function sign¶

virtual outcome::result< SR25519Signature > sign(
    const SR25519Keypair & keypair,
    gsl::span< const uint8_t > message
) const =0

Sign a message using the given keypair.

Parameters:

keypair Pair of public and secret sr25519 keys.
message Bytes to be signed.

Return: Signature of the message.

Reimplemented by: sgns::crypto::SR25519ProviderImpl::sign

function verify¶

virtual outcome::result< bool > verify(
    const SR25519Signature & signature,
    gsl::span< const uint8_t > message,
    const SR25519PublicKey & public_key
) const =0

Verifies that the message was signed by the given public key.

Parameters:

signature Signature to verify.
message Message bytes.
public_key Public key to verify against.

Return: true if signature is valid, false otherwise.
