|
|
|
The EVP library provides a high-level interface to cryptographic
|
2000-09-23 07:16:17 +00:00
|
|
|
functions.
|
|
|
|
|
|
|
|
|
|
B<EVP_Seal>I<...> and B<EVP_Open>I<...> provide public key encryption
|
|
|
|
|
and decryption to implement digital "envelopes".
|
|
|
|
|
|
|
|
|
|
The B<EVP_Sign>I<...> and B<EVP_Verify>I<...> functions implement
|
|
|
|
|
digital signatures.
|
|
|
|
|
|
|
|
|
|
Symmetric encryption is available with the B<EVP_Encrypt>I<...>
|
|
|
|
|
functions. The B<EVP_Digest>I<...> functions provide message digests.
|
|
|
|
|
|
|
|
|
|
Algorithms are loaded with OpenSSL_add_all_algorithms(3).
