Enable SSL on MATLAB Web App Server

SSL (Secure Sockets Layer) is a networking protocol that encrypts data sent between clients and servers. On MATLAB® Web App Server™, SSL setup requires a certificate and private key pair.

Restrictions

The certificate must conform to the following restrictions:

  • MATLAB Web App Server only supports the .pem SSL certificate format.

  • SSL keys must be private and must be at least 2048 bits and up to 4096 bits in length (support for 4096-bit keys was introduced in R2023a Update 3).

  • Intermediate certificates are not supported by the server.

The private key must conform to the following restrictions:

  • The private key must not be password protected

  • The private key file must be in a location that is readable only by the server account.

    A convenient location to store the certificate file and private key file is the webapps_private folder. For the location of the webapps_private folder, see Authentication.

Enable SSL

To enable Secure Sockets Layer (SSL) on the server:

  1. Obtain a certificate file and private key file for the server from a certificate authority and place these files in a location accessible to the MATLAB Web App Server.

  2. At the terminal, navigate to the folder containing MATLAB Web App Server command-line scripts.

    Operating SystemDefault Location of Command-Line Scripts

    Windows® (Administrator)

    C:\Program Files\MATLAB\MATLAB Web App Server\R2025a\script

    Linux® (sudo)

    /usr/local/MATLAB/MATLAB_Web_App_Server/R2025a/script

    macOS (Intel® processor) (sudo)

    /Applications/MATLAB/MATLAB_Web_App_Server/R2025a/script

  3. At the terminal, type:

    webapps-config set ssl_certificate_file <path to certificate file>

  4. At the terminal, type:

    webapps-config set ssl_private_key_file <path to private key file>

  5. At the terminal, type:

    webapps-config set ssl_enabled true

  6. Restart the server.
