hashcat Forum

Hi, I have been using cudaHashcat to crack some PBKDF2 and bcrypt passwords but when I tried to crack scrypt password though I was able to crack the example scrypt hash on https://hashcat.net/wiki/doku.php?id=example_hashes, I get the cuModuleLoad() 301 error when I try to crack the hashes I generated

command and result:

>cudaHashcat64.exe -m 8900 --weak-hash-threshold=0 --potfile-disable --outfile=scrypt_cracked.txt SCR

ERROR: cuModuleLoad() 301

301 usually means you unpacked the archive wrong, but since you're able to crack other formats, not sure what's up. I would suggest using beta instead though.

Is it possible that the issue is because of the work factor, 4096 because I am able to crack scrypt hashes with 104 as the work factor. But, it doesn't makes sense for this error to show up

Well 301 means "file not found" so it's tell you it's not able to find the kernel file. But it's strange that it would be intermittent like that.
