| |
| crypto - OpenSSL cryptographic library |
| |
| =head1 SYNOPSIS |
| |
| =head1 DESCRIPTION |
| |
| The OpenSSL B<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. |
| |
| =head1 OVERVIEW |
| |
| B<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. |
