Log Message:
17.1.0:

Backward-incompatible changes:
- Removed the deprecated OpenSSL.rand.egd() function.
  Applications should prefer os.urandom() for random number generation.
- Removed the deprecated default digest argument to OpenSSL.crypto.CRL.export().
  Callers must now always pass an explicit digest.
- Fixed a bug with ASN1_TIME casting in X509.set_notBefore(),
  X509.set_notAfter(), Revoked.set_rev_date(), Revoked.set_nextUpdate(),
  and Revoked.set_lastUpdate(). You must now pass times in the form
  YYYYMMDDhhmmssZ. YYYYMMDDhhmmss+hhmm and YYYYMMDDhhmmss-hhmm
  will no longer work.

Deprecations:
- Deprecated the legacy "Type" aliases: ContextType, ConnectionType, \ 
PKeyType, X509NameType, X509ExtensionType, X509ReqType, X509Type, X509StoreType, \ 
CRLType, PKCS7Type, PKCS12Type, NetscapeSPKIType.
  The names without the "Type"-suffix should be used instead.

Changes:
- Added OpenSSL.crypto.X509.from_cryptography() and \ 
OpenSSL.crypto.X509.to_cryptography() for converting X.509 certificate to and \ 
from pyca/cryptography objects.
- Added OpenSSL.crypto.X509Req.from_cryptography(), \ 
OpenSSL.crypto.X509Req.to_cryptography(), \ 
OpenSSL.crypto.CRL.from_cryptography(), and OpenSSL.crypto.CRL.to_cryptography() \ 
for converting X.509 CSRs and CRLs to and from pyca/cryptography objects.
- Added OpenSSL.debug that allows to get an overview of used library versions \ 
(including linked OpenSSL) and other useful runtime information using python -m \ 
OpenSSL.debug.
- Added a fallback path to Context.set_default_verify_paths() to accommodate the \ 
upcoming release of cryptography manylinux1 wheels.
