Secure Tar (star) doesn't create encrypted tape archives (tar files)
yet, but it can encrypt/decrypt files only using multiple blocksizes,
and keysizes using the AES algorithm Rijndael. Once the standalone app
is stable, then it will be encorporated with tar. The encryption is
exported under exemption TSU 740.13.
