ObjFW  Artifact [7c5227bed5]

Artifact 7c5227bed572c6d2e26f07cf7c4da94b2f2885dc074245cc22e9252cb1248992:

• File tests/OFHMACTests.m — part of check-in [82801897d3] at 2022-03-25 10:22:55 on branch trunk — OFCryptographicHash: Add -[calculate]

  Before, -[digest] would do the final calculation, however, this would
  mean a property modifies state, which is bad. (user: js, size: 5475) [annotate] [blame] [check-ins using] [more...]
