Struct Ed25519SigningKey 

pub struct Ed25519SigningKey { /* private fields */ }

An Ed25519 key pair capable of producing signatures.

Implementations

impl Ed25519SigningKey

pub fn generate() -> Result<Self, Error>

Generates a fresh Ed25519 key pair using the system RNG.

Errors

Returns Error::KeyGeneration if the underlying RNG fails, which effectively only happens on platforms where aws-lc-rs cannot initialise a secure random source.

pub fn from_pkcs8_der(der: &[u8]) -> Result<Self, Error>

Loads an Ed25519 key pair from a PKCS#8 DER blob.

Errors

Returns Error::InvalidPkcs8 if the DER cannot be decoded as an Ed25519 PrivateKeyInfo.

pub fn to_pkcs8_der(&self) -> &[u8]

Returns the PKCS#8 v2 DER encoding of the private key.

pub fn public_key(&self) -> Ed25519PublicKey

Returns the corresponding public key.

Panics

Panics only if aws-lc-rs produces a public key whose length is not exactly 32 bytes — which the Ed25519 algorithm forbids by construction. A panic here therefore indicates a bug in aws-lc-rs and not in our code.

pub fn sign(&self, message: &[u8]) -> Vec<u8>

Produces a detached Ed25519 signature over message.

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

Formats the value using the given formatter.
