Required Associated Types§
Required Methods§
sourcefn all(key_type: KeyTypeId) -> Vec<Self>
fn all(key_type: KeyTypeId) -> Vec<Self>
Returns all public keys for the given key type in the keystore.
sourcefn generate_pair(key_type: KeyTypeId, seed: Option<Vec<u8>>) -> Self
fn generate_pair(key_type: KeyTypeId, seed: Option<Vec<u8>>) -> Self
Generate a public/private pair for the given key type with an optional seed and
store it in the keystore.
The seed needs to be valid utf8.
Returns the generated public key.
sourcefn sign<M: AsRef<[u8]>>(
&self,
key_type: KeyTypeId,
msg: &M
) -> Option<Self::Signature>
fn sign<M: AsRef<[u8]>>( &self, key_type: KeyTypeId, msg: &M ) -> Option<Self::Signature>
Sign the given message with the corresponding private key of this public key.
The private key will be requested from the keystore using the given key type.
Returns the signature or None if the private key could not be found or some other error
occurred.
sourcefn verify<M: AsRef<[u8]>>(&self, msg: &M, signature: &Self::Signature) -> bool
fn verify<M: AsRef<[u8]>>(&self, msg: &M, signature: &Self::Signature) -> bool
Verify that the given signature matches the given message using this public key.
sourcefn to_raw_vec(&self) -> Vec<u8> ⓘ
fn to_raw_vec(&self) -> Vec<u8> ⓘ
Returns Self as raw vec.
