Hashcat RTX 3080 Performance issues (Windows) - xcookes - 03-18-2022
Hello Everyone,
I'm experimenting with hashcat (v6.2.5) on Windows cracking “bcrypt $2*$, Blowfish (Unix)” hashes, but I feel like my hashrate is really slow on RTX 3080.
Is this hashrate correct for this GPU?
Code:
hashcat-6.2.5>hashcat.exe -m 3200 hash.txt rockyou.txt -w 3 -a 0 -O

That is correct. In fact, that's a little faster than i would have expected. Bcrypt is built to be extremely difficult to crack and it does a really god job of it. There's nothing you can do to make it go any faster on that hardware.

Thank you for your response, thats good to hear. The GPU seems quiter than it usually is under load, but I guess thats due to the low memory usage of this type of attack.
