The next time you can complete 10^16 on salted md5 fast enough to win a round, let me know. You are looking for 2.77TH/s if the round wait time is roughly an HOUR long. That's 2777000000000 attempts...

Thread: brute force with 11 length password(MD4)
Post: RE: brute force with 11 length password(MD4)

You tested lowercase hex characters, at length 11. Are you certain that the hash you have is MD4, the plaintext is exactly 11 characters, and the plaintext consists only of lowercase hex characters?

Yes, Combinator3 is actually a tool we distribute in the hashcat-utils. It will still be a bit of a hefty task if you start applying rules to them but it is, from a technical standpoint, pretty easy t...

Thread: Cracking partial hex seed for Ethreum Presale
Post: RE: Cracking partial hex seed for Ethreum Presale

IIRC you can't separate the Keccak from the AES step in Presale format as it requires you to decrypt the full ciphertext and hash that with keccak to verify.

Thread: Hash File No Hashes Loaded error.
Post: RE: Hash File No Hashes Loaded error.

Well, first you should probably be specifying -a 0, not -a 3 since you seem to trying to load wordlists, not a mask. Second, it seems like your hash.txt file is empty, since hashcat is unable to find ...

The "2TB" of memory on the SSG, doesn't work like that. It's more of a local filesystem buffer to eliminate the bottleneck of going between system storage and the GPU over the PCI-e connection. You wi...

You will not be able to run it on an SSG any faster than on a VEGA64, as it simply does not work like that, at least to my knowledge. The SSD on the SSG is used as an extended buffer to replace system...
