I found it on Atari Cd Library - CD 09 - a folder full with files with extension GRB. According some cryptic info, files with GRB extension is full version of software, but I didn't understand is there any key to unlock this software, or just some program which "unlocked" files...
As i said , there's a lot of software, collecting from (I think) various sources, and then locked/compressed/other with some unknown program (for me, of course!) And I have this CD, but still don't understand how to unlock or whatever this software:-)
After performing some cryptoanalysis on the files, I was able to deduce the encryption algorithm that was used. Fortunately, this algorithm is prone to an attack that allows the recovery of the decrypted data without knowledge of the key. Find attached a decrypted file as proof. I think it's OK to post this here, since in the meantime Boxkite has been released as freeware.
Which applications other than those you posted are on your CD, BTW? Maybe something that was lost until now? Then I could recover it by decrypting the file...
You do not have the required permissions to view the files attached to this post.
Here's the list of programs, seems like older versions , but, all are or freeware or abandoned, so I can't see any problem to post it here:-)
They all sound familiar. Just search for them in the UTD and you'll see a list of public domain disks and CDs which include these programs. PIAG should be Play It Again GEM, officially declared freeware by the author: http://www.dirk-hagedorn.de/?page_id=13
