NAME    [Toc]    [Back]

       evp - High-level cryptographic functions

SYNOPSIS    [Toc]    [Back]

        #include <openssl/evp.h>

DESCRIPTION    [Toc]    [Back]

       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().
