=head1 NAME

evp - high-level cryptographic functions

=head1 SYNOPSIS

 #include <openssl/evp.h>

=head1 DESCRIPTION

The EVP library provided a high-level interface to cryptographic
functions.

B<EVP_Seal>I<...> and B<EVP_Open>I<...> provide public key encryption
and decryption to implement digital "envelopes".

The B<EVP_Sign>I<...> and B<EVP_Verify>I<...> functions implement
digital signatures.

Symmetric encryption is available with the B<EVP_Encrypt>I<...>
functions.  The B<EVP_Digest>I<...> functions provide message digests.

Algorithms are loaded with OpenSSL_add_all_algorithms(3).
