Purpose of szOID_ENROLLMENT_CSP_PROVIDER and szOID_REQUEST_CLIENT_INFO RRS feed

  • Question

  • Hi,

    How is the information in the PKCS10 attributes szOID_ENROLLMENT_CSP_PROVIDER [1] and szOID_REQUEST_CLIENT_INFO [2] used by Microsoft's CA?

    I noticed that these attributes are present in CSRs generated by Microsoft's CA and I have not seen them before.

  • Hi Bastian:

    The CA semantics for these OID's are described in MS-WCCE section " 3.2.1.4.2.1.4.1.1 New Certificate Request Using PKCS #10 Request Format" ( https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-wcce/0f92ce74-f921-41d8-8a1b-a6814d4e7fa7 )

    These OID's are used in Health Certificate Enrollment Protocol (MS-HCEP). If you have any specific question on these documents, please feel free to contact us at dochelp at microsoft dot com.

    Please let me know if this does not answer your question.
