encoding within an applet can it be secure?

Hello,

I have an applet which should do this
1) collect data
2) encode the data
3) send it over the net
Can this be secure?
Is there a package, which can make this in a way, that nobody can crack the data bei anayzing the applet code?

Thank you
Frodo

Have a look at Hushmail( http://www.hushmail.com/ ). These guys have done exactly this - as a mail client applet. They offer secure mail - 1024 bit encryption. ( to Hushmail addresses, however... )

The applet's code will still need to be obfuscated, though.

Hope that helps...
