I can't make my video card to search for the password set for my Zip archive. What is the reason?

GPU support for attacking ZIP passwords with classic encryption is restricted. 

It is available just for a brute force attack if you don't use masks. GPU is also not supported for a dictionary based attack.

It is connected with the peculiarities of Zip algorithm with Classic Encryption.

We are planning to improve GPU password recovery compatibility with Zip Classic Encryption in future versions. Subscribe for our news to stay informed.

So, perhaps, you are trying to use an attack that is not supported on video cards.
