Post: RE: Cracking password protected PDF documents

Hehe, awesome as usual, congratulations, Jens. So, this only applies to PDFs up to Acrobat v4. v5 and 6 implements 128 bit RC4, v7 128 bit AES and X and later 256 bit AES.

Post: LM hash support for OCLHC

I'd wish to see it.:) It may not be bitsliced. Ofc, it may not be possible to implement with current oclhc architecture(because of 7+7 password length limit). Not top priority.

I could do Russian, but I'd like to know, which encoding should I use for the file itself, the native one(cp-1251) or something universal(utf-7/8)?

Dar she is. It's win-1251 and also, I've included "â„–" there for good reason - it's not a part of ?s, but it's present on Russian keyboards. Okay. If you don't like it, it's the first charact...

According to my preliminary calculations, 1080 should do ~18129M p/s at stock clocks (no boost) for MD5, but since it's derived from old gen's data (Maxwell), the estimation should be skewed, either u...

I bet the lowest belong to the stock clock of 1607 Mhz, and the other results are from overclocking the GPU by a bit. I'm not a fan of automated overclocking shenanigans and luckily GTX Titan has sta...
