3.2.1.4.3.2.39 PropID = 0x00000027 (CR_PROP_CACERTVERSION) "CA Signing Certificates Revisions"

  • Artigo

The client has requested the revisions on the CA signing certificate. If the server implements the Signing_Cert table, it MUST return a ULONG array that identifies the revisions to its signing certificates as specified as follows. Otherwise, the server MUST return an empty CERTTRANSBLOB structure.

The CA MUST return the array in a CERTTRANSBLOB (section 2.2.2.2) structure. Each ULONG value in the returned array MUST contain version information for a signing certificate in little-endian format. The upper 16 bits MUST contain a zero-based key index, and the lower 16 MUST contain a zero-based certificate index.

Example: The CA has renewed its certificates in the following manner:

  •  Certificate_0 contains the original key.

  •  Certificate_1 is created by renewing Certificate_0 with a new key.

  •  Certificate_2 is created by renewing Certificate_1 with the key used to create Certificate_1.

  •  Certificate_3 is created by renewing Certificate_2 with the key used to create Certificate_1.

  •  Certificate_4 is created by renewing Certificate_3 with the key used to create Certificate_1.

  •  Certificate_5 is created by renewing Certificate_4 with a new key.

  •  Certificate_6 is created by renewing Certificate_5 with the key used to create Certificate_5.

  •  Certificate_7 is created by renewing Certificate_6 with the key used to create Certificate_5.

  •  Certificate_8 is created by renewing Certificate_7 with a new key.

This renewal pattern leads to the following ULONG array.
