"""Public-key encryption and signature algorithms.

Public-key encryption uses two different keys, one for encryption and
one for decryption.  The encryption key can be made public, and the
decryption key is kept private.  Many public-key algorithms can also
be used to sign messages, and some can *only* be used for signatures.
