read ahead workarounds in the s_client and

        * Fix a copy-paste error - skid was confused with an akid when
          checking for EXFLAG_INVALID. This broke OCSP validation with
          certain mirrors.

        * Make supported protocols and options for DHE params more prominent
          in tls_config_set_protocols.3.

        * Avoid a use-after-scope in tls13_cert_add().

        * Split TLSv1.3 record protection from record layer.

        * Move the TLSv1.3 handshake struct inside the shared handshake

        * Fully initialize rrec in tls12_record_layer_open_record_protected()
          to avoid confusing some static analyzers.

        * Use tls_set_errorx() on OCSP_basic_verify() failure since the latter
          does not set errno.

        * Convert openssl(1) x509 to new option handling and do the usual
          clean up that goes along with it.

        * Add SSL_HANDSHAKE_TLS12 for TLSv1.2 specific handshake data.

        * Rename new_cipher to cipher to align naming with keyblock or other
          parts of the handshake data.

        * Avoid mangled output in BIO_debug_callback().

        * Fix client initiated renegotiation by replacing use of s->internal-type
          with s->server.

        * Move the TLSv1.2 record number increment into the new record layer.

        * Move finished and peer finished into the handshake struct.

        * Avoid transcript initialization when sending a TLS HelloRequest,
          fixing server initiated renegotiation.

        * Remove pointless assignment in SSL_get0_alpn_selected().

        * Provide EVP_PKEY_new_CMAC_KEY(3).

        * Add missing prototype for d2i_DSAPrivateKey_fp(3) to x509.h.

        * Add DTLSv1.2 to openssl(1) s_server and s_client protocol message

        * Avoid leaking param->name in x509_verify_param_zero().

        * Avoid a leak in an error path in openssl(1) x509.

        * Add some error checking to openssl(1) x509.

        * When sending an alert in TLSv1.3, only set its error code when no
          other error was set previously. Certain clients rely on specific
          SSL_R_ error codes to identify that they are dealing with a self
          signed cert.

        * Switch to the legacy verifier for the stable release.

        * Provide SSL_use_certificate_chain_file(3).

        * Provide various DTLSv1.2 specific functions and defines.

        * Document meaning of '*' in the genrsa output.

        * Updated documentation for SSL_get_shared_ciphers(3).

        * Add documentation for SSL_get_finished(3).

        * Document EVP_PKEY_new_CMAC_key(3)

        * Update SSL_get_version.3 manual for DTLSv.1.2 support.

        * Added '--enable-libtls-only' build option, which builds and installs a
          statically-linked libtls, skipping libcrypto and libssl. This is useful
          for systems that ship with OpenSSL but wish to also package libtls.

3.3.1 - Security fix

        * Malformed ASN.1 in a certificate revocation list or a timestamp
          response token can lead to a NULL pointer dereference.

        Bug fixes

          verifying ECDSA signatures with unchecked public keys.

        * Fix SSL_is_server() to behave as documented by re-introducing the
          client-specific methods.

        * Avoid undefined behavior due to memcpy(NULL, NULL, 0).

        * Mark a few more internal static tables const.

3.3.0 - Development release

        * Make openssl(1) s_server ignore -4 and -6 for compatibility with

        * Further cleanup of the DTLS record handling.

        * Continue the replacement of the TLSv1.2 record layer by
          reimplementing the read side of the TLSv1.2 record handling.

        * Replace DTLSv1_enc_data() with TLSv1_1_enc_data().

        * Merge d1_{clnt,srvr}.c into ssl_{clnt,srvr}.c.

        * When switching from the TLSv1.3 stack to the legacy stack include
          a TLS record header. This is necessary if there is more than one
          handshake message in the TLS plaintext record.

        * Set SO_REUSEADDR on the server socket in the openssl(1) ocsp

        * Fix resource handling on error in OCSP_request_add0_id().

        * Add const to ssl_ciphers and tls1[23]_sigalgs* to push them into
          .data.rel.ro and .rodata, respectively.

        * Add a const qualifier to srtp_known_profiles.

        * Simplify TLS method by removing the client and server specific
          methods internally.

        * Avoid casting away const in ssl_ctx_make_profiles().

        * Make sure there is enough room for stashing the handshake message
          when switching to the legacy TLS stack.

        * Avoid explicitly conditioning an assert on DTLS1_VERSION to make
          the assert work for newer DTLS versions.


        * Send a host header with OCSP queries to make openssl(1) ocsp
          work with some widely used OCSP responders.

        * Fix a memory leak in the openssl(1) s_client.

        * Add a flag to mark DTLS methods as DTLS to have an easy way to
          recognize DTLS methods that avoids inspecting the version number.

        * Implement SSL_is_dtls() and use it internally in place of the
          SSL_IS_DTLS macro.

