Cryptographic hash rules

WebA cryptographic hash function is a hash function which takes an input (or 'message') and returns a fixed-size string of bytes. The string is called the 'hash value', 'message digest', … WebJul 22, 2024 · A popular hash function is SHA-256. Symmetric Key cryptography: This is also known as Symmetric Encryption. Suppose a message is encrypted using a key. The message is now converted to ciphertext which is readable but has no meaning. The same key is used to decrypt the message. A key is a variable used to encrypt or decrypt a text.
