gpg-encryption

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

  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

and to decrypt, use:

  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.

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
