Randomkey

Lightweight node.js lib for generating random strings.

You can specify the length and character set to use.

If you specify length as an array [min, max] a number in the range will be used.

The character set defaults to:

0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz

Several character sets are provided as properties of the function:

• default: 0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz
• upper: ABCDEFGHIJKLMNOPQRSTUVWXTZ
• lower: abcdefghijklmnopqrstuvwxtz
• alphanumeric: 0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZ
• numbers: 0123456789
• safe: 2346789ABCDEFGHJKLMNPRTUVWXTZ

Usage

npm install --save randomkey

randomkey(len, chars)

var rk = require('randomkey');

// generate a 10 character key using the default character set
var key = rk(10);

// generate a 6 character key using only the characters `a`, `b` and `c`
var abc = rk(10, 'abc');

// generate a 16 character key using the "safe" character set:
var safe = rk(16, rk.safe);

// generate a key between 5 and 10 characters long with the default characters:
var variableLength = rk([5,10]);
