All
Right now, our backups tapes are written with ...
tar -cvf /dev/st0 ./$Path >> $TOC
... and I am thinking of adding some kind of encryption to the routine.  
Is there anything simple, or am I looking at writing something to use 
the likes of blowfish?  Thank you in advance for any help you may be 
able to offer.
Regards
Fred James
