The $300 free credit excludes you from using any GPUs at all. GPUs are only available as a paid feature.

Post: RE: Quad 1080ti Workstation

From what I have seen on eBay, there are quite a few used GTX1080Ti popping up (probably because of the impending R2080Ti release) I reckon wait a little bit and once the flood of used GPUs is well...

Cheers @philsmd - I went to test it and run into another issue preventing -m 14000 from working, so I raised it as an issue in Github. Thanks!

In the context of my question, an "invalid" key doesn't just mean the wrong key for my hash - it means a key that cannot be used with the DES cipher.. I understand a candidate is - just not what th...

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

You don't have enough information to be able to recover a key. Put simply, if you only know the first three bytes of the ciphertext, then that leaves 5 bytes unknown, which leaves up to (2^40) = 1,...

Post: RE: Which step am I missing - DES-OFB Key

You have mis-understood the implementation of DES-OFB somewhat. Each round of DES-OFB gives you 64 bits of keystream, that is XORed with your plaintext to give you 64-bits of ciphertext. I'm not sure ...
