NAME    [Toc]    [Back]

       crypto - OpenSSL cryptographic library

LIBRARY    [Toc]    [Back]

       libcrypto, -lcrypto

SYNOPSIS    [Toc]    [Back]

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    [Toc]    [Back]

       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 pseudorandom
 number generator.
