Struct SigningKey 

pub struct SigningKey { /* private fields */ }

Ed25519 signing key (private key)

This wraps ed25519-dalek’s SigningKey for proper Ed25519 signatures per RFC 8032.

Implementations

impl SigningKey

pub fn generate() -> Self

Generate a new random signing key using a cryptographically secure RNG

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

Create from raw bytes (32 bytes for Ed25519 secret key)

Errors

Returns error if bytes length is not 32

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

Get raw key bytes

pub fn verifying_key(&self) -> VerifyingKey

Derive the verifying (public) key

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

Sign a message using Ed25519

pub fn to_pem(&self) -> String

Export to PEM format

pub fn from_pem(pem: &str) -> Result<Self>

Import from PEM format

Errors

Returns error if PEM format is invalid
