As3 TLS

Has anyone any idea about communicating in as3 with an server via TLS?

(I have on a server an mp3, and the server is HTTPS that requires an certificate and a key (TLS) and I need to get that mp3 on flash)

I found some classes (Crypto) but there the TLS it’s only partial implemented and support for client-side certificates is not implemented yet.

So maybe some of you worked with this and you know more things about it.

Thanks,
