In Part 1, we saw how to generate your first keypair – A combination [...]
Welcome to Part 5 of GPG/PGP Key series.
What we will learn: This is one of the most important part of the entire series. We will learn how to manage our GPG keys – Backing it up, Restoring and Revoking (if need arises). Essentially this part should have come way before any other part of the [...]
Welcome to Part 4 of GPG/PGP Key series.
What we will learn: In last part we saw how to verify an encrypted sign (.sign) file to confirm if the files and their MD5SUMS were uploaded by the right person. In this part we will learn how to create those encrypted sign file so that your friends [...]
Welcome to Part 3 of GPG/PGP Key series.
What we will learn: In this part we will learn how to verify the encrypted signature file that is commonly found on web servers which offers download services.
Example: Suppose you decide to download the Debian’s NetInstaller CD from Debian HTTP servers. Now you will notice that there are [...]
Welcome to the Part 2 of GPG/PGP Key series.
What we learnt already: In Part 1 we saw how to generate our own unique GPG key in Linux and how to register your key to GPG keyservers.
What we will learn: In this part we will learn how to use those keys to send and receive encrypted [...]
Welcome to the Part 1 of GPG/PGP Key series.
What we will learn: In this part we will learn how to generate your first GPG/PGP key and also how to register our key to the GPG keyservers.

What’s all the HOOPLA about: I am glad to announce that we will soon be starting a series on GPG/PGP Key. Using GPG signature has become a standard practice for secure communication over Internet when sending emails, files, etc. to other people, especially in Open Source world. So it is very essential that we learn [...]
Purpose: This post is a follow-up of MD5SUM for ISO images post, in which we primarily learned how to generate MD5 checksums for your ISO images. In this post, we will learn about some of the available tools that you can use to verify those ISO images by running a check of their MD5 checksum [...]
Purpose: This blog entry will explain how to encrypt a shell script on your Linux or a Unix based system. Although there might be other ways to encrypt your shell script I found this one the most easiest to use. We will encrypt the script using the shc utility.
