crypto(3) OpenSSL crypto(3)NAMEcrypto - OpenSSL cryptographic library
SYNOPSISDESCRIPTION
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.
