     NAME
          crypto - OpenSSL cryptographic library

     SYNOPSIS
     DESCRIPTION
          The OpenSSL crypto library implements a wide range of
          cryptographic algorithms used in various Internet standards.
          The services provided by this library are used by the
          OpenSSL implementations of SSL, TLS and S/MIME, and they
          have also been used to implement SSH, OpenPGP, and other
          cryptographic standards.

     OVERVIEW
          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.
