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.
