3.2.1.4.3.2.7 PropID = 0x00000007 (CR_PROP_SANITIZEDCANAME) "Sanitized CA Name"

The client has requested the common name of the certification authority (CA) in the sanitized form. The name of the CA returned in this property is taken from the CN attribute of the Subject field in the CA signing certificate, and is then sanitized. More information about the Windows sanitizing name algorithm is specified in section 1.3.2.5.

The CA MUST return a sanitized value (as specified in section 3.1.1.4.1.1) of the CN attribute of the Subject field in the CA signing certificate found in the Signing_Cert_Certificate column in the indexed row of the Signing_Cert table specified by the PropIndex parameter as a [UNICODE] string, through a CERTTRANSBLOB structure.

Marshaling rules for CERTTRANSBLOB are specified in section 2.2.2.2.
