Struct EncryptionKey 

pub struct EncryptionKey {
    pub did: Did,
    pub key_type: String,
    pub public_key: PublicKey,
    pub public_key_multibase: String,
    /* private fields */
}

X25519 encryption key for envelope key agreement.

Used to compute shared secrets via Diffie-Hellman for encrypting and decrypting Envelope payloads.

Examples

use ma_did::{Did, EncryptionKey};

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

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

Fields

did: Did

key_type: String

public_key: PublicKey

public_key_multibase: String
