Artifact fe525c2cd3e15f6d9e5e1417223163abd564a92f09b6670ec78035297cbf1d67:

• File src/OFASN1UTF8String.m — part of check-in [aeb403a1ed] at 2020-10-10 14:27:37 on branch trunk — OFObject: Change type of -[hash] to unsigned long

  The internal hash is still 32 bit in most places, but this way, it is at
  least not baked into the API and ABI and can be upgraded later, should
  that ever be necessary. (user: js, size: 2655) [annotate] [blame] [check-ins using] [more...]
