Intelligent Sandbox allows you to generate a certificate signing request (CSR) from the web interface.
When you generate a CSR , Intelligent Sandbox attaches the key to the CSR. This is because the key for the CSR is with Intelligent Sandbox.
To generate a CSR, you need to enter your organization details, and the key size. You can then generate your CSR, export it, and submit it to a certificate signing authority to get it signed.
