Cryptage c++

WebSHA-512 is not an encryption algorithm, it is a cryptographic hash, which is completely different. One library you can use to perform SHA hashes is OpenSSL. Here's an example of computing the raw SHA-512 hash of some data with OpenSSL: #include ... char data [] = "data to hash"; char hash [SHA512_DIGEST_LENGTH]; SHA512 (data ... Web1.
