How to create a tar file encrypted with gpg in linux

First step is to create a script for the compression + encryption. You could to call it for instance: “encrypt”.

#!/bin/bash

  tput sc

  while [ -s $pass ] || [ $pass '!=' $pass2 ]; do

   read -s -p "Enter Passphrase: " pass;

   tput rc;

  read -s -p "Re-Enter Passphrase: " pass2;

   tput el1;

   tput rc;

  done;

  for file in $@; do

   tar -cf - $file | gpg -c --passphrase $pass > $file.gpg;

   srm $file;

  done

Next, if you want decrypt a file will be necessary to run another script defined as:

#!/bin/bash

  tput sc;

  while [ -s $pass ]; do

   read -s -p "Enter Passphrase: " pass;

   tput el1;

   tput rc;

  done;

  for file in $@; do

    tar -xf <(cat $file | gpg -d --passphrase $pass);

    if [ $? -eq 0 ]; then

      srm $file;

    else

      echo Failed to Decrypt;

      echo [password might be wrong];

    fi;

  done;

Finally, after the script definitions, you could run when you wish encrypt or decrypt a file:

encrypt filename

decrypt filename

Enjoy it!
