NAME

evp − High-level cryptographic functions

SYNOPSIS

 #include <openssl/evp.h>

DESCRIPTION

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

EVP_Seal... and EVP_Open... provide public key encryption and decryption to implement digital envelopes. 

The EVP_Sign... and EVP_Verify... functions implement digital signatures. 

Symmetric encryption is available with the EVP_Encrypt... functions.  The EVP_Digest... functions provide message digests. 

Algorithms are loaded with OpenSSL_add_all_algorithms().
