It's like having your own massive hash-cracking cluster - but with immediate results! This allows you to input an MD5, SHA-1, Vbulletin, Invision Power Board, MyBB, Bcrypt, Wordpress, SHA-256, SHA-512, MYSQL5 etc hash and search for its corresponding plaintext ('found') in our database of already-cracked hashes.

I use the word 'encrypt' although it may not be rigorously correct is a hash lookup service. You may have a look at the source code of crypt for details. Them for md5-hashes, in particular if they are salted. As it has been said already - rainbow tables mayīe reasonable for the old LM hashes (as I had to learn ), but it is ridiculous to create The goal of the iterations is to increase the computationalĮffort to generate a rainbow table. and iterate in a particular scheme by alternating the message 'A' and the salt perform an md5-'encryption' of 'S_2' with the message 'A' -> 'S_3' perform an md5-'encryption' of 'S_1' with the salt -> 'S_2' perform an md5-'encryption' of 'S' with the message 'A' -> 'S_1' Without going too much in detail, the main idea of salting is the following: The reason to use such encryption or compression functions is, that they increase To encrypt a certain start string 'S', e.g.

The message 'A' to be hashed is used as the password Plenty of hash functions actually use an encryption/compression-type function For instance in PHP you have the the following description for crypt: 'string crypt ( string str )' Yes, JtR will crack them and as to why they arent used in databases is because some coders are shitheads, and plenty of people do use them in databases. Because of the salt, you would have to use the salt with each brute force attempt, or use the salt on the dictionary to create a new hash list, and then you have to do it for each password you wish to crack using a different salt. The purpose of the salt is to prevent someone from comparing a pregenerated list of hashes to your hash (or prevent one cracked password from exposing all other accounts with same password). The user's password hash is then created with the entered password and the pseudo-randomly generated salt and stored. The salt in grub is always prepended with '$1$', This is Modular Crypt format where the number indicates the hash algorithm used: 1 = MD5, 2 = Blowfish, 3 = NTHash and the salt is then terminated with a '$'.
