+#### `export`
+
+> Export a key in a PEM encoded password protected PKCS #8
+
+##### `Go` **NYI**
+
+##### `JavaScript` - ipfs.key.export(name, password, [callback])
+
+Where:
+- `name` is the local name for the key
+- `password` is the password to protect the key
+
+`callback` must follow `function (err, pem) {}` signature, where `err` is an Error if the operation was not successful. `pem` is the string representation of the key
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.key.export('self', 'password', (err, pem) => console.log(pem))
+
+-----BEGIN ENCRYPTED PRIVATE KEY-----
+MIIFDTA/BgkqhkiG9w0BBQ0wMjAaBgkqhkiG9w0BBQwwDQQIpdO40RVyBwACAWQw

+> Import a PEM encoded password protected PKCS #8 key

+##### `Go` **NYI**
+
+##### `JavaScript` - ipfs.key.import(name, pem, password, [callback])
+
+Where:
+- `name` is a local name for the key
+- `pem` is the PEM encoded key
+- `password` is the password that protects the PEM key
+
+`callback` must follow `function (err, key) {}` signature, where `err` is an Error if the operation was not successful. `key` is an object that describes the new key.
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.key.import('clone', 'password', (err, key) => console.log(key))
+
+{ Name: 'clone',
+  Id: 'QmQRiays958UM7norGRQUG3tmrLq8pJdmJarwYSk2eLthQ'
