I'm developing a secure flex application in order to mantain user and password catalog, i need to create SSL Transport channel and a non-repudiation request mechanism. I already review that i could achieve first with HTTP Service for SSL and the second with XML Digital Signature but only i find java and .NET APIs for last. Is there an equivalent flex mechanism (or Action Script) to achieve XML Digital Signature?
Thanks in advance.
Some time ago I was researching for this but never fallowed through it... I can only give some hints I've found during the process, hope they help:
http://code.google.com/p/as3crypto/ (this is a lib that handles a lot of encryption methods including public encryption)
