CRYPTUI_WIZ_DIGITAL_SIGN_EXTENDED_INFO structure (cryptuiapi.h)

  • Article

[The CRYPTUI_WIZ_DIGITAL_SIGN_EXTENDED_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_EXTENDED_INFO structure is used with the CRYPTUI_WIZ_DIGITAL_SIGN_INFO structure to contain extended information about a signature.

Syntax

typedef struct _CRYPTUI_WIZ_DIGITAL_SIGN_EXTENDED_INFO {
  DWORD             dwSize;
  DWORD             dwAttrFlags;
  LPCWSTR           pwszDescription;
  LPCWSTR           pwszMoreInfoLocation;
  LPCSTR            pszHashAlg;
  LPCWSTR           pwszSigningCertDisplayString;
  HCERTSTORE        hAdditionalCertStore;
  PCRYPT_ATTRIBUTES psAuthenticated;
  PCRYPT_ATTRIBUTES psUnauthenticated;
} CRYPTUI_WIZ_DIGITAL_SIGN_EXTENDED_INFO, *PCRYPTUI_WIZ_DIGITAL_SIGN_EXTENDED_INFO;

Members

dwSize

The size, in bytes, of the structure.

dwAttrFlags

A value that indicates the type of the signature. This can be one of the following values.

Value Meaning
CRYPTUI_WIZ_DIGITAL_SIGN_COMMERCIAL
 The signature is a commercial signature.
CRYPTUI_WIZ_DIGITAL_SIGN_INDIVIDUAL
 The signature is a personal signature.

pwszDescription

A pointer to a null-terminated Unicode string that contains the description of the subject of the signature.

pwszMoreInfoLocation

A pointer to a null-terminated Unicode string that contains the location from which to get more information about the file. This information will be displayed when the file is downloaded.

pszHashAlg

A pointer to a null-terminated ANSI string that contains the object identifier (OID) of the hash algorithm used for the signature. The default value is NULL, which indicates that the SHA-1 hash algorithm is used.

pwszSigningCertDisplayString

A pointer to a null-terminated Unicode string that contains the string displayed on the digital signature wizard page. The string should prompt the user to select a certificate for a specific purpose.

hAdditionalCertStore

A handle to an additional certificate store that will be added to the signature.

psAuthenticated

A pointer to a CRYPT_ATTRIBUTES structure that contains authenticated attributes supplied by the user.

psUnauthenticated

A pointer to a CRYPT_ATTRIBUTES structure that contains unauthenticated attributes supplied by the user.

Requirements

Requirement Value
Minimum supported client Windows XP [desktop apps only]
Minimum supported server Windows Server 2003 [desktop apps only]
