Need help for school project

[niklaskar]

Hi there,

I need help for a school project.
I have to bruteforce plain md5,sha1;salted md5,sha1; as well as using dictionary attacks.

I have managed to bruteforce plain md5&sha1 using following options:

Code:

./hashcat-cli32.bin --output-file=cracked.txt -m 100 -a 3 -bf-pw-max=6 -bf-cs-buf=0123456789abcdefghijklmnopqrstuvwyzABCDEFGHIJKLMNOPQRSTUVWXYZ list_sha1.txt dict/

Not exactly sure, what "dict/" helped but it made hashcat execute.

Now I want to bruteforce salted md5 and sha1 hashes.
The hashing is done like "md5($pass.$salt)". The format hash and salt are stored is "$hash:$salt".
How do I need to change my options, so that bruteforcing works for salted hashes?

Yeah I tried that.
At the moment I am trying to use this option:

Code:

./hashcat-cli32.bin -m 1 list_md5_salt.txt -a 3 ?d?d?d?d

I just don't get what my mistake is...
