The variable output length functions are called eXtensible Output Functions (XOFs). An XOF isn't a cryptographic hash function, though they can be very similar (and can have an identical internal function doing the work). We use different words for Cryptographic Hashes, Password Hashes, XOFs, MACs, and (non-cryptographic) Hashes because they do different things and have different security properties. Misusing the terminology makes reasoning about what is meant difficult. |
