Don’t send unencrypted data from Flash to PHP. I’ve prepared a class that will take a string and convert it to HEX SHA1. It’s fully compatible to compare with PHP sha1(), puts less than 1Kb filesize penalty to your project and is able to iterate through at least 50 calculations a second…
You can download the class file and an example FLA+Document class here (8Kb) (1038 downloads)
Modify, break, sell, copy, steal or improve. If you like it, tell me!

Awesome, will definitely come in useful in a few projects…
Wishing I had more projects to use this specific one with, I enjoy the PHP/Flash projects more…

I think your article is misleading. SHA1 creates a Hash and not an encrypted String that can be decrypted on the server-side. It surely is useful for passwords, where you compare the Hash sent by the user with the Hash in the Database. But you can’t use this to send encrypted data from flash to PHP.

Thank you! Pretty lightweight class and does just what i need for my AS 3.0 projects. Again, thank you!

I would like to ask you to provide the method to decrypt it?

I too would be very interested is an AS3 class to decript the string created by your encryption class.
