The registrars manage EPP certificates. Our registrars themselves update their certificates for .se and .nu. To complete the task, you need to log in to your registrar account here on the registrar website.
Client certificates are a requirement, and our EPP servers require SSL connections with certificates.
Upload certificates by logging into the registrar account and making the desired changes under Users - EPP.
Note that the certificate's common name must be unique for each connecting user. (This identification is then used to limit the number of connections to the server to four per user.)
We accept all types of certificates and validate them solely based on their expiration dates.
