It works by attaching a\u00a0<\/span><strong><span data-preserver-spaces=\"true\">digital signature<\/span><\/strong><span data-preserver-spaces=\"true\"> to your emails, which serves two primary purposes:<\/span><\/p>\n<ol>\n<li><strong><span data-preserver-spaces=\"true\">Authentication:<\/span><\/strong><span data-preserver-spaces=\"true\"> It verifies that the email was sent by the claimed sender, not an imposter.<\/span><\/li>\n<li><strong><span data-preserver-spaces=\"true\">Integrity:<\/span><\/strong><span data-preserver-spaces=\"true\"> It ensures the email content has not been altered or tampered with during transmission.<\/span><\/li>\n<\/ol>\n<p><span data-preserver-spaces=\"true\">When you send an email with a digital signature, the recipient&#8217;s email client uses the sender&#8217;s\u00a0<\/span><strong><span data-preserver-spaces=\"true\">public key<\/span><\/strong><span data-preserver-spaces=\"true\"> (embedded in the certificate) to verify the signature.
