RE: precompute bcrypt hashes - f1l1b0x - 02-01-2020

Hi

I cant do it, I dont have the skills to do it. But thanks a ton for the recommendation this is most likely saving me a ton of time.

If someone wants to help me with it. Happy to send you more about the project in a dm.

Thanks

Do you see a way to do it without the need of a modified kernel?

Thanks

as said, for the basic testing and checking the (hexadecimal) digest, you could just add a printf ():
