Signature provider based on a keystore

Required Associated Types

type Error: From<Error> + From<<Self::Keystore as Keystore>::Error>

Keystore error implementation

type Keystore: Keystore

Concrete keystore implementation

Required Methods

fn keystore(&self) -> Result<&Self::Keystore, Self::Error>

Accessor to the keystore

Might fail if the keystore is in a corrupt state, not initialized or locked by a concurrent thread.

Provided Methods

fn id_secret( &self, id: &<Self::Keystore as Keystore>::KeyId ) -> Result<Borrown<'_, SecretKey>, Self::Error>

Secret key indexed by id.

fn id_public( &self, id: &<Self::Keystore as Keystore>::KeyId ) -> Result<Borrown<'_, PublicKey>, Self::Error>

Public key indexed by id.

fn sign( &self, id: &<Self::Keystore as Keystore>::KeyId, message: &Message ) -> Result<Signature, Self::Error>

Sign a given message with the secret key identified by id

fn sign_with_key( &self, secret: &SecretKey, message: &Message ) -> Result<Signature, Self::Error>

Available on crate feature std only.
