IX509CertificateRequestCertificate::get_SerialNumber method (certenroll.h)

  • Article

The SerialNumber property specifies and retrieves the certificate serial number. The serial number is contained in a byte array encoded by using Distinguished Encoding Rules (DER) as defined by the Abstract Syntax Notation One (ASN.1) standard. The DER-encoded byte array is represented by a string that is either a pure binary sequence or is Unicode encoded.

This property is read/write.

Syntax

HRESULT get_SerialNumber(
  EncodingType Encoding,
  BSTR         *pValue
);

Parameters

Encoding

pValue

Return value

None

Remarks

After calling Encode, the default value is a GUID with a high-order nibble that is not zero (to ensure that the hexadecimal representation of the serial number has an even number of digits). The high-order nibble is in the range 1 to 7. You must initialize the request object before calling this property. For more information, see any of the following methods:
