lack of "cookie-parser" dependency info

[mszmida]

In Readme.md file there is no information that this package relies on cookie-parser express middleware existence. Consider reading and writing cookies directly by your package.

There is also no information that JWT token is returned and cookie is being set on GET request automagically by middleware. It is important information in use case of your package with RESTfull API.

The last thing:
(node:2281) Warning: Use Cipheriv for counter mode of aes-256-ctr

Cipher algorithm should be updated, read here.

Thank you for your work :-)
