Email Certificates (SMIME)

Email Encryption and Email Signing

Emails are sent as cleartext. Each node offers the possibility to attackers to intercept an email, so that the email can be read or modified. SMIME certificates ensure the validity, integrity and authenticity of your email's content. You can even protect the content by encrypting it, keeping it safe from uninvited readers.

SMIME stands for Secure Multipurpose Internet Mail Extensions, a globally recognized standard for the encryption of emails. Corresponding SMIME certificates consisting of a public one are required for using the SMIME encryption or signature and a private key. With the public key, the sender of an email encrypts the confidential content that the authorized recipient can then decrypt it again with his private key. Almost every email program is available for use Designed by SMIME as an independent standard and SMIME also works with Mac OS or Windows and also on mobile devices.
