5 evp - high-level cryptographic functions
9 #include <openssl/evp.h>
13 The EVP library provides a high-level interface to cryptographic
16 B<EVP_Seal>I<...> and B<EVP_Open>I<...> provide public key encryption
17 and decryption to implement digital "envelopes".
19 The B<EVP_Sign>I<...> and B<EVP_Verify>I<...> functions implement
22 Symmetric encryption is available with the B<EVP_Encrypt>I<...>
23 functions. The B<EVP_Digest>I<...> functions provide message digests.
25 Algorithms are loaded with OpenSSL_add_all_algorithms(3).
