Struct SigningKey 

pub struct SigningKey {
    pub did: Did,
    pub key_type: String,
    pub public_key_multibase: String,
    /* private fields */
}

Ed25519 signing key for document proofs and message signatures.

Examples

use ma_did::{Did, SigningKey};

let did = Did::new_url("k51qzi5uqu5dj9807pbuod1pplf0vxh8m4lfy3ewl9qbm2s8dsf9ugdf9gedhr", None::<String>).unwrap();
let key = SigningKey::generate(did).unwrap();

let signature = key.sign(b"hello world");
assert!(!signature.is_empty());

// Export and reimport private key bytes
let bytes = key.private_key_bytes();
let did2 = Did::new_url("k51qzi5uqu5dj9807pbuod1pplf0vxh8m4lfy3ewl9qbm2s8dsf9ugdf9gedhr", None::<String>).unwrap();
let restored = SigningKey::from_private_key_bytes(did2, bytes).unwrap();
assert_eq!(key.public_key_multibase, restored.public_key_multibase);

Trait Implementations

impl Clone for SigningKey

fn clone(&self) -> SigningKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl TryFrom<&SigningKey> for VerificationMethod

type Error = MaError
