DDEESSCCRRIIPPTTIIOONN
The OpenSSL ccrryyppttoo library implements a wide range of
cryptographic algorithms used in various Internet stan-
dards. 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.
OOVVEERRVVIIEEWW
lliibbccrryyppttoo 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.
