[...] > These are the 68 formats where the max. password length in bytes differs: I'm sure more of them should have their max length increased in non-SIMD builds - in fact, you've already submitted a fix for one of those: https://github.com/magnumripper/JohnTheRipper/pull/2530 In particular, perhaps Rob's mentioned Kerberos TGS format should be one of those, too? In fact, even if the reported max lengths are not increased, perhaps those 81's (3*27) are for real (for ASCII chars) in that rebuild (unlike they are in SIMD builds, where the actual limit is 27 to 81 input bytes depending on what Unicode chars those are, as magnum explained)?
