+
+### RSA.export*(keypair)
+
+You put in an object like `{ privateKeyPem: '...' }` or `{ publicKeyJwk: {} }`
+and you get back the keys in the format you requested.
+
+Note:
+
+* Private keys **can** be used to export both private and public keys
+* Public keys can **NOT** be used to generate private keys
+
+Example:
+
+```javascript
+var keypair = { privateKeyPem: '...' };
+
+keypair.publicKeyJwk = RSA.exportPublicJwk(keypair);
+
+console.log(keypair);
+```
+
+### RSA.signJws(keypair, payload, nonce)
+
+Generates a signature in JWS format.
+
+```javascript
+var message = "Hello, World!"
+var nonce = crypto.randomBytes(16).toString('hex');
+var jws = RSA.signJws(keypair, message, nonce);
+
+console.log(jws);
+```
+
+The result looks like this:
