As @vjudeu said, you used un-optimized tool. You should use optimized tool such as hashcat. Even on single core VPS, i managed to get ~5000 kH/s.
Can you walk me through this (ELI5 style)? Say I have
pbies's list of 200 brainwallets, and I want to use hashcat to get the associated Bitcoin addresses.
I'm feeling like a n00b here, hashcat has too many options.Once I've figured out the above, I can start on this: the input-file with passwords I'd like to check is
444 GB and has 40 billion entries.
I have a (dedicated) server at my disposal with:
Intel(R) Xeon(R) CPU E3-1270 V2 @ 3.50GHz
130 GB available diskspace (hdd)
16 GB RAM
I think you misunderstood what i said. What i meant is
speed of SHA-256 hashing. AFAIK Hashcat doesn't have option to brute-force brainwallet.
