I have added support for cracking MySQL network authentication hashes
to JtR. Use latest code from

✗ ../run/john -fo:mysqlna -t
Benchmarking: MySQL Network Authentication SHA1 [32/64]... DONE
Raw:	1492K c/s real, 1492K c/s virtual

However, I could not find a open-source software for obtaining
"challenge + hash" from a network capture. I had to use Cain & Abel.

Input Format: $mysqlna$challenge*hash
