Struct sc_network::service::signature::Signature

pub struct Signature {
    pub public_key: PublicKey,
    pub bytes: Vec<u8>,
}

A result of signing a message with a network identity. Since PeerId is potentially a hash of a PublicKey, you need to reveal the PublicKey next to the signature, so the verifier can check if the signature was made by the entity that controls a given PeerId.

Fields

public_key: PublicKey

The public key derived from the network identity that signed the message.

bytes: Vec<u8>

The actual signature made for the message signed.

Implementations

impl Signature

pub fn sign_message( message: impl AsRef<[u8]>, keypair: &Keypair ) -> Result<Self, SigningError>

Create a signature for a message with a given network identity.

pub fn verify(&self, message: impl AsRef<[u8]>, peer_id: &PeerId) -> bool

Verify whether the signature was made for the given message by the entity that controls the given PeerId.
