xorkeesign Webmail
xorkeesign Webmail is a Chrome extension developed by Odyssey Technologies Ltd. It enables users to digitally sign and verify emails in popular webmail services. This extension utilizes the versatile xorkee infrastructure, which is a superset of PKI, to authenticate emails sent by users and verify the authenticity of received emails.
The extension seamlessly integrates with various popular webmail clients, offering users the option to bind their personal key with their email ID through xorkeesign. When users access supported mail interfaces, xorkeesign prompts them to digitally sign emails before sending, providing choices to sign the mail body, attachments, or both, in standard PKI-CMS format (RFC #5652).
