change hash type

Hello everyone,

i am trying to recovery my password from a opensuse system.
i have copy /etc/passwd and /etc/shadow
then attempt the commande unshadown /etc/passwd /etc/shadow > password

and i am trying to find the plain text for the hash.

The problem is that my hash is Blowfish 32 and when i tried Cudahashcat, i only test 280h/s
i would like to know how to increase the speed or how to change Blowfish to md5 or another one

thank you very much for your help.

ps : here a screen capture
i use Cudahashcat 1.20 with a GTX 765M

The GPU is able work faster ( an exemple with another hash type)
