dhbitty is a small public key encryption program written in C. It
uses elliptic curve Diffie-Hellman in the form of Curve25519 to
establish a shared secret between two users, and uses that secret to
symmetrically encrypt and authenticate messages.

There are no private key files; only passphrases. Never lose that
pesky thing again.

Both the sender and the receiver can decrypt a message. In fact,
there is no distinction between sender and receiver. Both passphrases
must be strong.

There is no signing. A similarly useful form of authentication occurs
using only DH. dhbitty attempts to be as simple as possible. It is
not optimized, but achieves a comfortable speed for most uses. It
does not use floating point numbers, or integers longer than 32 bits.
It does not contain more algorithms than are needed.
