CRYPTUI_WIZ_DIGITAL_SIGN_INFO structure (cryptuiapi.h)

  • Article

[The CRYPTUI_WIZ_DIGITAL_SIGN_INFO structure is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

The CRYPTUI_WIZ_DIGITAL_SIGN_INFO structure contains information about digital signing. This structure is used by the CryptUIWizDigitalSign function.

Syntax

typedef struct _CRYPTUI_WIZ_DIGITAL_SIGN_INFO {
  DWORD                                    dwSize;
  DWORD                                    dwSubjectChoice;
  union {
    LPCWSTR                              pwszFileName;
    PCCRYPTUI_WIZ_DIGITAL_SIGN_BLOB_INFO pSignBlobInfo;
  };
  DWORD                                    dwSigningCertChoice;
  union {
    PCCERT_CONTEXT                           pSigningCertContext;
    PCCRYPTUI_WIZ_DIGITAL_SIGN_STORE_INFO    pSigningCertStore;
    PCCRYPTUI_WIZ_DIGITAL_SIGN_CERT_PVK_INFO pSigningCertPvkInfo;
  };
  LPCWSTR                                  pwszTimestampURL;
  DWORD                                    dwAdditionalCertChoice;
  PCCRYPTUI_WIZ_DIGITAL_SIGN_EXTENDED_INFO pSignExtInfo;
} CRYPTUI_WIZ_DIGITAL_SIGN_INFO, *PCRYPTUI_WIZ_DIGITAL_SIGN_INFO;

Members

dwSize

The size, in bytes, of the structure.

dwSubjectChoice

A value that indicates the entity that is to be signed. This member is required if CRYPTUI_WIZ_NO_UI is specified in the dwFlags parameter of the CryptUIWizDigitalSign function. This can be one of the following values.

Value Meaning
CRYPTUI_WIZ_DIGITAL_SIGN_SUBJECT_BLOB
 The memory BLOB specified by the pSignBlobInfo member is to be signed.
CRYPTUI_WIZ_DIGITAL_SIGN_SUBJECT_FILE
 The file specified by the pwszFileName member is to be signed.
0
 The user will be prompted for a file to sign.

pwszFileName

A pointer to a null-terminated Unicode string that contains the path and file name of the file to sign. This member is used if CRYPTUI_WIZ_DIGITAL_SIGN_SUBJECT_FILE is specified for the dwSubjectChoice member.

pSignBlobInfo

A pointer to a CRYPTUI_WIZ_DIGITAL_SIGN_BLOB_INFO structure that contains the BLOB to sign. This member is used if CRYPTUI_WIZ_DIGITAL_SIGN_SUBJECT_BLOB is specified for the dwSubjectChoice member.

dwSigningCertChoice

A value that specifies the location of the certificate that is used to sign the entity. The default value is zero. This can be one of the following values.

Note  If CRYPTUI_WIZ_NO_UI is specified in the dwFlags parameter of the CryptUIWizDigitalSign function, this value must be either CRYPTUI_WIZ_DIGITAL_SIGN_CERT or CRYPTUI_WIZ_DIGITAL_SIGN_PVK.
 
Value Meaning
CRYPTUI_WIZ_DIGITAL_SIGN_CERT
 The certificate is contained in the CERT_CONTEXT structure pointed to by the pSigningCertContext member.
CRYPTUI_WIZ_DIGITAL_SIGN_STORE
 The certificate is contained in the certificate store contained in the CRYPTUI_WIZ_DIGITAL_SIGN_STORE_INFO structure pointed to by the pSigningCertStore member.
CRYPTUI_WIZ_DIGITAL_SIGN_PVK
 The certificate is contained in the PVK file contained in the CRYPTUI_WIZ_DIGITAL_SIGN_CERT_PVK_INFO structure pointed to by the pSigningCertPvkInfo member.
0
 The certificates in the My store are used.

pSigningCertContext

A pointer to a CERT_CONTEXT structure that contains the certificate to use to sign the entity. This member is used if CRYPTUI_WIZ_DIGITAL_SIGN_CERT is specified for the dwSigningCertChoice member.

pSigningCertStore

A pointer to a CRYPTUI_WIZ_DIGITAL_SIGN_STORE_INFO structure that contains the certificate to use to sign the entity. This member is used if CRYPTUI_WIZ_DIGITAL_SIGN_STORE is specified for the dwSigningCertChoice member.

pSigningCertPvkInfo

A pointer to a CRYPTUI_WIZ_DIGITAL_SIGN_CERT_PVK_INFO structure that contains the certificate to use to sign the entity. This member is used if CRYPTUI_WIZ_DIGITAL_SIGN_PVK is specified for the dwSigningCertChoice member.

pwszTimestampURL

A pointer to a null-terminated Unicode string that contains the URL for the time stamp.

dwAdditionalCertChoice

A value that indicates whether additional certificates will be included in the signature. The default value is zero. This can be one of the following values.

Value Meaning
CRYPTUI_WIZ_DIGITAL_SIGN_ADD_CHAIN
 The entire certificate chain will be included in the signature.
CRYPTUI_WIZ_DIGITAL_SIGN_ADD_CHAIN_NO_ROOT
 All certificates in the certificate chain except the root will be included in the signature.
0
 No additional certificates will be included in the signature.

pSignExtInfo

A pointer to a CRYPTUI_WIZ_DIGITAL_SIGN_EXTENDED_INFO structure that contains extended information about the signature.
