All versions of Venafi Trust Protection Platform.
Trust Protection Platform (TPP) does not currently fully support Code Signing Certificates. TPP is able have code signing certificates imported to the system and monitor those certificates. TPP does't currently support doing automated enrollment or provisioning of code signing certificates.
Code signing certificates are similar to SSL certificates but have additional options that are unique to code signing. These options are not currently supported by TPP at this time and so we are not able to create Certificate Signing Requests for code signing certificates. Code Signing Certificates are also usually valid for extended periods because the certificate is for software that will be in production for long periods of time.
