Struct PublicKey

An unvalidated any public key: not necessarily an elliptic curve point, just a sequence of 32 bytes

struct PublicKey has copy, drop, store

Constants

There are extra bytes in the input when deserializing a Federated Keyless public key.

const E_INVALID_FEDERATED_KEYLESS_PUBLIC_KEY_EXTRA_BYTES: u64 = 1;

Function new_public_key_from_bytes

Parses the input bytes into a keyless public key.

public fun new_public_key_from_bytes(bytes: vector<u8>): federated_keyless::PublicKey

public fun new_public_key_from_bytes(bytes: vector<u8>): PublicKey {
    let stream = bcs_stream::new(bytes);
    let pk = deserialize_public_key(&mut stream);
    assert!(!bcs_stream::has_remaining(&mut stream), error::invalid_argument(E_INVALID_FEDERATED_KEYLESS_PUBLIC_KEY_EXTRA_BYTES));
    pk
}

Function deserialize_public_key

Deserializes a Federated Keyless public key from a BCS stream.

public fun deserialize_public_key(stream: &mut bcs_stream::BCSStream): federated_keyless::PublicKey

public fun deserialize_public_key(stream: &mut bcs_stream::BCSStream): PublicKey {
    let jwk_address = bcs_stream::deserialize_address(stream);
    let keyless_public_key = keyless::deserialize_public_key(stream);
    PublicKey { keyless_public_key, jwk_address }
}

Function new

Creates a new Federated Keyless public key from a keyless public key and a JWK address.

public fun new(keyless_public_key: keyless::PublicKey, jwk_address: address): federated_keyless::PublicKey

public fun new(keyless_public_key: keyless::PublicKey, jwk_address: address): PublicKey {
    PublicKey { keyless_public_key, jwk_address }
}

Function get_jwk_address

Returns the identifier bytes of the public key

public(friend) fun get_jwk_address(self: &federated_keyless::PublicKey): address

friend fun get_jwk_address(self: &PublicKey): address {
    self.jwk_address
}

Function get_keyless_public_key

Returns the keyless public key of the public key

public(friend) fun get_keyless_public_key(self: &federated_keyless::PublicKey): keyless::PublicKey

friend fun get_keyless_public_key(self: &PublicKey): keyless::PublicKey {
    self.keyless_public_key
}
