You will need to reformat the lines in such a way that the username or salt fields can be used to pair the emails with the hashes. It shouldn't be very difficult, here's an example format. user:...

It should still be possible to both reformat and pair the lists.

What wallet/client are you interested in cracking? It's possible that you could use one of the modes in hashcat with just a different round setting. It's also possible you need more than just the pbkd...

Post: RE: Warp Wallet Challenge 2

I've already looked into this challenge once before, as well as worked on attack code for it. The keyspace is VERY large for the algorithm so it become a bit of an issue if you try and attack it.

You will likely be interested in the code on this page more than anything else: https://github.com/neo-project/neo/blob/25e59cdb0fea65466ad962dd14b02c50384e731f/neo/Cryptography/Helper.cs

Do you have source code for this wallet? I can look into it and see if the algorithm is supported by hashcat.

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.

You must crack the second password. BTCRecover is capable of cracking said password and the base64 value you were given is required to crack the password, although I'm not sure if --extract allows for...

Run the test again but with the CPU disabled as it is by default. Your high usage of the CPU is likely capping the performance of the integrated graphics.

That would be the new kernels, supporting the plaintext/salt lengths of up to 256, making your speeds seem slower. Speed isn't free. If you want more speed, you need to do things like limit plaintext ...

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.
