   9 =head1 DESCRIPTION
  10
  11 The OpenSSL B<crypto> library implements a wide range of cryptographic
  12 algorithms used in various Internet standards. The services provided
  13 by this library are used by the OpenSSL implementations of SSL, TLS
  14 and S/MIME, and they have also been used to implement SSH, OpenPGP, and
  15 other cryptographic standards.

  17 =head1 OVERVIEW
  18
  19 B<libcrypto> consists of a number of sub-libraries that implement the
  20 individual algorithms.
  21
  22 The functionality includes symmetric encryption, public key
  23 cryptography and key agreement, certificate handling, cryptographic
  24 hash functions and a cryptographic pseudo-random number generator.
