note that none of this is strictly relevant to reproducing the bug since we have the byte stream :)

i don't know for sure, but i believe 5 & 7 were only going to be released if the 50% mark wasn't broken. from the "prices" page it looks like they had phpass, postgre, sha1, and broken sha1 hashes.

Post: RE: .cap hash extraction

you are specifying a salted hash mode without supplying the hash and salt in "hash:salt" format. it looks like you are just concatenating the salt with the hash.

hashcat does not support this algorithm. and office2john.py is specific to john the ripper, hence the script's name.

Each thread has its own file descriptor, which mitigates starvation when performing wordlist attacks on multiple GPUs.

No, you must use 14.9. Catalyst 14.12 is broken. oclHashcat isn't broken, Catalyst is.

It's a really bad idea, all you're doing is wasting disk space. And if you have a 100 GB wordlist, you're doing something very, very wrong.

GPU makes sense -- as I said, you should not be running straight wordlist attacks against fast hashes on GPU. However, there shouldn't be that much of a drop between single hash and multihash on CPU. ...
