 When no options are supplied EC P-256 (also known as `prime256v1` and `secp256r1`) is used by default.
 
-#### Keypairs.parse(options)
-
-Parses either a JWK (encoded as JSON) or an x509 (encdode as PEM) and gives
-back the JWK representation.
-
-Option Examples:
-
-* JWK { key: '{ "kty":"EC", ... }' }
-* PEM { key: '-----BEGIN PRIVATE KEY-----\n...' }
-* Public Key Only { key: '-----BEGIN PRIVATE KEY-----\n...', public: true }
-* Must Have Private Key { key: '-----BEGIN PUBLIC KEY-----\n...', private: true }
-
-Example:
-
-```js
-Keypairs.parse({ key: '...' }).catch(function (e) {
-  // could not be parsed or was a public key
-  console.warn(e);
-  return Keypairs.generate();
-});
-```
-
-#### Keypairs.parseOrGenerate({ key, throw, [generate opts]... })
-
-Parses the key. Logs a warning on failure, marches on.
-(a shortcut for the above, with `private: true`)
-
-Option Examples:
-
-* parse key if exist, otherwise generate `{ key: process.env["PRIVATE_KEY"] }`
-* generated key curve `{ key: null, namedCurve: 'P-256' }`
-* generated key modulus `{ key: null, modulusLength: 2048 }`

-Keypairs.parseOrGenerate({ key: process.env["PRIVATE_KEY"] }).then(function (pair) {
