HMAC-SHA-512 implemention for ActionScript

Question

As mentioned by the title, I would like to find an implementation for HMAC-SHA-512 written for ActionScript. I was able to find a library that provide HMAC-SHA-256 with other functions, however, I am looking for HMAC-SHA-512 specifically.

Thank you

Edit:

Or, since actionscript and javascript have the same origin, can some one port this javascript version into actionscript?

Edit 2:

I already ported the code from javascript to actionscript. The code can be found in one of the answers in this question Porting SHA-512 Javascript implementation to Actionscript

Answer 1

The implementation you link to doesn't seem to be using any features that aren't supported by ActionScript 3. Just surround the whole thing with public class SHA512 { }, and prefix the first five functions with public.

Edit: You will also need to convert function int64 to it's own class (or possibly use Number, though I'm not sure if you will lose precision for 64-bit integers).

Answer 2

Checkout this library: http://code.google.com/p/as3crypto/

Though only does: SHA-256,SHA-224,SHA-1,MD5, and MD2

So I guess that doesn't answer your question.

But best Crypto library for actionscript I've seen.

Answer 3

Just found all of SHA-2 (SHA-224, SHA-256, SHA-384, SHA-512) implemented at http://code.google.com/p/flame/. Also it provides HMAC implementation. Didn't try it yet but looks what you're looking for.
