#+title: gpg-encryption
#+filetags: :linux:security:gpg:

If you want to encrypt a file, use the following command:

#+begin_src bash

  gpg -c file.txt

  # options include :
  # gpg -c file.txt : for symmetric encryption
  # gpg -d file.txt.gpg : to decrypt the file
  # gpg --batch -c --passphrase mypassphrase file.txt : accepts passphrase right from command line  

#+end_src

and to decrypt, use:

#+begin_src bash

  gpg -d file.txt

  # You have to wait 10 minutes before you can get prompted for a password, before this, it will
  # decrypt without the passphrase.

#+end_src

gpg --batch -c --passphrase Shakkal123! passwords.md

gpg --batch -d --passphrase Shakkal123! passwords.md.gpg

gpg --batch --output passwords.md -d --passphrase Shakkal123! passwords.md.gpg
