NAME

crypto − OpenSSL cryptographic library

SYNOPSIS

TBA

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. 

The libcrypto consists of a number of sublibraries 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.
