Trust a self-signed SSL certificate

RapidMiner Studio comes with trusted root certificates from well known certificate authorities. This guide shows how to access a server that is either using a self-signed certificate or a certificate from an untrusted certificate authority. You will need to get at least hold of the root certificate that is used by the affected server in order to continue.

Intermediate certificates of the trust chain must be supplied by the server, or added to the cacerts folder.

Get the certificate

The root certificate for internal company systems should be supplied by your system administrator.

Please be aware that trusting a certificate of unknown source opens RapidMiner Studio to man-in-the-middle attacks and therefore these certificates should at best not be trusted, or at least only be kept as long as access to the affected server is needed.

Add public key certificates to RapidMiner Studio

Additional certificates are loaded on startup from the users home .RapidMiner/cacerts folder.

  1. Exit RapidMiner Studio
  2. Navigate to the .RapidMiner folder
    Windows
    Open the Explorer, type %HOME%/.RapidMiner into the address bar and press Enter
    macOS
    Open Finder, press Command+Shift+G, type ~/.RapidMiner and confirm with Enter.
    Linux
    Open your file manger, type ~/.RapidMiner into the address bar and press Enter.
  3. Create the cacerts folder if needed.
  4. Put the certificates (PEM or DER) into the cacerts folder.
  5. Start RapidMiner Studio

If successful, the .RapidMiner/rapidminer-studio.log will contain an entry similar to:

INFO: Loaded 1 certificate from company_cacert.cer
