Struct phron_finality::crypto::AuthorityPen

pub struct AuthorityPen {
    key_type_id: KeyTypeId,
    authority_id: AuthorityId,
    keystore: Arc<dyn Keystore>,
}

Ties an authority identification and a cryptography keystore together for use in signing that requires an authority.

Fields

key_type_id: KeyTypeId

authority_id: AuthorityId

keystore: Arc<dyn Keystore>

Implementations

impl AuthorityPen

pub fn new_with_key_type( authority_id: AuthorityId, keystore: Arc<dyn Keystore>, key_type: KeyTypeId ) -> Result<Self, Error>

Constructs a new authority cryptography keystore for the given ID and key type. Will attempt to sign a test message to verify that signing works. Returns errors if anything goes wrong during this attempt, otherwise we assume the AuthorityPen will work for any future attempts at signing.

pub fn new( authority_id: AuthorityId, keystore: Arc<dyn Keystore> ) -> Result<Self, Error>

Constructs a new authority cryptography keystore for the given ID and the Phron key type. Will attempt to sign a test message to verify that signing works. Returns errors if anything goes wrong during this attempt, otherwise we assume the AuthorityPen will work for any future attempts at signing.

pub fn sign(&self, msg: &[u8]) -> Signature

Cryptographically signs the message.

pub fn authority_id(&self) -> AuthorityId

Return the associated AuthorityId.