        * Unbreak DTLS retransmissions for flights that include a CCS.

        * Add ability to ocspcheck(8) to parse a port in the specified
          OCSP URL.

        * Refactor and clean up ocspcheck(8) and add regression tests.

        * If x509_verify() fails, ensure that the error is set on both
          the x509_verify_ctx() and its store context to make some failures
          visible from SSL_get_verify_result().

        * Use the X509_STORE_CTX get_issuer() callback from the new X.509
          verifier to fix hashed certificate directories.

        * Only check BIO_should_read() on read and BIO_should_write() on
          write.  Previously, BIO_should_write() was also checked after read
          and BIO_should_read() after write which could cause stalls in
          software that uses the same BIO for read and write.

        * In openssl(1) verify, also check for error on the store context
          since the return value of X509_verify_cert() is unreliable in
          presence of a callback that returns 1 too often.

        * Update getentropy on Windows to use Cryptography Next Generation
          (CNG). wincrypt is deprecated and no longer works with newer Windows
          environments, such as in Windows Store apps.

        * Implement auto chain for the TLSv1.3 server since some software
          relies on this.

        * Handle additional certificate error cases in the new X.509 verifier.
          Keep track of the errors encountered if a verify callback tells the
          verifier to continue and report them back via the error on the store
          context. This mimics the behavior of the old verifier that would
          persist the first error encountered while building the chain.

        * Report specific failures for "self signed certificates" in a way
          compatible with the old verifier since software relies on the
          error code.

        * Implement key exporter for TLSv1.3.

        * Plug a large memory leak in the new verifier caused by calling
          X509_policy_check() repeatedly.

        * Avoid leaking memory in x509_verify_chain_dup().

        * Various documentation improvements, particularly around TLS methods.

3.2.3 - Security fix

        * Malformed ASN.1 in a certificate revocation list or a timestamp
          response token can lead to a NULL pointer dereference.

3.2.2 - Stable release

        * This is the first stable release with the new TLSv1.3
          implementation enabled by default for both client and server. The
          OpenSSL 1.1 TLSv1.3 API is not yet available and will be provided
          in an upcoming release.

        * New X509 certificate chain validator that correctly handles
          multiple paths through intermediate certificates. Loosely based on

        * Make SSL_CTX_get_ciphers(NULL) return NULL rather than crash.

        * Send alert on ssl_get_prev_session() failure.

        * Zero out variable on the stack to avoid leaving garbage in the tail
          of short session IDs.

        * Move state initialization from SSL_clear() to ssl3_clear() to ensure
          that it gets correctly reinitialized across a SSL_set_ssl_method()

        * Avoid an out-of-bounds write in BN_rand().

        * Fix numerous leaks in the UI_dup_* functions. Simplify and tidy up
          the code in ui_lib.c.

        * Correctly track selected ALPN length to avoid a potential segmentation
          fault with SSL_get0_alpn_selected() when alpn_selected is NULL.

          __STRICT_ALIGNMENT define.

        * Simplify SSL method lookups.

        * Clean up and simplify SSL_get_ciphers(), SSL_set_session(),
          SSL_set_ssl_method() and several internal functions.

        * Correctly handle ssl_cert_dup() failure in SSL_set_SSL_CTX().

        * Refactor dtls1_new(), dtls1_hm_fragment_new(),
          dtls1_drain_fragments(), dtls1_clear_queues().

        * Copy the session ID directly in ssl_get_prev_session() instead of
          handing it through several functions for copying.

        * Clean up and refactor ssl_get_prev_session(); simplify
          tls_decrypt_ticket() and tls1_process_ticket() exit paths.

        * Avoid memset() before memcpy() in CBS_add_bytes().

        * Rewrite X509_INFO_{new,free}() more idiomatically.

        * Remove unnecessary zeroing after recallocarray() in

          in a TLSv1.3 record.

3.2.0 - Development release

        * Enable TLS 1.3 server side in addition to client by default.
          With this change TLS 1.3 is handled entirely on the new stack
          and state machine, with fallback to the legacy stack and
          state machine for older versions. Note that the OpenSSL TLS 1.3
          API is not yet visible/available.

        * Improve length checks in the TLS 1.3 record layer and provide
          appropriate alerts for violations of record layer limits.

        * Enforce that SNI hostnames received by the TLS server are correctly

          switching from the new to legacy stacks.

        * Support TLS 1.3 options in the openssl(1) command.

        * Many alert cleanups in TLS 1.3 to provide expected alerts in failure

        * Modify "openssl x509" to display invalid certificate times as
          invalid, and correctly deal with the failing return case from
          X509_cmp_time so that a certificate with an invalid NotAfter does
          not appear valid.

