Struct Signature 

pub struct Signature { /* private fields */ }

Signature produced by a Chio SigningBackend.

Algorithm-tagged signature type. Preserves byte-identical serialization and construction helpers for the Ed25519 case; non-Ed25519 paths use the same outer API.

Implementations

impl Signature

pub fn from_bytes(bytes: &[u8; 64]) -> Signature

Create from raw 64-byte Ed25519 signature bytes.

pub fn from_p256_der(bytes: &[u8]) -> Signature

Create a P-256 ECDSA signature from DER-encoded bytes.

pub fn from_p384_der(bytes: &[u8]) -> Signature

Create a P-384 ECDSA signature from DER-encoded bytes.

pub fn from_hybrid_parts( classical: Signature, pq: &[u8], alg_set: &str, ) -> Result<Signature, Error>

Create a hybrid signature from a classical signature and ML-DSA-65 signature bytes.

pub fn from_hex(hex_str: &str) -> Result<Signature, Error>

Create from hex-encoded bytes (with optional 0x prefix).

Bare hex strings are interpreted as Ed25519 (the default algorithm). A p256: or p384: prefix selects ECDSA.

pub fn to_hex(&self) -> String

Hex encoding, with algorithm prefix for non-Ed25519 signatures.

Ed25519 signatures render as a bare 128-character lowercase hex string.

pub fn to_bytes(&self) -> [u8; 64]

Raw 64-byte Ed25519 representation.

For non-Ed25519 signatures returns an all-zero placeholder (such signatures never flow through 64-byte-only consumer paths because those paths are Ed25519-specific on-chain anchoring layers that never see FIPS artifacts).

pub fn algorithm(&self) -> SigningAlgorithm

Which algorithm produced this signature.
