Wouldn't ask, if I had the capabilities to do it on my own...
Thanks in advance! |

How do you unsalt it? I have John running on the md5 hash, but I don't understand the use of the salt |
You actually aren't able to "unsalt" something. Salting means, that the salt changes the way of encryption. In case of DES for example, it changes the initialization-parameters of the algorithm (if I recall right), in case of MD5 it is mostly in front of the password.
Little example:
Password: bar
Salt: foo
Password to hash: foobar
So if you want to crack the hash, you'll have to put "foo" in front of the password you're trying. | That's not exactly right. Salting means that there is an extra level of security thrown into the hashing process so that, in the event of retrieving some passwords from a forum or something else, it is much harder to crack the passwords.
Example: 5d41402abc4b2a76b9719d911017c592 -> hello
You can try googling this hash and you will almost certainly find it in its unhashed form. Not hard right?
Now try: 2c2280813654075fed0b359d12856099
You can't right this online if you google it, though the password inside of it is still 'hello'. Why? Because I hashed the password twice, the second time with a certain small string on the end (e.g. the salt). This is how vBulletin hashes it's passwords in its databases.
The only way to unhash a salted password is to a) know the salt and b) know the salting scheme.
Invision Power Salt Scheme: MD5(MD5(salt).MD5(password))
vBulletin Salt Scheme: MD5(MD5(password).salt)
etc...
So then to decrypt them you have to account for these factors and then run a program to hash 'test' passwords in the same manner and check to see if the hash then is equal to the one you have. If it is, you have found a 'collison', and thus, the password.*
* In exceedingly rare circumstances, a collison may not be the password but rather another string combination that produces the same hash. |
