KeyPair

Plain public/private key pair helper.

Import

import { KeyPair } from '@haskou/value-objects';

Signature

class KeyPair

Constructor

constructor(publicKey: PublicKey, privateKey: PrivateKey)

Validation

The constructor relies on PublicKey and PrivateKey validation.

Methods

Method	Description
static generate()	Generates a new key pair.
static fromPrimitives(primitives)	Restores from { publicKey, privateKey }.
encryptKeyPair(password)	Returns an EncryptedKeyPair.
isValidSignature(payload, signature)	Verifies with the public key.
sign(payload)	Signs with the private key.
toPrimitives()	Returns { privateKey, publicKey }.
encrypt(payload)	Encrypts with the public key.
decrypt(encryptedPayload)	Decrypts with the private key.

Example

import { KeyPair, Password } from '@haskou/value-objects';

const keyPair = await KeyPair.generate();
const signature = keyPair.sign('message');

keyPair.isValidSignature('message', signature); // true

const encrypted = await keyPair.encryptKeyPair(
  new Password('Secure-password-123!'),
);

Notes

• toPrimitives() includes the raw private key. Store it carefully.
