IX509SignatureInformation::get_PublicKeyAlgorithm method (certenroll.h)
The PublicKeyAlgorithm property specifies and retrieves an object identifier (OID) for the public key algorithm used in the GetSignatureAlgorithm method.
This property is read/write.
Syntax
HRESULT get_PublicKeyAlgorithm(
IObjectId **ppValue
);
Parameters
ppValue
Return value
None
Remarks
Unless you are retrieving a signature algorithm for a null-signed certificate request, you must set this property before calling the GetSignatureAlgorithm method. You must also set the HashAlgorithm property. You can also set the AlternateSignatureAlgorithm and NullSigned properties.
The PublicKeyAlgorithm property validates whether the OID you specify represents a public key algorithm. If the OID is valid, the property also clears the signature property cache.
