The CryptoKeyStorage class provides access to key stores of various types.

Syntax

CryptoKeyStorage

Remarks

CryptoKeyStorage allows you to load and access cryptographic keys stored on different media, such as memory buffers, files, operating system, and hardware security modules.

To access keys stored on certain type of media, start with the Open method. Provide the location of your certificates via a uniform URI-like specifier. Once the storage has been opened, you can access the certificates contained in it via the Keys property.

 
 Copy
  KeyStorage.Open("pkcs11://user:12345@localhost/C:/Windows/system32/asepkcs.dll?slot=0");

Iterate over the keys by using the Keys property, or use filtering facilities provided by the Select method. You can add keys to the storage with the ImportBytes, ImportFromFile, and ImportPinned methods. In the latter case please assign the key object to be imported to the PinnedKey property.

Use CreateNew method to create a new storage. Note that not all storage kinds can be created.

 
 Copy
  KeyStorage.CreateNew("file", StorageFile);

When you have finished working with the certificate storage, close it with the Close method.

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* secureblackbox_cryptokeystorage_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CreateNew Method (CryptoKeyStorage Class)

Creates a new storage.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CreateNew(const char* lpszStorageLocation, const char* lpszStorageID);

Unicode (Windows)
INT CreateNew(LPCWSTR lpszStorageLocation, LPCWSTR lpszStorageID);

int secureblackbox_cryptokeystorage_createnew(void* lpObj, const char* lpszStorageLocation, const char* lpszStorageID);

int CreateNew(const QString& qsStorageLocation, const QString& qsStorageID);

Remarks

Use this method to create new key storage.

StorageLocation specifies where the new storage should be created, and StorageID contains a unique storage identifier.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

char* secureblackbox_cryptokeystorage_doaction(void* lpObj, const char* lpszActionID, const char* lpszActionParams);

QString DoAction(const QString& qsActionID, const QString& qsActionParams);

Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

Common ActionIDs:

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetStorageProperty Method (CryptoKeyStorage Class)

Sets the value of a custom key storage property.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SetStorageProperty(const char* lpszPropName, const char* lpszPropValue);

Unicode (Windows)
INT SetStorageProperty(LPCWSTR lpszPropName, LPCWSTR lpszPropValue);

int secureblackbox_cryptokeystorage_setstorageproperty(void* lpObj, const char* lpszPropName, const char* lpszPropValue);

int SetStorageProperty(const QString& qsPropName, const QString& qsPropValue);

Remarks

This method, together with GetStorageProperty, provides an extensible way of managing the certificate storage's settings that are not available through the primary properties of the component. The list of settings may be extended in future, in response to emergence of new storage variants and recognition of non-obvious storage usage scenarios.

Currently no custom properties are available for this component.

Error Event (CryptoKeyStorage Class)

Fires when an errors happens during a key storage operation.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireError(CryptoKeyStorageErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} CryptoKeyStorageErrorEventParams;


Unicode (Windows)
virtual INT FireError(CryptoKeyStorageErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  INT reserved;
} CryptoKeyStorageErrorEventParams;

#define EID_CRYPTOKEYSTORAGE_ERROR 1

virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);

class CryptoKeyStorageErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(CryptoKeyStorageErrorEventParams *e);

// Or, subclass CryptoKeyStorage and override this emitter function.
virtual int FireError(CryptoKeyStorageErrorEventParams *e) {...}

Remarks

This event reports an exceptional situation during a key storage operation.

ErrorCode contains an error code and Description contains a textual description of the error.

Notification Event (CryptoKeyStorage Class)

This event notifies the application about an underlying control flow event.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireNotification(CryptoKeyStorageNotificationEventParams *e);

typedef struct {
  const char *EventID;
  const char *EventParam;
  int reserved;
} CryptoKeyStorageNotificationEventParams;


Unicode (Windows)
virtual INT FireNotification(CryptoKeyStorageNotificationEventParams *e);

typedef struct {
  LPCWSTR EventID;
  LPCWSTR EventParam;
  INT reserved;
} CryptoKeyStorageNotificationEventParams;

#define EID_CRYPTOKEYSTORAGE_NOTIFICATION 2

virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);

class CryptoKeyStorageNotificationEventParams {
public:
  const QString &EventID();

  const QString &EventParam();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Notification(CryptoKeyStorageNotificationEventParams *e);

// Or, subclass CryptoKeyStorage and override this emitter function.
virtual int FireNotification(CryptoKeyStorageNotificationEventParams *e) {...}

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

PasswordNeeded Event (CryptoKeyStorage Class)

This event is fired when a decryption password is needed.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FirePasswordNeeded(CryptoKeyStoragePasswordNeededEventParams *e);

typedef struct {
  const char *NeededFor;
  char *Password;
  int Cancel;
  int reserved;
} CryptoKeyStoragePasswordNeededEventParams;


Unicode (Windows)
virtual INT FirePasswordNeeded(CryptoKeyStoragePasswordNeededEventParams *e);

typedef struct {
  LPCWSTR NeededFor;
  LPWSTR Password;
  BOOL Cancel;
  INT reserved;
} CryptoKeyStoragePasswordNeededEventParams;

#define EID_CRYPTOKEYSTORAGE_PASSWORDNEEDED 3

virtual INT SECUREBLACKBOX_CALL FirePasswordNeeded(LPSTR &lpszNeededFor, LPSTR &lpszPassword, BOOL &bCancel);

class CryptoKeyStoragePasswordNeededEventParams {
public:
  const QString &NeededFor();

  const QString &Password();
  void SetPassword(const QString &qsPassword);

  bool Cancel();
  void SetCancel(bool bCancel);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void PasswordNeeded(CryptoKeyStoragePasswordNeededEventParams *e);

// Or, subclass CryptoKeyStorage and override this emitter function.
virtual int FirePasswordNeeded(CryptoKeyStoragePasswordNeededEventParams *e) {...}

Remarks

The class fires this event when a password is needed to decrypt a certificate or a private key.

In the handler of this event, assign the password to the Password parameter, or set Cancel to true to abort the operation.

The NeededFor parameter identifies the key or certificate for which the password is requested.

CryptoKey Type

SecureBlackboxList Type

Syntax

SecureBlackboxList<T> (declared in secureblackbox.h)

Remarks

SecureBlackboxList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the CryptoKeyStorage class.

int GetCount() {}

int SetCount(int count) {}

T* Get(int index) {}

T* Set(int index, T* value) {}

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

Remarks

The CryptoKeyStorage class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the CryptoKeyStorage class an instance of that concrete class.

When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

bool CanRead() { return true; }

bool CanSeek() { return true; }

bool CanWrite() { return true; }

int64 GetLength() = 0;

void Close() {}

int Flush() { return 0; }

int Read(void* buffer, int count) = 0;

int64 Seek(int64 offset, int seekOrigin) = 0;

int Write(const void* buffer, int count) = 0;
