SSL certificate requirements

To ensure secure communication and enable HTTPS for your VisualDrive Server, you need to use a valid and trusted SSL web server certificate.

This document outlines the essential requirements for this certificate and explains the impact of certificate-related issues.

Enabling HTTPS can be skipped in a test environment. In a test environment, VisualDrive Server can be configured to allow access over plain HTTP.

Requirements

The used SSL certificate needs to meet the following requirements:

RequirementDescription
Certificate storageCertificate must be available through the Local Machine certificate store on the computer with VisualDrive Server.
Private keyCertificate must have an associated private key.
Issuer trustCertificate must be valid and issued by a trusted Certification Authority (CA).
HostnameHostname in the certificate must match the Server URL configured in VisualDrive Server.
Key Usage (KU)Key usage must include Digital Signature for signing the TLS handshake data.
Extended Key Usage (EKU)Extended key usage must include the Server Authentication purpose.

Impact of certificate issues

If there is a certificate issue (for instance, if the certificate is expired, self-signed, improperly configured, or issued by an untrusted Certificate Authority):

  • Users will be unable to sync their drives via the OneDrive app.
  • Users may see error messages related to certificate trust, connection issues, or sync failures.

The OneDrive sync app does not allow ignoring certificate errors.
