Enable Trust for Proficy Historian for a Self-signed Certificate

About this task

During Historian installation, a self-signed certificate is generated that you use with Historian web applications. A self-signed certificate is a certificate that is signed by itself rather than signed by a trusted authority. Therefore, a warning appears in the browser when connecting to a server that uses a self-signed certificate until it is permanently stored in your certificate store. This topic describes how to ensure that Google Chrome trusts the self-signed certificate.

Procedure

  1. Using Google Chrome, access the site to which you want to connect.
    A message appears to inform you that the certificate is not trusted by the computer or browser.
  2. Select Not Secure in the URL, and then select Certificate.
    The Certificate window appears.
  3. Select Certification Path, select the root certificate, and then select View Certificate.
    The Certificate window appears, displaying the General, Details, and Certification Path sections.
  4. Select Details, and then select Copy to File.
  5. Follow the on-screen instructions to save the certificate to a local file. Use the default format: DER encoded binary X.509 (.CER).
  6. Right-click the .CER file that you have exported, and select Install Certificate.
    The Certificate Import Wizard window appears.
  7. Select Trusted Root Certificate Authorities, and then select OK.
    Note: Do not let the wizard select the store for you.
    A Security Warning window may appear. If it does, ignore the message by selecting Yes. The certificate is installed.
  8. Restart the browser, and connect to the server.
  9. Open the URL authenticated by the certificate.
    If error messages do not appear, the certificate is successfully imported.
