Hi. I have a server running an application. (MobileIron). This applicastion takes control of the shell, so i do not have direct shell acess to the server, when i SSH, i go straight into the application itself.
The application has a web interface, to add certificates. There is a button to generate CSR. I fill in the information requested, and it outputs me a text file with: (i deleted the characters)
-----BEGIN CERTIFICATE REQUEST-----
-----END CERTIFICATE REQUEST-----
-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----
It tells me to upload this information my the CA, and it get the certificate.
The problem is, letscrypt does not let me upload this csr. I have tried using https://zerossl.com/, but it requires that i validate the server via HTTP (impossible, since i dont have access to the file system to include the verification files) or via DNS (also impossible, because it is handled by annother area of my company).
How do i generate the certificate by possessing only the Certificate Request and the Private Key???
