ActionScript 3 - PHP通过AMF（或其他）加密发送数据

Question

I need help with two things:

1. Advice on an encryption algorithm that I can use to encode data on the server, send it to AS3 client and decode it there. From what I read, Public - Private Key sound good.

2. An AS3 library that can encode and decode that is compatible with PHP's bcrypt (again, I read bcrypt is best for this kind of data transmission).

I'm not a security expert, I hope the question is clear and not clumsy.

EDIT: As suggested SSL is a great option, but at the moment I am looking for non-SSL ones.

Thank you.

Answer 1

What's your threat model? If you're only worried about people sniffing the data while it's on the wire, then use SSL. It'll be transparent to your app, and generally you only have to install a cert and change your URLs from http:// to https://

If your major threat is someone running a debugger on the app to catch the data, then you've got a massively bigger problem and will be highly unlikely to ever stop someone from "stealing" the data.
