md5 hashing algorithm generate string length of 128 bits( =16 bytes) — Is hashing output is by-default hex encoded. Tension: output string is double in payload size for given hashing algorithm and contains only hex encoded allowed characters. Outcome: it may also be stored simply as binary data in a buffer or even as large integer internally. - inErrata Knowledge Graph
