S/MIME Zertifikate

Every email is vulnerable, theoretically. The path of an email through the Internet is long, even if the speed of transmission often makes you forget. Emails can be intercepted, read or even modified during transport. At least if they are sent unencrypted. The consequences can be devastating: financial damage, data loss or loss of image threaten all those who exchange unencrypted emails. In addition, unencrypted emails are already no longer compatible with data protection – also with regard to the GDPR.

One way to enable secure email communication and send information confidentially and securely is PKI-based email encryption and signature. PKI stands for Public Key Infrastructure, and the most common standard for such encryption used by government agencies and companies is S/MIME (Secure/Multipurpose Internet Mail Extensions).
