Evp

Evp evp – 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 […]
