When request is received by emCA service, we will decrypt the request JSON Object with the same AES key that is shared with the client.
After successful decryption, request JSON object (Subject DN details, Key algorithm & Size, PFX password) + Username + Password + Profile Name + Subscriber ID + Application ID) is retrieved.
First the emCA service will validate username and password and check the IP Address used to make the request is registered with the same user
If request is registered with the same user, then we check if the certificate is already created for requested applicationId or not.
If certificate is already created for applicationId then return existing certificat
If certificate is not created for applicationId then we create certificate using the next step.
If it is same then (signature data) is validated by checking whether user info i.e. (Subject DN details, key algorithm & size, pfx password) is signed by same pfx which is registered for the specific user.
If validation fails at any point in processing the request, the emCA service will throw error/failure message.
Response Parameters
