Lame I was hoping this would be 16 but it's 32: Code: -- echo mcrypt_get_key_size('twofish', 'cfb'); -- So the key is the MD5 of the username and password (the key is in hex). I'm just going to...

Azren, I think epixoip missed this line: Code: -- $key = trim($username).trim($cleartext_password); -- This is a very weird construction it's encrypting the password with the password. You can thi...

    Thread: Openwall cracker ?!
Post: RE: Openwall cracker ?!

The "full" keyspace is 69^7 so 1.5 hours vs 24 minutes. Unless you add in foreign characters. These change depending on the system's code page. I tried to figure out the mapping and failed because ...

Post: RE: 3Des - ECB brute forcing

Well we know the ciphertext of 12345678, password, and adobe123. So that's enough needed. Also you wouldn't brute force this you would take all 2^56 keys and encrypt one of the plaintext blocks. Stori...

Post: RE: Huge wordlist

Without knowing what you are doing, I'd suggest removing the last character from all the words in the word list. Sort and remove duplicates. Then do a hybrid attack to add the last character back in. ...

Post: RE: Haswell bench

Man and I was hoping for a nice speed increase. If you compare the speed to Hashcat it'll probably be on par (hashcat -m 3200 -n 1 -a 3 bcrypt.txt ?a?a?a?a?a). Hashcat might be faster since I just rea...

Post: RE: PHD hashrunner 2013

I think I saw this somewhere, but I love the idea. Everyone submits a password list/generation info for 1M, 1G, 1T, 1P, or whatever. Then when a major password breach happens you test those passwords ...

    Thread: Saving calculated hashes
Post: RE: Saving calculated hashes

You need to write a program that will hash using SSE2/SSSE3/AVX to make it fast. You should write truncated binary hashes to the file. Since I guess you want to make it useful, you should make a lossy...

Who thought that "PBKDF2_SHA1(pw, salt, 1000, 256)" is a good idea? Because CPU hash crackers are going to: * Checking the first 160 bits gets you 2x faster than defender. * SSE2 gets you 4x faster...
