bigrandom v1.1.3

bigrandom

Generate 128 bit random numbers for use as unique ids.

For Node.js at https://www.npmjs.com/package/bigrandom .

Use

Simple example:

var bigrandom = require('bigrandom');

var random128bitHexString = bigrandom();

For more entropy, anything can be passed in as salt:

var moreRandom128bitHexString = bigrandom([req.headers, req.body]);

Example result:

"fa3f25fcd6a415285bc079c1924cbfdc"

Desgin goals

• Truly random: Don't allow conclusions about time of creation.
• Truly random: Don't allow conclusions about IP addresses or number of servers.
• Better random: Maximize entropy.
• Also fit for use in URLs.

TODO

Make same name function for use in browsers. Should and must get some of entropy differently.
