Encrypt Files Using GPG

Encrypt Files Using GPG – How To

Keeping your data secure is very important! Using GPG you can encrypt files easily and store them on a USB or on the cloud without worrying about prying eyes.

Step 1. Install GPG

Windows Users:

Download Gpa4win and during the installation make sure to check GPA as a component.


Step 2. Create a public/private key

Windows Users:

Open the program GPA and click keys > New key…

New key pub/priv

Linux Users:

$ gpg --gen-key
  • Select option (1) RSA and RSA (default)
  • Set the key size to 4096
  • Set the key to never expire option 0
  • Real name: Enter some name here
  • Email address: Enter email here (doesn’t have to be real)
  • Comment: Just hit enter
  • Create a passphrase

After this you’ll receive a message that states “We need to generate a lot of random bytes…”

Simply move your mouse around for a while and or use your computer normally. It will generate the key in a couple of minutes.

Step 3. Begin Encrypting

Windows Users:

Simply open up the Clipboard and selected files > *choose a file > encrypt

Linux Users:

Find your key’s id

$ gpg --list-keys 

gpg id

Mine is, for example, pub 4096R/35624565

And encrypt any file using:

# replace -r #number with your key id
$ gpg -r 35624565 -e encryptme.txt 

You’ll now have an encrypted file with a file extension of .gpg

encrypted text

And to decrypt:

# replace -r with your key id
$ gpg -r 35624565 -d encryptme.txt