        * Support sending dummy change_cipher_spec records for TLS 1.3 middlebox

        * Ensure only PSS signatures are used with RSA in TLS 1.3.

          method in its legacy_compression_methods.

        * Correct use of sockaddr_storage instead of sockaddr in openssl(1)
          s_client, which could lead to using 14 bytes of stack garbage instead
          of an IPv6 address in DTLS mode.

        * Use non-expired certificates first when building a certificate chain.

3.1.5 - Security fix

        * Malformed ASN.1 in a certificate revocation list or a timestamp
          response token can lead to a NULL pointer dereference.

        * Improve client certificate selection to allow EC certificates
          instead of only RSA certificates.

        * Do not error out if a TLSv1.3 server requests an OCSP response as
          part of a certificate request.

        * Fix SSL_shutdown behavior to match the legacy stack.  The previous
          behaviour could cause a hang.

        * Fix a memory leak and add a missing error check in the handling of
          the key update message.

        * Fix a memory leak in tls13_record_layer_set_traffic_key.

        * Avoid calling freezero with a negative size if a server sends a
          malformed plaintext of all zeroes.

        * Ensure that only PSS may be used with RSA in TLSv1.3 in order
          to avoid using PKCS1-based signatures.

        * Add the P-521 curve to the list of curves supported by default
          in the client.

3.1.3 - Bug fix

        * libcrypto may fail to build a valid certificate chain due to
          expired untrusted issuer certificates.

3.1.2 - Bug fix

        * A TLS client with peer verification disabled may crash when
          contacting a server that sends an empty certificate list.

3.1.1 - Stable release

        * Improved cipher suite handling to automatically include TLSv1.3
          cipher suites when they are not explicitly referred to in the
          cipher string.

        * Improved handling of TLSv1.3 HelloRetryRequests, simplifying
          state transitions and ensuring that the legacy session identifer
          retains the same value across the handshake.

        * Provided TLSv1.3 cipher suite aliases to match the names used
          in RFC 8446.

        * Improved TLSv1.3 client key share handling to allow the use of
          any groups in our configured NID list.

        * Fixed printing the serialNumber with X509_print_ex() fall back to
          the colon separated hex bytes in case greater than int value.

        * Fix to show TLSv1.3 extension types with openssl(1) -tlsextdebug.

        * Improved portable builds to support the use of static MSVC runtimes.

        * Fixed portable builds to avoid exporting a sleep() symbol.

3.1.0 - Development release

        * Completed initial TLS 1.3 implementation with a completely new state
          machine and record layer. TLS 1.3 is now enabled by default for the
          client side, with the server side to be enabled in a future release.
          Note that the OpenSSL TLS 1.3 API is not yet visible/available.

        * Many more code cleanups, fixes, and improvements to memory handling
          and protocol parsing.

        * Added RSA-PSS and RSA-OAEP methods from OpenSSL 1.1.1.

        * Ported Cryptographic Message Syntax (CMS) implementation from OpenSSL

          from OpenSSL 1.1.1.

        * Added many new additional crypto test vectors.

        * Adjusted EVP_chacha20()'s behavior to match OpenSSL's semantics.

        * Default CA bundle location is now configurable in portable builds.

        * Added cms subcommand to openssl(1).

        * Added -addext option to openssl(1) req subcommand.

3.0.2 - Stable release

        * Use a valid curve when constructing an EC_KEY that looks like X25519.
          The recent EC group cofactor change results in stricter validation,
          which causes the EC_GROUP_set_generator() call to fail.
          Issue reported and fix tested by rsadowski@

        * Fixed a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey.

3.0.1 - Development release

        * Ported Billy Brumley's fix for CVE-2019-1547 in OpenSSL 1.1.1. If a NULL
          or zero cofactor is passed to EC_GROUP_set_generator(), try to compute
          it using Hasse's bound. This works as long as the cofactor is small

        * Fixed a memory leak in error paths for eckey_type2param().

          description in openssl(1) manual.

        * A plethora of small fixes due to regular oss-fuzz testing.

        * Various side channels in DSA and ECDSA were addressed.  These are some of
          the many issues found in an extensive systematic analysis of bignum usage
          by Samuel Weiser, David Schrammel et al.

        * Enabled openssl(1) speed subcommand on Windows platform.

        * Enabled performance optimizations when building with Visual Studio on \

        * Fixed warnings about clock_gettime on Windows Visual Studio builds.

        * Fixed CMake builds on systems where getpagesize is defined as an
          inline function.

        * CRYPTO_LOCK is now automatically initialized, with the legacy
          callbacks stubbed for compatibility.

        * Added the SM3 hash function from the Chinese standard GB/T 32905-2016.

        * Added more OPENSSL_NO_* macros for compatibility with OpenSSL.

        * Added extensive interoperability tests between LibreSSL and OpenSSL
          1.0 and 1.1.

