.IX Header "DESCRIPTION"
The OpenSSL \fBcrypto\fR 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 \s-1SSL\s0, \s-1TLS\s0
and S/MIME, and they have also been used to implement \s-1SSH\s0, OpenPGP, and
other cryptographic standards.
.SH "OVERVIEW"
.IX Header "OVERVIEW"
\&\fBlibcrypto\fR consists of a number of sub-libraries that implement the
individual algorithms.
.PP
The functionality includes symmetric encryption, public key
cryptography and key agreement, certificate handling, cryptographic
hash functions and a cryptographic pseudo-random number generator.
