    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.

The seed is 64 characters long? Now i'm confused. Ethereum Private Keys are 64 characters long, hex, seeds are typically the multi word phrases used to derive the private key. It's my understanding th...

It's not just about heat on the cards, the cards also like to draw too much power from the PCI-e slot which can damage it, even if the heat itself isn't the direct cause. Commercial GPU chassis such a...

There is a thermal cutoff in hashcat, it's even configurable with a flag. That said, I'd be very careful with hashcat. Mining != max load. Even 100% util != 100% util. You will notice this when swappi...
