Is it purely lowercase? Someone gave an example of how to do this with 10 characters a-z 0-9 a few years ago: https://nicholaslyz.com/blog/2021/07/23/cracking-pdf-hashes-with-hashcat/ https://nicholaslyz.com/blog/2021/07/23/cracking-pdf-hashes-... Also, is the password completely random? If it's not, you'd have a much easier time using a large dictionary rather than every possible 10-character word. As in the article, it looks like on a consumer GPU you'd get on the order of 10MH/s, or 10 million hashes per second. I need someone to check my math on this, but 36**10/10_000_000 GPU-seconds (36 characters, optimistically assuming [a-z0-9] lowercase) is about 4000 GPU-days, so out of reach. The A100 attempt from the article only made it about 15x faster, so you'd still need to wait a few months at best. (This is with the assumption you know it's pure lowercase.) Can someone confirm my math on this?
