From the above algo the length of C is 0x68 bytes but from the log I have the cmd03 payload is 0x6C. What's going wrong ??

again.. you have log only from non original ci module.. try make loh from provider STB or CI module and decrypt all commands step by step and you will be see

Unfortunately I have no access to the equipment you suggest. If you have such log you or someone else please send it to me.

A doubt,
The pdf says "Data88 = First 0x18 hex bytes are expanded using NNRSA idea expand which will generate 2 Prime numbers 0x34 bytes each."

We know;
Data88 = FF4D54D984C85F83E0441945FC56B213243ABA7FBC24D05B 9D7EEE .......... 34F15CD99C269B83568114C
First_18 = FF4D54D984C85F83E0441945FC56B213243ABA7FBC24D05B

Can someone expand First_18 and show me the values of p_34 and q_34?
I got :
Data ..: ff4d54d984c85f83e0441945fc56b213243aba7fbc24d05b
p_34 ..: ae13323b0fdc712e9e7456c83ccf936fa68180eef7a047ea64ae70e4f5c31f75791979eb99c5d34222ae0b666c37010fe2588c3b

p is not prime
q is not prime

But they are not correct because they are not primes.

maybe this is wrong "Data88=First 0x18 hex bytes are expanded using NNRSA idea expand which will generate 2 Prime numbers 0x34 bytes each"
"Data88=First 0x18 hex bytes are expanded using NNRSA idea expand which will generate 2 Prime numbers 0x30 bytes each"

Now ok !

I think that if we have only dt05_10 to the log then we have only generic pairing and the rsa68 is calculated according to pdf. If we had dt05_20 then we had to expand the 0x18 bytes of the unique rsa88 to 2 0x34 primes for the calculation of rsa68. Please tell if I am wrong.

this is not important known for you, because HD+ use only generic pairing mode

hi all

some help about rsa mod 1 & 2

thanks

 

[electron112]

everyone does what they want

klivo you think sec24 does business ok does not help him and the same for others

what's the point of fighting if it's just annoying the forum and its members with stupid topics that won't move anyone forward

Don't forget the world of sat is very small I said and again I know who is who


I ask again my question I would like if possible to have some information on the rsa mod

thank you

Hi,
where i find information about NNRSA idea expand??

Thanks

I don ´ t understand what you want ?
Rsa mods you can find in flashdump, or ramdump

Can someone help me ? I created my own rsas of 1024 bits 0x80 hex to sign my two blocks 016c + 017c but even then deco does not start, what will it lack even more? already signed with mdc5 the two blocks and does not start.

 

[electron112]

Excuse me, I didn't understand what you're trying to do.
you resign your blocks and reinject to the box what's the point of doing this?

and is rsa right?

 

[braza]

This is great nagra secret!
Find out this and you can build your kernel, block 016c and much, much more.

I want to sign one kernel.

Suspect rsa is E2 EE E3 53 AA C2 56 48 0F 61 95 67 C4 13 88 BA , 80 bytes

 

[electron112]

you tested sign just bloc 016C ?
