evp(3)evp(3)NAMEevp - High-level cryptographic functions
SYNOPSIS
#include <openssl/evp.h>
DESCRIPTION
The EVP library provides a high-level interface to cryptographic func‐
tions.
EVP_Seal... and EVP_Open... provide public key encryption and decryp‐
tion to implement digital envelopes.
The EVP_Sign... and EVP_Verify... functions implement digital signa‐
tures.
Symmetric encryption is available with the EVP_Encrypt... functions.
The EVP_Digest... functions provide message digests.
Algorithms are loaded with OpenSSL_add_all_algorithms().
