How To Lock Secret Files With GPG

In this guide, I will explain the options at your disposal for encrypting files using open-source software on a Linux, Mac, or Windows computer. You can then transport this digital information across distance and time, to yourself or others.

The program “GNU Privacy Guard” (GPG) an open-source version of PGP (Pretty Good Privacy), allows:

  1. Encryption using a password.
  2. Secret messaging using public/private key cryptography
  3. Message/Data authentication (using digital signatures and verification)
  4. Private key authentication (used in Bitcoin)
