Struct StoredKeypair 

pub struct StoredKeypair {
    pub key_id: KeyId,
    pub created_at: OffsetDateTime,
    pub secret_key: String,
    pub public_key: String,
}

An Ed25519 keypair stored as base64-encoded strings with metadata.

Fields

key_id: KeyId

Unique identifier for this keypair.

created_at: OffsetDateTime

Timestamp when the keypair was generated.

secret_key: String

Base64-encoded Ed25519 secret key (32 bytes).

public_key: String

Base64-encoded Ed25519 public key (32 bytes).

Implementations

impl StoredKeypair

pub fn generate() -> Self

Generates a new random Ed25519 keypair.

pub fn signing_key(&self) -> Result<SigningKey, CryptoError>

Decodes and returns the Ed25519 signing key.

pub fn verifying_key(&self) -> Result<VerifyingKey, CryptoError>

Decodes and returns the Ed25519 verifying (public) key.

pub fn secret_key_bytes(&self) -> Result<[u8; 32], CryptoError>

Returns the raw 32-byte secret key.

pub fn sign_bytes( &self, payload: &[u8], ) -> Result<MessageSignature, CryptoError>

Signs raw bytes and returns a detached MessageSignature.

pub fn sign_json<T: Serialize>( &self, payload: &T, ) -> Result<MessageSignature, CryptoError>

Serializes payload to canonical JSON, then signs the bytes.

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

Writes the keypair to a JSON file with restrictive permissions (0600 on Unix).

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

Reads a keypair from a JSON file at the given path.
