Want to protect files from peeping eyes? Don't want to pay for software? Here is an app that will encrypt and decrypt files. -It's using the SHA512 algorithm to encrypt and decrypt. -The encrypted file will have the extension ".crypt". -You can optionally use a password to protect the file. I did not create this, I found a topic on it and went from there. Also I'm sure you could edit the source to use whatever algorithm you like. I have posted the [Source] and the app separately.
