=head1 DESCRIPTION
The OpenSSL B<crypto> library implements a wide range of cryptographic
and S/MIME, and they have also been used to implement SSH, OpenPGP, and
other cryptographic standards.
-=head1 OVERVIEW
-
B<libcrypto> consists of a number of sub-libraries that implement the
individual algorithms.
The functionality includes symmetric encryption, public key
cryptography and key agreement, certificate handling, cryptographic
-hash functions and a cryptographic pseudo-random number generator.
