## Usage ## Usage
### Address
```js ```js
// Generate a new random Bitmessage identity.
var Address = require("bitmessage").Address; var Address = require("bitmessage").Address;
var addr = Address.fromRandom();
console.log("New random Bitmessage address:", addr.encode()); // Generate a new random Bitmessage identity.
var addr1 = Address.fromRandom();
console.log("New random Bitmessage address:", addr1.encode());
// Or create it from passphrase.
var addr2 = Address.fromPassphrase("test");
console.log("Deterministic Bitmessage address:", addr2.encode());
``` ```
