Optional trait for signature algorithms that support key serialization

This trait should only be implemented for algorithms where key import/export is safe and well-defined.

Required Associated Constants

const PUBLIC_KEY_SIZE: usize

Size of serialized public keys in bytes

const SECRET_KEY_SIZE: usize

Size of serialized secret keys in bytes

const SIGNATURE_SIZE: usize

Size of serialized signatures in bytes

Required Methods

fn serialize_public_key(key: &Self::PublicKey) -> Vec<u8>

Export a public key to bytes

fn deserialize_public_key(bytes: &[u8]) -> Result<Self::PublicKey>

Import a public key from bytes

Errors

Returns an error if the bytes are malformed or invalid

fn serialize_secret_key(key: &Self::SecretKey) -> ZeroizingBytes

Export a secret key to bytes

Security Warning

The returned bytes contain sensitive key material and must be handled with appropriate care. The exact-size zeroizing wrapper ensures every initialized byte is cleared from memory when dropped.

fn deserialize_secret_key(bytes: &[u8]) -> Result<Self::SecretKey>

Import a secret key from bytes

Security Requirements

• Input bytes should be zeroized after use
• Implementation must validate the key format

Errors

Returns an error if the bytes are malformed or invalid

fn serialize_signature(sig: &Self::SignatureData) -> Vec<u8>

Export a signature to bytes

fn deserialize_signature(bytes: &[u8]) -> Result<Self::SignatureData>

Import a signature from bytes

Errors

Returns an error if the bytes are malformed or invalid

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
