Hello, have you tested Bitcrack externally? The card is very old, Bitcrack's OpenCL version has some bugs. Can you provide information by doing an external test (without using bitcrackrandomiser)

Thanks.

Hi, just gave it a try, seems that clBitcrack works in stand-alone:

Can you test like below and verify it works?

$ clBitcrack.exe -b 64 -t 256 -p 256 -d 0 --keyspace 3F94A080000000000:3F94A090000000000 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so 1AYRwmDyowDQLZKhzHmtGNwsD7bUp1qq9A 15JVX6DrCLc1JeFFLu5TmEFNYwz7e2JiBp 16otECJAsiiM54WyX98kkrmDNTEaSzi6fS 

If it works smoothly, I need to investigate the error in the application codes. Thank you for feedback.

As I predicted. An issue with the OpenCL version of Bitcrack. I think there was no such problem in Bitcrack v0.30 version. I'll keep the issue open until I find the OpenCL Version of Bitcrack that works fine. If I find a working OpenCL version, I will publish it as prebuilt and on github.

Problem: "Bitcrack says it has finished scanning and wants to mark the scanned range using proof keys. However, the problem occurs because there is no proof key found."

Thanks for feedback.

[taj1989]

thank you for the investigation and also for your work!

I haven't found a working version yet. I'm closing the issue, I'll research it again when I have free time.
