  11 =head1 DESCRIPTION
  12
  13 The EVP library provides a high-level interface to cryptographic
  14 functions.
  15
  16 B<EVP_Seal>I<...> and B<EVP_Open>I<...> provide public key encryption
  17 and decryption to implement digital "envelopes".
  18
  19 The B<EVP_Sign>I<...> and B<EVP_Verify>I<...> functions implement
  20 digital signatures.
  21
  22 Symmetric encryption is available with the B<EVP_Encrypt>I<...>
  23 functions.  The B<EVP_Digest>I<...> functions provide message digests.
  24
  25 Algorithms are loaded with OpenSSL_add_all_algorithms(3).
