It's better on GPU with ~141 Mc/s :)

$ ./john --format=cryptosafe-opencl --session=cryptogpumask_a --mask='?a' \

it will be a veeeeery long run. Obviously I won't be able to brute force 8 \
characters. Keyboard used for initial password input is most likely French (ISO-FR), \
so I would need to add accents too (éèà çÉÈÀÇ etc.) :(

On the CPU side I'm trying other ways: 

$ OMP_NUM_THREADS=10 ./john --wordlist=/usr/local/share/john/rockyou.txt \
--rules=hashcat --max-length=32 --session=crypto2 ../../target.cryptosafe  Using \
default input encoding: UTF-8 Loaded 1 password hash (cryptoSafe [AES-256-CBC])
Will run 10 OpenMP threads

I'll have to be *really* lucky to break this one.
