AS3WebSocket library SHA1 error

Question

I am trying to use https://github.com/Worlize/AS3WebSocket library. When I create Flex project everything ok, but when I create AS3 project it can't connect to a websocket server. Function SHA1.hashToBase64 (adobe.crypto library) inside Websocket class throws error:

Any ideas why?

Answer 1

I downloaded the as3corelib.swc being used by that project, and ran the following code.

SHA1.hashToBase64('k9NwkeRGtpHKwr+kcSk29tHaAbs=');

In addition to your output, which basically says Flash Player threw an error trying to construct a new Base64Encoder object, I got the following output.

VerifyError: Error #1014: Class mx.utils::Base64Encoder could not be found.

It seems to be a known issue with as3corelib that was never resolved.

However, this dependency is also open source, so I just downloaded Base64Encoder.as, and added it to my project. After this, the code compiled fine. This should work for your project, as well.
