Subject: Re: sha1(md5($pass)

Hi again,

Ok, i compiled the last JUMBO 2 1.7.8, some Algo's results are better compared
to the Erik Version ( 1.7.6 Jumbo 12)

Here some bench's about & compared with the "Erik" version.

Also & concern my request & question about the "Sha 1(md5($pass)" & conform to
your advices by invoking "md5_gen(23)", unfortunately that's don't work with the
last Jumbo2. ( for info i compiled for MAC & x64 one)

Here the error i got :

**************************

new-host-4:run xxx$ ./john --format='md5_gen(23)' mm.txt
Unknown ciphertext format name requested
new-host-4:run xxx$ arch -i386 ./john --format='md5_gen(23)' mm.txt
arch: posix_spawnp: ./john: Bad CPU type in executable

*************************

So, i am going to compiled an new one who are not in "x_64" to get the SSE2.

Anyway, if some of you are interested by bench's, here some cross tests with :

1.7.8 Jumbo 2

&

1.7.6 Jumbo 12 ( from Erik)
