Hi all

I need little help with calculating my rsa and box key from my dump.bin file, I have found the IRD and succesfully detect the whole block with Rsa and boxkey but it's encrypted does anyone knows how I can decrypted.

Thank you all

m8 and this is your 1st post what a cracking question but i have 1 for u how did you get the dump care to share then some 1 will prolly share back 1 post question like that lol

Mate, I really don't know, friend of mine sends me the whole dump, he told me that he perform JTAG from old receiver very old. But he don't know how to decrypt.

Yeah good cracking Intruduction.

What dump do you have is it a ram dump? And what box from?
I have 2 full ram dumps from an old 2100 both with and without the card inserted but obviously the magic question is where to look lol

As for getting the dump you could do with a jtag'abble box makes life alot easier.
Then you will need a soldered jtag as it takes a good few hours. The software you need is the full version of OCDeamon Flash Memory Prgrammer. If anybody needs a copy let me know and I will upload it somewhere and put a link here.

You wont get anything from a flash memory dump !

What about season logger mates ? If I try to sniff out the traffic between the card and STB ?

G77 · 24-12-10, 02:24 PM

season logger isnt any good either.

season = serial = no good

what you need for logging coms between card and box is a at90s8515 logger

Why would you want to sniff comms between card/box ?

Its all encrypted so it would be pretty useless to you. The only reason to do this is if your interested in the actual protocol and how it all works. Other than that you cant learn anything by direct logging.
