Struct ecdsa::Signature [−][src]
pub struct Signature<C: Curve + Order> where
SignatureSize<C>: ArrayLength<u8>, { /* fields omitted */ }
ECDSA signature (fixed-size). Generic over elliptic curve types.
Serialized as fixed-sized big endian scalar values with no added framing:
r
: field element size for the given curve, big-endians
: 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 DER-encoded signatures also supported via the
Signature::from_der
and Signature::to_der
methods.
