This oclHashcat version 2.00 is all about Open-Source. Yes, you read it right. We went Open-Source!

If you want to read more about the background of this, you can find the details here: https://hashcat.net/forum/thread-4880.html

Beside that, there's also alot of changes from the previous version 1.37 to this version.

Most important changes

Bitsliced GPU kernel of the DES based algorithms LM and DEScrypt
TrueCrypt cracker is now full-featured
Removed Timebomb-, Beta- and Keyfile- checks
Added support for all AMD Fiji based GPU (Fury)

Newly added algorithms

Blockchain, My Wallet
MS-AzureSync PBKDF2-HMAC-SHA256

Bitsliced GPU kernel

Bitsliced DES code was an important thing to add, many people were looking for this feature for a long time. If you want to know more about the details of how the implementation went you can read about the details here: https://hashcat.net/forum/thread-4761.html

But to shortcut it, the status is that -m 1500 (DEScrypt) and -m 3000 (LM) now both use bitsliced code for Brute-Forced attacks. Two more things will be done soon:

Support for bitsliced Oracle-DES and RACF
Support for hardcoded salt in DEScrypt

Once we finish the hardcoded salt in DEScrypt we can expect even more performance.

Make sure to monitor oclHashcat's GitHub repository if you're interested in this.

TrueCrypt cracker

The previous release version of oclHashcat (v1.37) was already able to crack TrueCrypt volumes, though it only is able to crack AES encrypted volumes.

With oclHashcat v2.00 we added the following functionality:

Crack Serpent
Crack Twofish
Crack cascaded ciphers
Crack keyfile-protected volumes

That means we finally have a full-featured TrueCrypt cracking engine. It supports all hashes, ciphers, cascades, keyfiles, hidden-volumes, bootable-devices in any possible combination.

But beside that, we also found a way to speed up TrueCrypt cracking massively!

If you're interested in this, please read my post "Cracking eight different TrueCrypt ciphers for the price of three": https://hashcat.net/forum/thread-4812.html

ATM, oclHashcat is the only cracker able to perform this attack.

That is so positive, thank you for that.

Thank you!

RE: oclHashcat v2.00 - 10fi - 12-16-2015

Hey all,

there is a new version available - 2.01:

https://hashcat.net/oclhashcat/

I guess that this was just a quickfix and that's why no new subject was started, however I would appreciate it - than I get an email about new topic (and therefore new version) and I get to know the changelog.

I hope that the mask attack was fixed Smile

RE: oclHashcat v2.00 - magnum - 12-17-2015

I believe you forgot to update the performance matrix on https://hashcat.net/oclhashcat/ (specifically the LM speeds).

Thank you!
