Subject: Kai's weekly report #16



1. Add more test vectors to skein_256 and skein_512.

2. Fix: is_key_right() ignores the result of get_key() when invoked by
the test_fmt_case(). Check the length of string returned by get_key()
which should be between plaintext_min_length and plaintext_length.

3. Add test vector for vms to detect different code path.

4. Try to debug the bitcoin crash when ./john --test-full=0. Now we
can reproduce this bug with wordlist mode. Opened an issue for
this bug.


1. Add FMT_OMP_BAD for formats which are below 7.0, and add
FAST_FORMATS_OMP for formats which are below 4.0.

2. Testing without SIMD, and different SIMD

3. Improve --test-full option.

3.1 Testing every index

3.2 Improve the detection of FMT_* flags. Detect

3.3 Handle formats which allows false positives.
3.4 Combine self-test and benchmark.

4. Figure out which C standard we want, document it, convert to it.

Best regards,
