Before proceeding, I want to check if it's practical to devote any time to cracking this password.
If cracking time = keyspace / hashrate
keyspace = 95^12 = 5.403600877×10²³
hashrate = hashing function / hardware power [Bitcoin's wallet.dat function / GTX 1070]
4508 hashes per sec for Bitcoin wallet.dat, according to hashcat docs
~3000 hashes per second for NVDA GTX 1070, according to my tests
5.403600877×10²³ / ~1.5 = 3.6024×10²³ seconds ... does that sound correct?
If so, that leaves me with a cracking time of 1.1423×10¹⁶ years, with 1x GPU. Even with my GPU farm it sounds like this is a lost cause; do I have any reason to be more optimistic?
