They were initially defined FIPS 180-4 in March 2012: https://www.federalregister.gov/articles/2012/03/06/2012-5400/announcing-approval-of-federal-information-processing-standard-fips-publication-180-4-secure-hash sha224 and sha256 utilize 32-bit integers and process messages in 512-bit chunks. sha384, sha512, sha512/224 and sha512/256 utilize 64-bit integers and process messages in 1024-bit chunks. The only difference between these four algorithms is that they have different initial values for the hash. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71177&edit=1
