    Thread: 3DES with repeating key
Post: RE: 3DES with repeating key

Hi Atom, Any chance that you could implement k1 = k3, and k1 != k2 for 3des? Or could you show me which part of the kernel k3 is, and how to loop/feed k1 into it? Because I have tried a few times, ...

Post: 3des, k1==k3, k1 != k2 kernel

Hi, Could someone show me how to make the current -m 14100 kernel, which is currently k1 != k2 != k3, to be k1==k3, and k1 != k2? Thanks.

Post: RE: Brute-force with only half of the cipher text

I am also looking for something similar, but I know the cipher text, but only 3 bytes out of 8 bytes of the plaintext. Can something be implemented for this in the next version of hashcat? (To exhaust...

Yes, it has to do with the changes that I made. Prior to the changes, my charset and mask was: -1 X:\xxxx\xxxx\xxxx\hashcat-3.30\charsets\DES_full.charset -2 ?1?s --hex-charset ?2?2?2?2?2?2?2?2?2?2?...

Post: RE: hashcat v3.40

I have edited the 3 m14100 files in order to try and get k1=k3 and k1 independent of k2, and compiled hashcat. Now I get integer overflow. Any help on how to set k1=k3 and k1 independent of k2 proper...

Post: 3DES (hc 3.40): K1 == K3 and K1 != K2 possible?

Hi, Thanks for the new version. Mode 14000 (des) works well. For mode 14100 (3des), is it possible to implement K1=K3, and K1 is independent to k2? Thanks.
