random()​

static random(): PrivateKey

Generate a random private key.

You can obtain the associated public key via toPublicKey. And generate signatures via Signature.create.

Note: This uses node or browser built-in APIs to obtain cryptographically strong randomness, and can be safely used to generate a real private key.

Returns​

PrivateKey

a new PrivateKey.

randomKeypair()​

static randomKeypair(): {
  "privateKey": PrivateKey;
  "publicKey": PublicKey;
}

Create a random keypair { privateKey: PrivateKey, publicKey: PublicKey }.

Note: This uses node or browser built-in APIs to obtain cryptographically strong randomness, and can be safely used to generate a real keypair.

Returns​

{
  "privateKey": PrivateKey;
  "publicKey": PublicKey;
}
privateKey​
privateKey: PrivateKey;
publicKey​
publicKey: PublicKey;
