The signature that call outputs - which one is R and which one is S? The length of the signature seems to always be twice the length of the private key.
I'm assuming the first half of the signature is R? And the back half is S?
Are they in little endian or big endian form?
I need to present the signature to the bitcoin network and I'm having a little bit of trouble getting it to accept the signature. Which is weird because the public and private keys all check out on both ends. Both sides agree the key pair is good, but the check sig fails on the bitcoin side when presented with the card's signature :(
