Create cryptographically secure UIDs safe for both cookie and URL usage. This is in contrast to modules such as rand-token and uid2 whose UIDs are actually skewed due to the use of
%
and unnecessarily truncate the UID.
Use this if you could still use UIDs with -
and _
in them.Installation
$ npm install uid-safe
API
var uid = require('uid-safe')
uid(byteLength, callback)
Asynchronously create a UID with a specific byte length. Becausebase64
encoding is used underneath, this is not the string length. For example,
to create a UID of length 24, you want a byte length of 18.uid(18, function (err, string) {
if (err) throw err
// do something with the string
})
uid(byteLength)
Asynchronously create a UID with a specific byte length and return aPromise
.Note: To use promises in Node.js prior to 0.12, promises must be "polyfilled" using
global.Promise = require('bluebird')
.uid(18).then(function (string) {
// do something with the string
})
uid.sync(byteLength)
A synchronous version of above.var string = uid.sync(18)
