    Thread: Karbo (karbovanec) wallet bruteforce
Post: RE: Karbo (karbovanec) wallet bruteforce

Looks like its Cryptonote derived so definitely not supported yet. Let me see what exactly was used for your version and see if it's something we should make an issue for supporting.

Ok, it's CryptoNote SlowHash -> ChaCha8. This is slow hash: https://github.com/cryptonotefoundation/cryptonote/blob/master/src/crypto/slow-hash.c The ChaCha8 looks like its just a typical imple...

If self-testing fails, then there is an issue and your drivers are either broken or incompatible with hashcat/that algorithm.

In case you haven't read much around the forums, AMD GPUs tend to be serious fire hazards when running hashcat. Hashcat can be a very very demanding workload, above that of almost anything else. To 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...

Post: RE: Trouble with veracrypt volume

You simply need the first 512bytes of the volume i believe, as it contains the volume header with all the information related to the KDF and the password.

That means it doesnt like the path you have provided to the hash files. I would suggest putting them in the same folder as hashcat and trying again.

In theory, hashcat can run on the RasPi, you can compile it for ARM easily. Now, getting OpenCL might be harder, im not sure the state of OpenCL for the RasPi. As for the Asus Tinker Board, it not onl...

    Thread: Hashcat doesn't load bcrypt hash
Post: RE: Hashcat doesn't load bcrypt hash

Please don't post hashes. Regardless, the hash you are attacking is an Edmodo hash. You can not load hashes from Edmodo directly into hashcat as they are not plain bcrypt(which should be obvious).

Edmodo didn't use plain bcrypt the way I think you are expecting. Their hashes were obfuscated, which should be easy to determine and fix, but also layered with other algorithms, which im sure you can...

You will need to handle that, hashcat can not handle that for you right now.

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.
