Great work, Terra!

I've been experimenting with the integers above in order to gain a better understanding of how asymmetric RSA keys work. In this example, p > q. I swapped p and q and was able to determine the Chinese remainder theorem (CRT) integers.

Code:

dP =
0xb22ddc856a97ca86ab9f34b3f575802df691987293e635f96224bf66ff721375

dQ =
0x77667580b643fa05216c29b33182b8d9847214bbd45ecea2b782e8939a58bbbd

qInv =
0x241aeb70033463d662d83f4a1ff1ebf5e64d1e5dc46b32dfee29baa70feb2760

dP=d mod (p-1)
dQ=d mod (q-1)
qInv=(q^-1) mod p

Decryption using CRT is at least 3X faster.

This is some interesting stuff. Anybody want to do a DIY how to. I'd love to see how to get into the computer and code the thing.

Is there any flash file for BMW X5 E70 30sd? Id like alpina flash for it? Is it possible?

HI, reading alot of really good info (slightly over my head) but wondering if anyone has been able to tune the upshift out of this transmisson in manual mode? thanks in advance.
