GUID for JavaScript

Globally Unique Identifier (GUID) is used by developers in websites to generate unique IDs which will increase the security of the website as well as its users. With the help of GUID developers are assured that their online applications are safe as no two identifiers will end up being identical.

It is a very simple idea developed by Microsoft which became a basic standard for security measures. GUID uses complex algorithms which increases the difficulty of attacking the application.

A developer could build and integrate this small application in a website and build a highly effective application. This could be integrated in an Ajax based application for increased security - if there is a GUID builder specifically built for an Ajax based application.

Guid0 as a Security Library

The number of GUID specifically built for JavaScript is very small but these tools have been very effective in increasing the security of the website. One of those popular tools in building GUID specifically made for JavaScript is Guid0.

This library was built by Michael Mahemoff and although it's relatively new, it has shown great potential in helping developers build an application with improved security without having to sacrifice the interactivity of the application.

Advantages of Guid0

Guid0 as we have already indicated is part of a small group of applications that are specifically geared for a programming language. Developers would eventually subscribe to the service especially with JavaScript and in building an Ajax based application.

The niche in this type of application is there and the demand in building this type of application is just increasing. 

Since JavaScript is not able to fully protect itself, it would need the help of other programming languages to enforce that safety. Guid0 is one of those applications that could enforce safety in a very efficient level.

Another advantage of Guid0 is that it could be integrated to the application not as another application but as an API.

Guid0 is small enough to be integrated as an API which does not increase or decrease the footprint of the application. Since its an API, it could be integrated to other Ajax or JavaScript based applications.

Disadvantages of Guid0

Although Guid0 is a very popular library for implementing GUID in JavaScript and Ajax based application, its still not a "complete" GUID as of this writing. For GUID to be fully implemented in an application, it has to enforce 128-bit security.

As of this writing, Guid0 could enforce less than that. Since it doesn't have the same security when compared to the standard GUID, this GUID library only provides limited unique ID.

A regular GUID could provide not only unique IDs but also unique IPs and MAC so that the user could be fully protected. Guid0 could provide unique IDs but it doesn't go as far as providing unique MAC per user.

Guid0 may not be a full fledged GUID for JavaScript and/or Ajax based application. But is already a powerful API that could be integrated to most Ajax and JavaScript based applications for increased security.
