Welcome to the free S/MIME KeyServer

Use this service to deposit your own S/MIME email encryption certificate, and use it to obtain other people's email certificates.

If your correspondents have uploaded their cert, then you don't need to wait for them to send you a signed email message, you can retrieve one immediately.

Troubleshooting:
You sent an email, but it doesn't show up in the directory? The most popular reasons are:

• Your certificate is not trusted
• Please be patient. The email servers for kuix.de use greylisting for Spam protection purposes - it might take an hour until your email is routed to the directory - please try again one hour after sending.

Disclaimer:

• No guarantees, provided as is.
• For privacy reasons, this server never publishes the full list of known certificates or email addresses. In order to use the service of this S/MIME keyserver, you must already know the email address of your correspondent.
• No Logging! Besides the usual, temporary, rotating logfiles for e-mail server and web server, no other logs are produced. (This server will not keep permanent records of who requested certificates.)
