Re: How can I encrypt data in chunks with AES-128-CBC?

Sorry for the double post. I did it!

The hashes from the decrypted contents now match those encountered on the TMD. Thanks for all your help, tueidj.

To anyone else: the SVN repository is located at http://code.google.com/p/bluedump-mod. Check it out.

Re: How can I encrypt data in chunks with AES-128-CBC?

I wondered about that but there was no IV parameter for encrypt_buffer(), so I figured it was managed internally. Guess not. There actually is, the index value represents the Content Index stored on the TMD for the current content. The encrypt_buffer() function pads it to 16 bytes with zeros. btw, ...

Re: How can I encrypt data in chunks with AES-128-CBC?

Fixed, thanks for the correction. But still no luck about the content verification, the hashes are different. :/ EDIT: Well, it seems like I have to save the last 16 bytes of every new chunk and use that as the IV for the next one, according to some info about Cipher-block chaining I just read. I'll...

How can I encrypt data in chunks with AES-128-CBC?

I'm currently doing a modification of BlueDump that fixes most problems present in the original application, and I want to add support for contents bigger than 45MB (like those present in the "Wii & The Internet" Channel that comes pre-installed in every new Wii). The problem is that, in order to ad...

Re: CleanRip v1.0.5

Yep, I know they're bugfixes, that's precisely why I'm trying to use this revision.

Thanks for the suggestion, though. I'll compile the latest libogc revision from the SourceForge git and post back. :)

EDIT: It worked! Thank you very much, tueidj.

Re: CleanRip v1.0.5

Whenever I compile the latest revision available on the SVN repository (r36), I get a "Write Error!" trying to dump any type of disc. Is there code missing in r36?

Re: Extract the JPG frames of a MTH video file?

Maybe you could use THPView ? It has an option for extracting the frames + sound from the THP files, but considering that MTH files are just muted THPs with minor header differences, *maybe* you can use it for this purpose. I haven't tested it yet with MTH files. Uncompress the RAR in the directory ...
