Xorkeesign

Its mail extension enables users to digitally sign emails, helping recipients verify the sender’s identity and whether the message content has been altered. The service displays clear color indicators to communicate a message’s status, including when a sender is identified and the email is intact, when a signed message appears tampered with, or when a message is unsigned or its signature cannot be verified.

Users can sign emails in different ways. Organization-attested identity lets an authorized person in an organization confirm identity details, which may include a person’s role, qualifications, or other attributes. Alternatively, users can sign with a Digital Signature Certificate (DSC). xorkeesign offers guidance on how its protection works and how to install and use the extension with supported mail clients. The service is presented as simple and free to get started, with installation said to take about five minutes.
