Help with cracking

[7461342]

I’m taking a class where we generated passwords and salts with python using the following code:

Code:

#!/usr/bin/python from hashlib import * import binascii salt = '3d10c0082e0a2f7d' pw = 'cat' salt = binascii.unhexlify(salt) m = md5(salt) m.update(pw) s = sha1(salt) s.update(m.digest()) s.update(pw) print s.hexdigest() print pw print "----\n"

In my file, I have

user:<salt>:<hash>

I’ve attempted to crack these but I’m running into problems with them.  What I tried to do is take a dictionary list, run the list into the pw variable and compare the outputted hash with the hash in the password file.  This worked for like 2 passwords and then that’s all.  

I was wondering if HashCat would be able to crack something like these…

Thanks!

Yes, but you need a custom kernel for this custom algo
