We managed to decrypt firmware and also discovered how to dump any firmware. Some known information about encryption Used encryption is not very advanced, not DES or AES. Based on statistical analysis I found that it uses dynamic 256 byte key and XOR operations. text/html 2015-08-21T08:53:03+00:00 http://personal-view.com/faqs/pentax-hack/hack-development?rev=1440147183&do=diff Note! It is information related to old cameras. It is place where information from pentax-hack.info will be residing now.

I took some information from this abandoned project. Firmware hack thread by Rule 34 on DPReview forums. Contains some extra information, but not much. Most information on links in this thread is not available anymore. text/html 2015-08-21T08:54:12+00:00 http://personal-view.com/faqs/pentax-hack/processor-module?rev=1440147252&do=diff Pentax K-5 also uses FR based LSI. With same two CPUs (called CPU and DSP to be exact). FR processor module for IDA Pro 5.0 Free. Download here - Extract and copy to your IDA Free folder. Note - module has one nasty bug making Access violation error during initial database forming.
