I really liked the answer in this post:
However I do not really understand this part:
"taking the signature s raised to the power of 3 modulus n we wind up with the following value"
I see where the strings come from but could someone point me to a box filling operation or perhaps some OpenSSL code so that I can generate the resultant string shown.
I have a VAG MIB2 with QNX, which uses the metachecksum and signatures. So I feel that if I can emulate the process described, I'd have a go and see where it leads.
