ClientCertificateInstall CSP

  • Artikel

Logo of Windows Insider.

Important

This CSP contains some settings that are under development and only applicable for Windows Insider Preview builds. These settings are subject to change and may have dependencies on other features or services in preview.

The ClientCertificateInstall configuration service provider enables the enterprise to install client certificates. A client certificate has a unique ID, which is the [UniqueID] for this configuration. Each client certificate must have different UniqueIDs for the SCEP enrollment request.

Note

For PFX certificate installation and SCEP installation, the SyncML commands must be wrapped in atomic commands to ensure that enrollment execution isn't triggered until all settings are configured. The Enroll command must be the last item in the atomic block.

The following list shows the ClientCertificateInstall configuration service provider nodes:

./Device/Vendor/MSFT/ClientCertificateInstall/PFXCertInstall/{UniqueID}/PFXCertBlob

Required.

CRYPT_DATA_BLOB structure that contains a PFX packet with the exported and encrypted certificates and keys. Add on this node will trigger the addition to the PFX certificate. This requires that all the other nodes under UniqueID that are parameters for PFX installation (Container Name, KeyLocation, CertPassword, fKeyExportable) are present before this is called. This will also set the Status node to the current Status of the operation.

If Add is called on this node and a blob already exists, it will fail. If Replace is called on this node, the certificates will be overwritten.

If Add is called on this node for a new PFX, the certificate will be added. If Replace is called on this node when it doesn't exist, this will fail.

In other words, using Replace or Add will result in the effect of either overwriting the old certificate or adding a new certificate

./User/Vendor/MSFT/ClientCertificateInstall/PFXCertInstall/{UniqueID}/PFXCertBlob

Required.

CRYPT_DATA_BLOB structure that contains a PFX packet with the exported and encrypted certificates and keys. Add on this node will trigger the addition to the PFX certificate. This requires that all the other nodes under UniqueID that are parameters for PFX installation (Container Name, KeyLocation, CertPassword, fKeyExportable) are present before this is called. This will also set the Status node to the current Status of the operation.

If Add is called on this node and a blob already exists, it will fail. If Replace is called on this node, the certificates will be overwritten.

If Add is called on this node for a new PFX, the certificate will be added. If Replace is called on this node when it doesn't exist, this will fail.

In other words, using Replace or Add will result in the effect of either overwriting the old certificate or adding a new certificate
