Need portable encryption/decryption mechanism

I write a program that is used around the world.

Users need passwords to use certain features. I'm looking to implement Java encryption in the next release so that I can give them a password that decrypts into something meaningful to me.

Problem: I'm new to Java encryption. It appears that there's something built into the JDK. My questions:

- How portable is it around the world (i.e. Will it work in all countries?)

- Can anyone point me to good examples on how to use it?
