Artifact 1f3277f0852b49ce84fbbe408410fb30d205e9f35ef698548b8e72b87598e097:

• File src/OFASN1NumericString.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: 3130) [annotate] [blame] [check-ins using] [more...]
