how about
game_verify_key.pemCode: Select all
-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDGaB4qEPGgD3jPKPOAbk/BAi+b

-----END PUBLIC KEY-----
?

I don't understand a lot from encryption
Does anyone here for find a secret key?

who said 1.5 hour? My AMD 3200 pc works all over the night and it seems, it will take much more time
I don`t understand encryption too, but this public key is in directory GAME_LIB just after XOR decryption.

Hi juuso,
I'm not sure what you are trying to do, but disassembling a 50-odd MB executable shouldn't take that long. If you are trying to find the private key of the encryption, that's a totally different matter. That may take quite some time.....
grtz,

game_verify_key.pem file doesn`t exist in older firmwares, but exist in 3000.2. What if before flashing u have to delete this file from FW? I guess, w/o this file it will be possible to copy
samygo to tv memory ?
Something was wrong with my computer. It crashed this morning. Another PC takes about 2 hours to disassemble.
Few info about RSA keys:
http://en.wikipedia.org/wiki/Public-key_cryptography . We have public key. Now we need private one. Anybody knows is it possible to generate
private key if we have a
public key?

I found this
Code: Select all
.text:0065D8E0 LDR R1, =a1198282 ; "1198282"
.text:0065D92C LDR R1, =a1194444 ; "1194444"
.text:0065D9A0 LDR R1, =a8158282 ; "8158282"
.text:0065D9C8 LDR R1, =a81588 ; "81588"
.text:0065D9F4 LDR R1, =a81599 ; "81599"
.text:0065DA20 LDR R1, =a81501 ; "81501"
.text:0065DA34 LDR R1, =a81590 ; "81590"
.text:0065DA78 LDR R1, =a30101 ; "30101"
these codes are in FW, but i dont`t know why they dont work.
and this:
Code: Select all
.text:0065E3F4 ; AutoRcInputBase::DebugMenu(void)
.text:0065E3F4 EXPORT _ZN15AutoRcInputBase9DebugMenuEv
.text:0065E3F4 _ZN15AutoRcInputBase9DebugMenuEv ; CODE XREF: AutoRcInputBase::Debuger(void)+10p

.text:0065E430 BL puts

.text:0065E438 BL puts
.text:0065E43C LDR R0, =a99Exit_2 ; " 99 : Exit "
.text:0065E440 BL puts
.text:0065E444 MOV R0, R4
.text:0065E448 LDMFD SP!, {R4,LR}
.text:0065E44C B puts
.text:0065E44C ; End of function AutoRcInputBase::DebugMenu(void)
.text:0065E44C
.text:0065E44C ; ---------------------------------------------------------------------------
I lost way...
Interesting code is there, but i`m not enough good to understand ...

Possible but requires massive computational power. Could be archived by Multi-Machine GPGPU attack. but requires custom application for that.

Yes, few strings..
