Remote Files SE requires server certificate in HTTPS mode. The program may create certificate itself (default case) or use a third-party certificate. In the case when certificate is self-generated, web browsers show certificate error message each time a user connects to the server. This message may disappear with a third-party certificate.

If you want to create your own server certificate, you can read 'Certificate Signing Request (CSR) Generation Instructions' (for example). This page is written for Apache server, but steps are the same for Remote Files Server Edition too. When creating CSR, you will need OpenSSL binaries that can be downloaded from this page http://www.slproweb.com/products/Win32OpenSSL.html. Select Win32 OpenSSL v0.9.8k (7Mb with application files).

With CSR ready, you will need to request your own server certificate. You may contact Verisign or any other company that can offer the best terms. Also, many such companies provide test certificates.

When you get your own certificate, you may need to add some headings to it according to OpenSSL format. You may look at files mrf.key (private key) and mrf.crt (certificate) (located in the directory, where the program is installed) as examples. After that open administration window of Remote Files Server Edition, double click ‘Configuration…’ icon, when go to ‘Server Certificate’ page. Select ‘Use your own certificate’, than browse to certificate file, private key file (www.mydomain.com.key) and type password (pass phrase from step 1 ‘Certificate Signing Request (CSR) Generation Instructions’). Click ‘Save changes’. Restart server to make new certificate active.
