Struct Ed25519Signature

pub struct Ed25519Signature { /* private fields */ }

An Ed25519 signature.

Implementations

impl Ed25519Signature

pub fn from_bytes(bytes: [u8; 64]) -> Ed25519Signature

Constructs an Ed25519Signature signature from raw bytes.

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

Gets the raw bytes of the signature.

pub fn sign_ed25519(key: &Ed25519PrivKey, message: &[u8]) -> Ed25519Signature

Sign a message.

Ed25519Signature implements Signature, but Signature’s sign function conservatively returns a Result. Ed25519 signatures never fail, so this function is provided to allow the user to compute an Ed25519 signature without having to perform error checking.

Trait Implementations

impl Debug for Ed25519Signature

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Signature for Ed25519Signature

fn sign(key: &Ed25519PrivKey, message: &[u8]) -> Result<Ed25519Signature, Error>

Sign a message.

Though the Signature trait requires that sign return a Result, Ed25519Signature’s implementation is guaranteed to always return Ok. Callers may prefer the sign_ed25519 function, which returns an Ed25519Signature rather than a Result.

type PrivateKey = Ed25519PrivKey

The private key type used to generate this signature.

fn is_valid(&self, key: &Ed25519PubKey, message: &[u8]) -> bool

Verify a signature.
