Question regarding RSA DSA algos

[KT819GM]

I'm sure that somewhere it was already answered just I could not find it. Sorry for that. Question would be - how complex for GPU to add cert file BF for paraphrase search? BF or Dict attack any of them.

edit:
Seems need to forget it. Just checked that I'm talking about 1024bit RSA and 1040 DSA mix. So nothing to say here more - just forget this thread.
