Java Seed Encryption.

[syst3mboot]

Not sure if this is the right forum to ask this but can anyone help me.

Im trying to make an application or widget, something small, which firstly asks for the "seed". Afterwards messages will appear on the user's screen and if the seed is correct then they will be visible in propper english. Otherwise the letter would be scrambled.

So basically I want a way to encrypt messages to a custom seed and decrypt them at that same seed. Also would it be possible to make the encryption 128bit? or something that isn't decryptable? (of course without the seed)

Thank you

Anyone? here's an update.

So far I made the program be able to send messages, store them, and retrieve. All that's left is making it encrypt and decrypt based on a seed value.

Thanks

Have you looked at the Java Cryptography library?
I'd have thought that would be the first thing Google would have thrown up, which would have been faster than hoping for someone to be around here on a Sunday.
