: How to you aproach cracking a unknown type of hash ?
: Rusty January 07, 2015, 06:09:51 PM
Is there any guide to how do you aproach cracking a unknown type of hash ?

Hashes are not immediately obvious MD5 or SHA1. Is there any chatsheat I can learn from ?

For example here are some hashes that I can't find any information about the way they are produced:

$H$7uT0JgyTq0/a6y0bS3ADsX0qng7U4L/
$H$7rzeja3ZJEuLcVe0txonotD1nDuOS7/
$H$9PyRpsC/o3MFaQA4JtxTf5p77Xk1E3/
$H$7D8rz0lys1zZomnd2VbrE47cmZPznZ0
$H$7IfeB4LgyvjKVXSisrSG.yx6NOa8/Q.

they all start alike which is probably a tell-tell sign, but search did not get me any results.

Probably are they are easy to you :)

Best regards,
Rusty

[+]  MD5(phpBB3)

hash-identifier is installed on kali by default.

yep hashidentifier is a great tool, its capable of identifying alot of hashes, also if that didnt worked maybe you can google the hash to see any hashes, maybe it has something in common, but as it seems hashidentifier, already identified the hash :)

Since this hasn't been updated for the last two years, i will just blow off some dust on our own version by @Psycho_coder which he rolled last year and does his best to include as many hashes as possible.

Ok, enough marketing, here: http://psychocoderhc.github.io/Hash-Algorithm-Identifier/ (http://psychocoderhc.github.io/Hash-Algorithm-Identifier/)

Nice. Starred on github.
You should try and get a hold of the Kali people and try to get this put in to replace the old one.
I could probably get this into ArchAssault for you.
+1 for you and Psyco_Coder

Thank you all!
What a great answer, didn't not such a tool exist. Some hard work went into building it :)
