Struct solders_signature::Signature

pub struct Signature(pub Signature);

The Signature object is a wrapper around a raw bytes signature, typically returned by :meth:~solders.keypair.Keypair.sign_message or other similar methods.

Implementations

impl Signature

pub const LENGTH: usize = 64usize

pub fn new(signature_bytes: [u8; 64]) -> Self

pub fn new_unique() -> Self

Create a random siganture.

Returns: Signature: The random signature.

pub fn new_default() -> Self

Create a new default signature object.

Returns: Signature: The default signature.

Example: >>> from solders.signature import Signature >>> Signature.default() Signature( 1111111111111111111111111111111111111111111111111111111111111111, )

pub fn new_from_str(s: &str) -> PyResult<Self>

Retrieve a signature from a base58-encoded string.

Args: s (str): base58-encoded signature.

Returns: Signature: The decoded signature.

Example: >>> from solders.signature import Signature >>> from solders.keypair import Keypair >>> sig = Keypair().sign_message(bytes([0])) >>> assert Signature.from_string(str(sig)) == sig

pub fn verify(&self, pubkey: Pubkey, message_bytes: &[u8]) -> bool

Check if the signature is a valid signature created by the given pubkey on the given message.

Args: pubkey: The pubkey that is supposed to have signed the message. message (bytes): The message in bytes.

Returns: bool: True if verfiication is successful.

Example: >>> from solders.keypair import Keypair >>> from solders.signature import Signature >>> kp = Keypair() >>> msg = b“macaroni“ >>> sig = kp.sign_message(msg) >>> sig.verify(kp.pubkey(), msg) True

pub fn to_bytes_array(&self) -> [u8; 64]

Returns this signature as a byte array.

Returns: list[int]: the signature as a list of 64 u8 ints.

Example: >>> from solders.signature import Signature >>> assert Signature.default().to_bytes_array() == [0] * 64
