Struct coins_bip32::ecdsa::recoverable::Signature [−][src]
Ethereum-style “recoverable signatures” which allow for the recovery of
the signer’s VerifyingKey from the signature itself.
This format consists of Signature followed by a 1-byte recovery Id
(65-bytes total):
r: 32-byte integer, big endians: 32-byte integer, big endianv: 1-byte recoveryId
Implementations
impl Signature[src]
Re-exported signer traits
pub fn new(
signature: &Signature<Secp256k1>,
recovery_id: Id
) -> Result<Signature, Error>[src]
signature: &Signature<Secp256k1>,
recovery_id: Id
) -> Result<Signature, Error>
Create a new recoverable ECDSA/secp256k1 signature from a regular
fixed-size signature and an associated recovery Id.
This is an “unchecked” conversion and assumes the provided Id
is valid for this signature.
pub fn recovery_id(self) -> Id[src]
Get the recovery Id for this signature
pub fn from_digest_trial_recovery<D>(
public_key: &VerifyingKey,
digest: D,
signature: &Signature<Secp256k1>
) -> Result<Signature, Error> where
D: Clone + Digest<OutputSize = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>, [src]
public_key: &VerifyingKey,
digest: D,
signature: &Signature<Secp256k1>
) -> Result<Signature, Error> where
D: Clone + Digest<OutputSize = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>,
Given a public key, message digest, and signature, use trial recovery to determine if a suitable recovery ID exists, or return an error otherwise.
pub fn recover_verify_key_from_digest<D>(
&self,
msg_digest: D
) -> Result<VerifyingKey, Error> where
D: Digest<OutputSize = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>, [src]
&self,
msg_digest: D
) -> Result<VerifyingKey, Error> where
D: Digest<OutputSize = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>,
Recover the public key used to create the given signature as a
VerifyingKey from the provided precomputed Digest.
pub fn recover_verify_key_from_digest_bytes(
&self,
digest_bytes: &GenericArray<u8, <Secp256k1 as Curve>::FieldSize>
) -> Result<VerifyingKey, Error>[src]
&self,
digest_bytes: &GenericArray<u8, <Secp256k1 as Curve>::FieldSize>
) -> Result<VerifyingKey, Error>
Recover the public key used to create the given signature as a
VerifyingKey from the raw bytes of a message digest.
pub fn r(&self) -> NonZeroScalar<Secp256k1>[src]
Parse the r component of this signature to a NonZeroScalar
pub fn s(&self) -> NonZeroScalar<Secp256k1>[src]
Parse the s component of this signature to a NonZeroScalar
