The Mailfence SSL/TLS Certificate

When accessing mailfence.com, the transmission of information between your browsers and our servers in Brussels-Belgium is always encrypted and protected by SSL/TLS – for which each website has a (Public Key) Certificate that is verified by a trusted certificate authority.

Mailfence, a secure and private email suite has no American company in its SSL/TLS certification chain and the one which vouches for us is Buypass AS.

A modern browser should automatically check the validity of the Mailfence SSL/TLS certificate and alert you if it detects something untrustworthy. For security conscious users who want to manually check, our SSL/TLS certificate fingerprints/thumbprints (valid until 02/May/‎2020) are:

SHA1 fingerprint:

D1:8A:F3:FE:12:FB:E6:29:84:75:22:EB:83:F3:D2:8C:E4:67:F1:23

SHA-256 fingerprint:

29:27:34:55:A2:5C:B4:30:E9:63:AF:40:D0:BF:8F:00:E3:EF:B4:E6:5F:91:B2:23:2A:7D:6E:3F:95:83:56:48

If this matches what you see in your browser, then you know you are communicating with the real Mailfence website and using the correct public key to encrypt your sensitive information and only Mailfence can decrypt it.
