How secure is it to post login information from flash to ASP?

Hello,

I have yet another question that has been bothering me for some time, I am posting login information to my .asp file (username and password), just a regular post, once it gets to asp it gets encrypted and it should be safe from there on but going from flash to asp, I dont know much about security there, please let me know how secure it is and if its not secure at all what can I do to make it more secure?
(does https certificate take care of that? if yes then, are there other more affordable options?)

Thanks in advance..

 

Alright, sounds like I need an https certificate to make this secure..
I wish those things didnt cost as much
Oh well hopefully it will pay itself out in time

Thanks for the response
