=head1 NAME

crypto - OpenSSL cryptographic library

=head1 SYNOPSIS

=head1 DESCRIPTION

The OpenSSL B<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.

=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.
