Description

I would like to fuzz the various hash extraction programs we have, to improve their robustness.

https://github.com/kholia/JohnTheRipper/tree/libFuzzer is a start. It has already found some crashes in keepass2john.c 👍

Research direction

Start with the libFuzzer branch linked in the issue and review the crashes it found in keepass2john.c. Survey the hash extraction programs mentioned in the issue and determine which fuzzing coverage is still missing. Done means the targeted programs have fuzzing support and improved robustness, but the issue does not define a narrower completion criterion.
