Thanks :)

I was adding the prefix, $dynamic_7$ and I think that was expecting me to enter the long syntax.

If I do not add that prefix to the hash, it becomes easier :)

Hi NeoFlash,

Here what i do for this type of Hashes.

My hashes lists contain :


Salt Séparator is "$", like you allready do

& i run : ./john --format=dynamic_6 hashes.txt

Dynamic_6 & 7 have are quite same i think, the only diff', is the size
of the salt..but Dev can confirm or Un_confirm

Look :

dynamic_6   | md5(md5($p).$s)
dynamic_7   | md5(md5($p).$s)
