Perbandingan Algoritma Kriptografi Hash Sha 256 dan Sha 512 Untuk keamanan sandi

Abstract

Hash algorithms are still in great demand for use in data security but there are still many things that need to be tested Time and security of the hash algorithm. the author has tested the hash-256 algorithm and the hash-512 algorithm from testing both hash algorithms found a very unique comparison, namely the results of the hash-256 algorithm encryption of numeric characters are superior to the results of the hash-512 algorithm encryption for numeric characters when the original plaintext is returned. the conclusion is that the encryption of numeric characters from the hash-256 algorithm is safer to use than the results of the hash-512 algorithm encryption..
