Very simple utility to encrypt and decrypt text via a symmetric key encryption algorithm. It allows users (who both have the app installed) to type or paste text and encrypt it/decrypt it, in any language. A default key (shared secret) is provided and used as part of the encryption algorithm, but it can be changed to a preferred custom value. The encryption or decryption results can be copied to the clipboard for further use.

It is a fun app to demonstrate encrypting capabilities, but can be useful for protecting confidential messages.
