In cryptography, MD5 (Message Digest version 5) and SHA (Secure Hash Algorithm) are two well-known message digest algorithms.They are also referred as cryptographic hash functions, which take arbitrary-sized data as input (message) and produce a fixed-length hash value. SHA (Secure Hash Algorithm) je rozšířená hašovací funkce, která vytváří ze vstupních dat výstup (otisk) fixní délky.Otisk je též označován jako miniatura, kontrolní součet (v zásadě nesprávné označení), fingerprint, hash (česky někdy psán i jako haš). Características del algoritmo SHA-256. Un algoritmo hash funciona en una sola dirección: esto quiere decir que de cualquier contenido podemos generar su hash (su “huella dáctilar digital”) pero de un hash no hay forma de generar el contenido asociado a él, salvo probando al azar hasta dar con el contenido. Sep 27, 2018 · SHA-224 and SHA-384 are truncated versions of SHA-256 and SHA-512 respectively, computed with different initial values.
