Encrypting Data using "tar" and "openssl" in Nix



The following shows an example of writing the contents of "tapetest" to tape:

        $ tar zcvf – tapetest | openssl des3 -salt  -k secretpassword | dd of=/dev/st0

     Reading the data back:


        $ dd if=/dev/st0 | openssl des3 -d -k "secretpassword" |tar xzf –


Or

$ tar –cvf * file.tar | openssl des3 -salt  -k secretpassword





till then.....
njoy the simplicity.......
