If you just want to encrypt a tar file, you can do this.
tar cvf - ./$Path | openssl bf -e -pass pass:xyzzy > /dev/st0 >> $TOC
To decrypt, do this.
openssl bf -d < /dev/st0 | tar xf - $files
enter bf-cbc decryption password: xyzzy
Look at the openssl and bf man pages for details.
But think carefully about password management. The scheme above
uses a fixed password. A regularly changing one would be better.
A password that isn't stored in a script would be better yet.
