Title: Need help with Seed key algorithm for 27 61 RSA sign Post by: Marty_ on November 05, 2024, 11:19:40 AM Hi all,
I'm trying some stuff with a BMW 7DCT300 TCU as a hobby/learning project and I'm stuck at an seed key routine. Does someone have C/C#/C++/Python code for this TCU so I can see how this routine should work? It seems to be a 16 Byte seed and a 128 Byte RSA sign. The UDS seed security request is 0x07E1 0x02 0x27 0x61. The UDS sign/key sending is 0x7E1 0x10 0x82 0x27 0x61 and 128byte key. It seems that the RSA sign can be forged. Can anyone help me with this. I have a couple of seed/key combinations that worked which I can provide. Thanks! Smile Kind regards, Marty_ Title: Re: Need help with Seed key algorithm for 27 61 RSA sign Post by: prj on November 05, 2024, 01:20:25 PM Sir, this is "Reverse Engineering", not give me free code and make me a sandwich.
How about doing some actual reverse engineering or posting this in paid requests? |
