), through the hashing algorithm, transformed into a fixed-length output, the output is the hash value. This conversion is a compression map, that is, the space of the hash value is usually much smaller than the input space, the different inputs may be hashed to the same output, but not from the hash value to uniquely determine the input value. Simply, a function that compresses messages of any length to a message digest of a fixed length. Common algorithms? SHA-1, SHA-256 , MD5, MD2Characteris
