pub struct Signature<C: Curve + CheckSignatureBytes> where
    SignatureSize<C>: ArrayLength<u8>,  { /* private fields */ }

Expand description

ECDSA signatures (fixed-size).

Generic over elliptic curve types.

These signatures are serialized as fixed-sized big endian scalar values with no additional framing:

r: field element size for the given curve, big-endian
s: field element size for the given curve, big-endian

For example, in a curve with a 256-bit modulus like NIST P-256 or secp256k1, r and s will both be 32-bytes, resulting in a signature with a total of 64-bytes.

ASN.1 is also supported via the Signature::from_asn1 and Signature::to_asn1 methods.
