Signature entity.

Required Associated Types

type Signer: Clone

An entity that produced this signature.

type Key

Key used to create this signature.

Required Methods

fn signer(&self) -> Option<Self::Signer>

An entity that produced this signature.

fn verify_bytes<M>( &self, message: M, key: &Self::Key ) -> Result<bool, VerificationError>where M: AsRef<[u8]>,

Returns Ok(true) if the underlying signature was produced on supplied bytes using the given key.

Implementors

impl<D> Signature for DidOrDidMethodKeySignature<D>where D: Into<DidOrDidMethodKey> + From<DidOrDidMethodKey> + Clone,

type Signer = D

type Key = DidKeyOrDidMethodKey

impl<D> Signature for DidSignature<D>where D: Into<Did> + Clone,

type Signer = D

type Key = DidKey

impl<DK> Signature for DidMethodKeySignature<DK>where DK: Into<DidMethodKey> + Clone,

Verifies that did’s key with id key_id can either authenticate or control otherwise returns an error. Then provided signature will be verified against the supplied public key and true returned for a valid signature.

type Signer = DK

type Key = DidMethodKey
