They work through the data a chunk at a time and are called block ciphers. It enables the sender of a message to make the message unintelligible to everyone apart from the receiver. Hash functions are considered to be a type of one-way encryption because keys are not shared and the information required to reverse the encryption does not exist in the output. Rather than being identical to the initial data thats been fed to the algorithm, the hashing result is a fixed length value of ones and zeroes, known as a digest, which is always the same size regardless of the size of the original file. For example, s = SIGNATURE (p) = p ^ d % z. The challenge of successfully attacking a cipher is easier if the cipher itself is already flawed. Your password is never retained. Thisform of encryption has been the U.S. government standard as of 2002. AES isused worldwide.
