EVP(3)                       OpenSSL                       EVP(3)


     evp - high-level cryptographic functions


      #include <openssl/evp.h>


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

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

     The EVP_Sign... and EVP_Verify... functions implement digi-
     tal signatures.

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

     Algorithms are loaded with OpenSSL_add_all_algorithms(3).

     All the symmetric algorithms (ciphers) and digests can be
     replaced by ENGINE modules providing alternative implementa-
     tions. If ENGINE implementations of ciphers or digests are
     registered as defaults, then the various EVP functions will
     automatically use those implementations automatically in
     preference to built in software implementations. For more
     information, consult the engine(3) man page.
