Deterministic nonce derivation

The following vectors verify the deterministic r derivation. All values are fixed; an implementation MUST reproduce e and s exactly.

a:  0000000000000000000000000000000000000000000000000000000000000002
A:  02c6047f9441ed7d6d3045406e95c07cd85c778e4b8cef3ca7abac09b95c709ee5
B_: 02a9acc1e48c25eeeb9289b5031cc57da9fe72f3fe2861d264bdc074209b107ba2
C_: 0244eccfc7a348274458bb38044c7f3c389b3c2086c7ec18b5812d2877ab937787

e: 2a16ffee280aff3c429045607f9b8e0bf8b35910c44c1b20b9dfaf01b263d7b3
s: 9df27731238334718d120d4f74611a7c668233f988e687ac3fb188f0a34a2dab

Verification (e == hash(R1, R2, A, C_)) MUST pass.

DLEQ verification on BlindSignature

The following is a BlindSignature with a valid DLEQ proof.
