Detailed Usage

import eight from "eight"

const fingerprint = eight({
  hash: "ripe160",  // <sha512 || sha256 || ripe160>
  resolution: true,  // <boolean>
  flash: true,  // <boolean>
  plugins: true,  // <boolean>
  strong: false  // <boolean>
})

fingerprint()
// E9D0C22416262B2F51A4402318060A206620BED2

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

fingerprint({ ip: "39.120.11.2" }) 
// 4402318060A206620BED2E9D0C22416262B2F51A

Pass any param that needs to considered

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: "133.98.32.55" })
// 2416262B2F51A4402318060A206620BED2E9D0C2

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

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

Licence

Eight is semi-private (with security through obscurity in mind) and obfuscated so it's harder to protect against. Is licenced under MIT.
