A custom-named GenKey function uses CryptGenRandom(), then manually initializes a SHA-512 hash with corresponding constants and effects some permutation to encrypt using randomly-generated keys. WebRandom Numbers are a cryptographic primitive and cornerstone to nearly all cryptographic systems. They are used in almost all areas of cryptography, from key agreement and transport to session keys for bulk encryption. A quality source of random bits and proper use of OpenSSL APIs will help ensure your program is cryptographically sound.
