How to easily encrypt a file with GPG on Linux

Jan 122013

Today i return to the topic of encryption and security and in particular I’ll show how to simply encrypt a file with GnuPG, this can be really usefull to encrypt a single file where you have your passwords or some personal information that you want to keep safer.

GNU Privacy Guard (GnuPG or GPG) is a GPL Licensed alternative to the PGP suite of cryptographic software. GnuPG is compliant with RFC 4880, which is the current IETF standards track specification of OpenPGP. Current versions of PGP (and Veridis’ Filecrypt) are interoperable with GnuPG and other OpenPGP-compliant systems.

This software is frequently integrated with mail client so it can sign, crypt or do both actions on the mail you send and receive, and now we’ll see how to use it on the command line to encrypt a file.

Today I’ll present you some good solutions to save your home directory, this is the reason I’ve called this type of backup “lightweight”, the goal is not to restore the full operating system, just all the information you have in your /home directory, that for desktop usually means save all important information of your computer.

Naturally on a server this approach is not so useful because you want to save your websites, databases and all programs configurations, so don’t use this approach on a server.
