You should encrypt very sensitive files with the program bcrypt. Bcrypt uses the secure Blowfish-algorithm.
Open a shell and enter:
bcrypt /MyDirectory/MyFile
Then you are asked a passwort (at least eight characters long; you can abort bcrypt with "Ctrl" + "C"). Bcrypt encrypts your file and appends the extension bfe to the file. The original file is deleted automatically.
If you want to encrypt more than one file or a complete directory you should create an archive-file. Start the program "Menu | Utilities | Xarchive archiver". Afterwards you encrypt the archive-file.
Note that bcrypt deletes the original file automatically. You can't recover the file. If you don't want to delete the file start bcrypt with the option -r:
bcrypt -r /MyDirectory/MyFile
If you want to decrypt the file start bcrypt again:
