{{Scenario Task
|Scenario Task Format=Solution
|Scenario Task Parent=I want to be certain of the recipient's identity (and vice versa)
|Scenario Task Type=Impersonation
|Scenario Task Description=You've come to the right place! But all in due time: before you learn how to cryptographically sign your message, you first need to understand [[I want to learn about encrypting email | how email encryption works]] and generate a key pair, which is used to encrypt your messages, but also to digitally sign them.

By signing a message, you will be able to prove to the recipient that you are the actual author of the email (authenticity) and that the text has not been tampered with along its way from your computer to the recipient's inbox (integrity).

For more information, you can read the [http://www.bitcoinnotbombs.com/beginners-guide-to-pgp/ Digital Signatures] section on the Bitcoinbombs website and then a [https://securityinabox.org/en/guide/thunderbird/windows practical guide for your email client] from the Security in-a-box website.
