Better performance with multi threading?

[[RTS]BN+VS*]

Hey,

I'm creating a password hash recovery tool that uses brute force. I have the brute force algorithm run in a background worker. It all works, but some similar apps I tried out have performance ~100x bigger then my app. (mine does 50k keys/second, some others do 5m keys/second or more.)

I realize this is partly caused by using a .Net language, but I suspect there are ways to significantly speed up the brute force. A lot of ppl say I should use multi threading, but how is this done in practice? Splitting up the passwords to check would slow down my app I think.

Can anyone help me out on how to improve performance?

Thnx in advance

Well for multithreading you can simply use the BackgroundWorker for this, any code in it's DoWork event will run on a separate thread.

As for the splitting of the passwords to branch to multiple threads, that depends on how you're generating the passwords in the first place I guess.
