Email Signing Certificate

Publically Trusted Secure Email Certificates

Entrust Secure Email Certificates are publicly trusted S/MIME certificates that enable individuals or organizations to encrypt and digitally sign emails and other documents.

How do S/MIME Email Certificates Work?

Entrust Secure Email Certificates, also known as S/MIME (Secure / Multipurpose Internet Mail Extensions) Certificates, provide the strongest levels of confidentiality and security for your electronic communications by allowing you to digitally sign and encrypt your mail and attachments. Encryption means that only your intended recipient will be able to read message, while digitally signing it allows them to confirm and verify that you sent the message and it was not tampered with.
