144 crypto \- OpenSSL cryptographic library
146 .IX Header "SYNOPSIS"
148 .IX Header "DESCRIPTION"
149 The OpenSSL \fBcrypto\fR library implements a wide range of cryptographic
150 algorithms used in various Internet standards. The services provided
151 by this library are used by the OpenSSL implementations of \s-1SSL\s0, \s-1TLS\s0
152 and S/MIME, and they have also been used to implement \s-1SSH\s0, OpenPGP, and
153 other cryptographic standards.
155 .IX Header "OVERVIEW"
156 \&\fBlibcrypto\fR consists of a number of sub-libraries that implement the
157 individual algorithms.
159 The functionality includes symmetric encryption, public key
160 cryptography and key agreement, certificate handling, cryptographic
161 hash functions and a cryptographic pseudo-random number generator.
