Artifact f6372245cc9b33b3627a357b9d14d0f5cff054556a006544bcdcf239b1fe4f45:

• File src/OFSHA224Or256Hash.h — part of check-in [951f530aee] at 2016-07-24 00:06:30 on branch trunk — Rename OFHash to OFCryptoHash

  OFHash is too generic, as this protocol is for cryptographic hashes. It
  also solves the ambiguity of the +[hash] method (which is now
  +[cryptoHash]), which conflicted with -[hash] on the class itself,
  resulting in classes conforming to OFHash not being able to be used as a
  key in an OFDictionary. (user: js, size: 1013) [annotate] [blame] [check-ins using]
