Where nonce1 and nonce2 is suppose to represent some kind of key.
There are 5 help files and 5 manual files. They don’t interact at all and work completely independently from each other, can be opened from DesignaKnit or from a file browser window, are not available until the program is purchased and installed, each may be downloaded as a PDF. What we have found with this infection is that if you XOR the first byte of the cipher text with the plain text, you get a key byte you can use to get the first byte of every file back. Which makes sense with this function because the first time in the loop the key is added to 0, which means it is simply the key. But then this guy used some type of weird CFB type xor encryption where it uses the previous xor'ed byte with the key next. I just don't quite understand the function and I was hoping somewhere here could perhaps simplify it more for me or explain it.
I also know C#, and VB if anyone would know how to explain the function in these languages.
