Subject: Re: Advice on proposal: John the Ripper jumbo robustness
I wrote a patch to calculate the execution time and invoked times of each
function.
The patch is attached. The log file is generated by "$ ./john 7z_fmt", but
it is too
large to attach it.
Below is the analysis of the log file, we can see most of the time is spent
in the
function: 7z_fmt_plug.c:sevenzip_kdf()
