I would use python for this one, and find a snefru library. Here's the kind of code I'd use:
import rstr, snefru_library
snefru_to_crack = 75b30994e8deafd6a832d3ba295be783e8c62692a4ba4d67fd39a8f2d11745c6 re_string = regex expression for https://www.humblebundle.com/?gift=*N*cyN82SYM*DRb*
while True: random_string = rstr.getrandomstring(re_string) if snefru.get(snefru_to_crack) == random_string: break
print random_string
This code won't run at all - it's just an outline to what I'd do. If you use python, the library rstr
can generate a string from a regex expression.
I'm going to work on a FAQ/Guide to doing things like this, so stay tuned!
