Struct KeyPair 

pub struct KeyPair { /* private fields */ }

An Ed25519 key pair with secure memory handling.

The secret key is zeroized on drop to prevent leaking sensitive material.

Implementations

impl KeyPair

pub fn generate() -> Self

Generate a new random key pair.

pub fn from_secret_key(bytes: &[u8]) -> CryptoResult<Self>

Create from a secret key (32 bytes).

Errors

Returns CryptoError::InvalidKeyLength if the slice is not exactly 32 bytes.

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

Get the public key bytes (32 bytes).

pub fn key_id(&self) -> [u8; 8]

Get a short key ID (first 8 bytes of public key).

Useful for identifying keys in logs without exposing the full key.

pub fn key_id_hex(&self) -> String

Get the key ID as a hex string.

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

Sign a message.

pub fn verify(&self, message: &[u8], signature: &Signature) -> CryptoResult<()>

Verify a signature (convenience method using our public key).

Errors

Returns CryptoError::SignatureVerificationFailed if verification fails.

pub fn export_public_key(&self) -> PublicKey

Export the public key for serialization.

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

Export the secret key bytes (careful - sensitive!).

This should only be used for secure storage.

Trait Implementations

impl Debug for KeyPair

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

Formats the value using the given formatter.

impl Drop for KeyPair

fn drop(&mut self)

Executes the destructor for this type.
