• File src/OFCryptoHash.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: 2252) [annotate] [blame] [check-ins using]

• File src/OFCryptoHash.h — part of check-in [19f7dc67af] at 2016-07-24 12:14:41 on branch trunk — -[OFCryptoHash digest]: uint8_t -> unsigned char

  While in practice they are usually the same, the C standard says that
  only char does not have any alignment requirements. As (u)int*_t is
  defined to be an integer type of the specified size, it does not mean
  (u)int8_t needs to be char. (user: js, size: 2258) [annotate] [blame] [check-ins using]
