Struct KeyPair 

pub struct KeyPair { /* private fields */ }

Ed25519 keypair used to sign capsules and related provenance claims.

Implementations

impl KeyPair

pub fn generate() -> Self

Generates a new Ed25519 keypair with operating-system randomness.

pub fn from_bytes(bytes: &[u8; 32]) -> Result<Self, CryptoError>

Constructs a keypair from a 32-byte Ed25519 secret key seed.

pub fn signing_key(&self) -> &SigningKey

Returns the underlying Ed25519 signing key.

pub fn verifying_key(&self) -> VerifyingKey

Returns the corresponding Ed25519 verifying key.

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

Serializes the secret key seed.

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

Returns the public verifying key bytes.

pub fn save_to_file(&self, path: &Path) -> Result<(), CryptoError>

Writes the secret key seed to path.

pub fn load_from_file(path: &Path) -> Result<Self, CryptoError>

Loads a keypair from a file containing exactly 32 secret-key bytes.
