@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.

They are, see
http://php.net/manual/en/function.hash-algos.php
[4] => sha224
[5] => sha256
[6] => sha384
[7] => sha512

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.
