BPSignFixedK
Cryptography
Description
Produces an ECDSA signature with a caller-supplied nonce
Syntax
Delphi
Function BPSignFixedK(...);Remarks
Part of the pure-Pascal Brainpool ECDSA suite covering brainpoolP256r1, brainpoolP384r1 and brainpoolP512r1 (RFC 5639). Arithmetic runs on a shared 528-bit limb core; group operations use Jacobian coordinates. Signing takes the nonce from the caller so random or deterministic (RFC 6979) policies remain in the integrator's control
