Uniqd

Uniqd is a irreversible ObjectId generator tool. Need a unique id for something? Uniqd is for you.

How to use?

Simple, just install it, require it and use it

• Install it: npm install edge-uniqd
• Require it:

    let uid = require('edge-uniqd');

    console.log(uid); // 00a4acfcdf2205cb89e8ea721e8def45

Under the hood

Uniqd will always return a 32bit ObjectID string, but what makes it really unique and irreversible? Well, first of all the script generate enough entropy taking some special data of the PC, like:

• The time in seconds at the momment of the exection.
• The ProcessId (pid).
• The fingerprint of your PC.
• A random 16bits ID string.

The fingerprint is where all the "heavy" entropy is made because the script makes a big string with this data:

• freemem
• homedir
• hostname
• uptime
• user
• mac-adress
• IP

Then we take this full data an hash it with crypto.createHash and the md5 algoritm... the result is an irreversible 32bit hasehd string.
