Topic: [SOLVED] Point to BIGNUM conversion
Is there a feature in WolfSSL to conveniently convert an ECC point to a single BIGNUM. A point is 3 BIGNUMs for x, y, and z coordinates in a single struct. For comparison, OpenSSL has a EC_POINT_point2bn function that does this. Incidentally, it also calls the EC_POINT_point2oct which I did not find equivalent for either. This function is called in a firmware library for ECC key pair generation. Anyone else ran into this issue?
