Dear Support Team,

How to decrypt a .gpg file using script or command line based? 

I am looking for a script to automate the task of decrypting the file on daily basis.

Thanks in advance.

From the command line

Let's say you have a file, ~/Documents/important.docx, that you want to password protect. Using gpg, you would do the following.

1. Open a terminal window.
2. Change to the ~/Documents directory with the command cd ~/Documents.
3. Encrypt the file with the command gpg -c important.docx.
4. Enter a unique password for the file and hit Enter.
5. Verify the newly typed password by typing it again and hitting Enter.

You should now see the file important.docx.gpg in the ~/Documents folder. To decrypt that file, do the following.

1. Open a terminal window.
2. Change to the ~/Documents directory with the command cd ~/Documents.
3. Decrypt the file with the command gpg important.dox.gpg.
4. When prompted, enter the decryption password you created when encrypting the file.

You could send that file to a recipient and, as long as they have gpg installed, they can decrypt the file with the password you used for encryption. If they are a Windows user, they can always install Gpg4win.
