fSekrit is a small application for keeping encrypted notes. The real advantage is that notes are truly self-contained; the editor program and your note are merged together into a tiny self-contained program file, removing the need to install a special application to view your data. This makes it ideal for keeping encrypted notes on, for example, USB flash drives. Another advantage of using it is that your un-encrypted data is never stored on your harddisk. With a traditional encryption utility you would have to decrypt your file to disk, view or edit it, and then re-encrypt it, and unless you use secure file wiping tools, it would be a trivial matter for someone to to retrieve your un-encrypted data, even though you have deleted it. This can't be done with fSekrit, though, since it never stores your un-encrypted data on disk. It uses very strong encryption (256-bit AES/Rijndael in CBC mode) to ensure that your data is never at risk.
