Introduction to Adobe AIR: Part 5

In this tutorial we will talk about digitally signing your AIR applications.

When you are ready to start destributing your application, you'll be required to digitally sign it. Without the digital certificate - AIR will not install your program to anybody. What is this signature?

Basically, by creating a digital signature for your program, you guarantee that the application you've made isn't going to harm the user's computer. The users trust you that you won't delete their personal files, steal their data and do other naughty stuff.

There are 2 ways to get a certificate. One - write it yourself. Two - buy it from a certificate authority. What are the differences?

If you sign your application yourself - its just you who says its safe. That probably won't convince a person who has never seen you personally before.



If you get your application signed by a certificate authority - its a big trusted company who says it is safe. That's more likely to earn the user's trust.



Here are some of the popular certificate authority companies: VeriSign, Digicert, Trustwave.

In the next tutorial we will create a simple AIR application using Flash and our own self-signed certificate.

Thanks for reading!
