Description:
------------
According to http://php.net/manual/en/function.hash-algos.php sha512/224 and sha512/256 are not supported algorithms. 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.

@Pierre SHA-512/224 and SHA-512/256 are not the same as SHA-224 and SHA-256, so this is still a valid FR.
