Struct SigningKey 

pub struct SigningKey(/* private fields */);

Signing key for Ed25519 signatures

Automatically zeroized on drop to protect key material.

Security

• 256-bit private key
• Constant-time operations
• Automatically zeroized when dropped
• Note: Implements Clone for testing convenience, but cloning key material increases exposure. Use sparingly in production code.

Examples

use aion_context::crypto::SigningKey;

let key = SigningKey::generate();
let message = b"test message";
let signature = key.sign(message);

Implementations

impl SigningKey

pub fn generate() -> Self

Generate a new random signing key using OS entropy

Uses the operating system’s cryptographically secure random number generator (/dev/urandom on Unix, CryptGenRandom on Windows).

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Create a signing key from bytes

Errors

Returns AionError::InvalidPrivateKey if the bytes are not a valid Ed25519 private key

pub fn to_bytes(&self) -> &[u8; 32]

Get the bytes of this signing key

Returns a reference to the key bytes

pub fn sign(&self, message: &[u8]) -> [u8; 64]

Sign a message

Creates an Ed25519 signature over the message using this key.

Examples

use aion_context::crypto::SigningKey;

let key = SigningKey::generate();
let signature = key.sign(b"message");
assert_eq!(signature.len(), 64);

pub fn verifying_key(&self) -> VerifyingKey

Get the corresponding verifying key

Trait Implementations

impl Clone for SigningKey

fn clone(&self) -> SigningKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
