Expand description

A Signature interface, implemented by anything that can hold a private cryptographic signing key.

An implementor must handle all supported cryptographic signing algorithms.

Required Methods§

source

fn id(&self) -> &Identity

Get the corresponding Identity for the private key.

source

fn sign(&self, hash: &Hash) -> Signature

Sign a hash.

source

fn self_export_lock( &self, csprng: &mut dyn CryptoSrc, receive_lock: &LockId ) -> Option<IdentityLockbox>

Export the signing key in an IdentityLockbox, with receive_lock as the recipient. If the key cannot be exported, this should return None.

source

fn self_export_stream( &self, csprng: &mut dyn CryptoSrc, receive_stream: &StreamKey ) -> Option<IdentityLockbox>

Export the signing key in an IdentityLockbox, with receive_stream as the recipient. If the key cannot be exported, this should return None. Additionally, if the underlying implementation does not allow moving the raw key into memory (i.e. it cannot call StreamInterface::encrypt or lock_id_encrypt) then None can also be returned.
