Thread: 3Des - ECB brute forcing
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... |

Thread: PHD hashrunner 2013
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: Support for new ASP.NET password storage practices
Post: RE: Support for new ASP.NET password storage pract...
| 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... |

| 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).

Thread: 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... |

| 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... |
