Encrypting and signing e-mail
E-mail security is based on a set of cryptographic algorithms ensuring both that only the holder of a specific key can read a message (encryption) and prove the message have not been changed while in transit (signing).
The goal of this lab is to familiarize you with e-mail security using the well known tool GnuPGP, also known as GPG. GPG is a free implementation of the OpenGPG standard, which is based on the commercial tool PGP.
