I know this isn't a Mac/iPhone forum but since half of my problem lies in the Java world, I figure I might try here. I'll also be posting on Mac forums.
What I am looking for, is a way to encrypt a file using Java code, and then be able to put the file onto an iPhone and decrypt it there. I would also like to go the opposite way, but I assume if I can go one way, the other should be trivial. The file will be xml, but I'm not sure if that matters. Which, if any, of the Java encyption algorithms/methods can/should I use, that would make a file that could be decrypted on an iPhone.
I am quite familiar with Java, and have worked with Java encryption before, but I am totally new to iPhone development, and am by no mean a security and encryption expert. Any pointers in the right direction would be appreciated.
