DES Unix (descrypt) crack hash not working ! - islam.h7 - 09-04-2024
I wanted to decrypt some DES Unix hashes mod 1500 , and every time hashcat tells me Exhausted as it doesnt find a crack from the wordlist , so i hashed a string that is already in the wordlist by python crypt module
==> "password" ===> XYGpusIMIT/IM
and i tried the command on it and the same issue occurred even though its already in the wordlist hashcat didnt decrypt it , this is the command :
Code:
.\hashcat.exe -m 1500 -a 0 -o cracked.txt ..\s.txt ..\10-million-password-list-top-1000000.txtand this the output :
Code:
hashcat (v6.2.6) starting
hiprtcCompileProgram is missing from HIPRTC shared library.

Try only nvidia gpu.

How long is your searched password? you are using the optimized kernel which has the following limitation
Code:
Maximum password length supported by kernel: 8if this doesn't apply to your example, then there could be some more reasons why it won't work
your hash is wrong, can you post you used example pass and your output?
encoding problems with non ascii chars in the password
