Connecting the SSL certificate

SSL certificate is a digital document that confirms the authenticity of the website and ensures the security of the user's personal data. When using an SSL certificate, data is transmitted to the server via a secure protocol. An SSL certificate consists of a public key and a private key, and may also include a chain of certificates.

If the certificate was not specified when installing the platform, a self-signed SSL certificate will be connected to the platform. When opening the platform's web interface, a warning about a possible security threat will appear in the browser. To prevent this warning from appearing, connect an SSL certificate signed by a certificate authority to the platform.

You can purchase a certificate from any certificate issuing service or get a free one from Let's Encrypt. You can get a Let's Encrypt certificate through the platform interface. The platform interacts with Let's Encrypt using the acme.sh script.

A Let's Encrypt certificate is valid for 90 days. and is automatically reissued before the expiration date. If you ordered a certificate through the platform interface, the platform will automatically start the renewal process before the certificate expires.