        * Added additional Wycheproof tests and related bug fixes.

        * Simplified sigalgs option processing and handshake signing algorithm

        * Added support for assembly optimizations on 32-bit ARM ELF targets.

        * Improved protection against timing side channels in ECDSA signature

        * Coordinate blinding was added to some elliptic curves. This is the
          last bit of the work by Brumley et al. to protect against the

        * Fixed memory leak in nc(1)

2.8.1 - Test and compatibility improvements

        * Added Wycheproof support for ECDH, RSASSA-PSS, AES-GCM,
          AES-CMAC, AES-CCM, AES-CBC-PKCS5, DSA, ChaCha20-Poly1305, ECDSA, and
          X25519 test vectors. Applied appropriate fixes for errors uncovered
          by tests.

        * Simplified key exchange signature generation and verification.

        * Fixed a one-byte buffer overrun in callers of EVP_read_pw_string

        * Converted more code paths to use CBB/CBS. All handshake messages are
          now created by CBB.

        * Fixed various memory leaks found by Coverity.

        * Simplified session ticket parsing and handling, inspired by

        * Modified signature of CRYPTO_mem_leaks_* to return -1. This function
          is a no-op in LibreSSL, so this function returns an error to not
          indicate the (non-)existence of memory leaks.

        * SSL_copy_session_id, PEM_Sign, EVP_EncodeUpdate, BIO_set_cipher,
          X509_OBJECT_up_ref_count now return an int for error handling,
          matching OpenSSL.

        * Converted a number of #defines into proper functions, matching
          OpenSSL's ABI.

        * Added X509_get0_serialNumber from OpenSSL.

        * Removed EVP_PKEY2PKCS8_broken and PKCS8_set_broken, while adding
          PKCS8_pkey_add1_attr_by_NID and PKCS8_pkey_get0_attrs, matching

        * Removed broken pkcs8 formats from openssl(1).

        * Converted more functions in public API to use const arguments.

        * Stopped handing AES-GCM in ssl_cipher_get_evp, since they use the
          EVP_AEAD interface.

        * Stopped using composite EVP_CIPHER AEADs.

        * Added timing-safe compares for checking results of signature
          verification. There are no known attacks, this is just inexpensive

        * Correctly clear the current cipher state, when changing cipher state.
          This fixed an issue where renegotiation of cipher suites would fail
          when switched from AEAD to non-AEAD or vice-versa.
          Issue reported by Bernard Spil.

        * Added more cipher tests to appstest.sh, including all TLSv1.2

        * Added RSA_meth_get_finish() RSA_meth_set1_name() from OpenSSL.

        * Added new EVP_CIPHER_CTX_(get|set)_iv() API that allows the IV to be
          retrieved and set with appropriate validation.

2.8.0 - Bug fixes, security, and compatibility improvements

        * Extensive documentation updates and additional API history.

        * Fixed a pair of 20+ year-old bugs in X509_NAME_add_entry

        * Tighten up checks for various X509_VERIFY_PARAM functions,
          'poisoning' parameters so that an unverified certificate cannot be
          used if it fails verification.

        * Fixed a potential memory leak on failure in ASN1_item_digest

        * Fixed a potential memory alignment crash in asn1_item_combine_free

        * Removed unused SSL3_FLAGS_DELAY_CLIENT_FINISHED and
          SSL3_FLAGS_POP_BUFFER flags in write path, simplifying IO paths.

        * Removed SSL_OP_TLS_ROLLBACK_BUG buggy client workarounds.

        * Made ENGINE_finish and ENGINE_free succeed on NULL and simplify callers
          and matching OpenSSL behavior, rewrote ENGINE_* documentation.

        * Added const annotations to many existing APIs from OpenSSL, making
          interoperability easier for downstream applications.

        * Fixed small timing side-channels in ecdsa_sign_setup and

        * Documented security pitfalls with BN_FLG_CONSTTIME and constant-time
          operation of BN_* functions.

        * Updated BN_clear to use explicit_bzero.

        * Added a missing bounds check in c2i_ASN1_BIT_STRING.

        * More CBS conversions, including simplifications to RSA key exchange,
          and converted code to use dedicated buffers for secrets.

        * Removed three remaining single DES cipher suites.

        * Fixed a potential leak/incorrect return value in DSA signature

        * Added a blinding value when generating DSA and ECDSA signatures, in
          order to reduce the possibility of a side-channel attack leaking the
          private key.

        * Added ECC constant time scalar multiplication support.
          From Billy Brumley and his team at Tampere University of Technology.

        * Revised the implementation of RSASSA-PKCS1-v1_5 to match the
          specification in RFC 8017. Based on an OpenSSL commit by David

        * Cleaned up BN_* implementations following changes made in OpenSSL by
          Davide Galassi and others.
