Pass whatever needed to consider

It's possible to customize fingerprinting with own parameters which are passed as params. This way anything (like cookies, ip adress or username) can be considered.

fingerprint({ ip: "187.30.93.12" })
// 2416262B2F51A4402318060A206620BED2E9D0C2

fingerprint({ cookies: JSON.stringify(cookies) })
// 20BED2E9D0C22416262B2F51A4402318060A2066

fingerprint({ whatever: "ABCDEF" })
// F51A4402318060A206620BED2E9D0C22416262B2

Licence

The whole library is semi-private. Can be used for fingerprinting under MIT, but as a protection (security through obscurity in mind) is obfuscated. This way no one can see what's fingerprinted and developing protection is harder.
