DataCrypt has been released! Currently beta but everything works.
You can download it here: https://toolslib.net/downloads/viewdownload/297-datacrypt/
An small note: I do not recommend entering very sensitive data (no, it does not collect any data nor inputs), because you can never be 100% sure that the encryption and encryption software is 100% secure. I am not responsible for any data damage, data theft, and so on.
