Config Method (PGPReader Class)

This method sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* secureblackbox_pgpreader_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.

DecryptAndVerify Method (PGPReader Class)

Decrypts and verifies a protected message.

Syntax

ANSI (Cross Platform)
int DecryptAndVerify();

Unicode (Windows)
INT DecryptAndVerify();
int secureblackbox_pgpreader_decryptandverify(void* lpObj);
int DecryptAndVerify();

Remarks

Use this method to unprotect a PGP message contained in a byte array (InputBytes), in a file (InputFile) or in a stream (InputStream). The method writes the decrypted message to a byte array (OutputBytes), to a file (OutputFile) or to a stream (OutputStream).

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.)

DoAction Method (PGPReader Class)

Performs an additional action.

Syntax

ANSI (Cross Platform)
char* DoAction(const char* lpszActionID, const char* lpszActionParams);

Unicode (Windows)
LPWSTR DoAction(LPCWSTR lpszActionID, LPCWSTR lpszActionParams);
char* secureblackbox_pgpreader_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;....

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.

Reset Method (PGPReader Class)

Resets the class settings.

Syntax

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();
int secureblackbox_pgpreader_reset(void* lpObj);
int Reset();

Remarks

Reset is a generic method available in every class.

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.)

VerifyDetached Method (PGPReader Class)

Verifies a detached signature.

Syntax

ANSI (Cross Platform)
int VerifyDetached();

Unicode (Windows)
INT VerifyDetached();
int secureblackbox_pgpreader_verifydetached(void* lpObj);
int VerifyDetached();

Remarks

};
// To handle, connect one or more slots to this signal. void EncryptionInfo(PGPReaderEncryptionInfoEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireEncryptionInfo(PGPReaderEncryptionInfoEventParams *e) {...}

Remarks

The class fires this event to report early encryption information. Use this event to find out what encryption type is used, and to provide appropriate decryption material (the secret keys or the password) via DecryptingKeys or Passphrase properties.

KeyIDs contains the IDs of the keys that can be used to decrypt the data. PassphraseUsed shows if the message can also be decrypted with a passphrase. Both can be set at the same time, indicating that each of the decryption routes can be taken.

EncryptedProtection parameter specifies whether the message includes a modification detection record.

Error Event (PGPReader Class)

Information about errors during PGP decryption/verification.

Syntax

ANSI (Cross Platform)
virtual int FireError(PGPReaderErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } PGPReaderErrorEventParams;
Unicode (Windows) virtual INT FireError(PGPReaderErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } PGPReaderErrorEventParams;
#define EID_PGPREADER_ERROR 2

virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class PGPReaderErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Error(PGPReaderErrorEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireError(PGPReaderErrorEventParams *e) {...}

Remarks

The event is fired in case of exceptional conditions during decryption/verification of protected data.

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

ExternalDecrypt Event (PGPReader Class)

Handles remote or external decryption.

Syntax

ANSI (Cross Platform)
virtual int FireExternalDecrypt(PGPReaderExternalDecryptEventParams *e);
typedef struct {
const char *OperationId;
const char *Algorithm;
const char *Pars;
const char *EncryptedData;
char *Data; int reserved; } PGPReaderExternalDecryptEventParams;
Unicode (Windows) virtual INT FireExternalDecrypt(PGPReaderExternalDecryptEventParams *e);
typedef struct {
LPCWSTR OperationId;
LPCWSTR Algorithm;
LPCWSTR Pars;
LPCWSTR EncryptedData;
LPWSTR Data; INT reserved; } PGPReaderExternalDecryptEventParams;
#define EID_PGPREADER_EXTERNALDECRYPT 3

virtual INT SECUREBLACKBOX_CALL FireExternalDecrypt(LPSTR &lpszOperationId, LPSTR &lpszAlgorithm, LPSTR &lpszPars, LPSTR &lpszEncryptedData, LPSTR &lpszData);
class PGPReaderExternalDecryptEventParams {
public:
  const QString &OperationId();

  const QString &Algorithm();

  const QString &Pars();

  const QString &EncryptedData();

  const QString &Data();
  void SetData(const QString &qsData);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void ExternalDecrypt(PGPReaderExternalDecryptEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireExternalDecrypt(PGPReaderExternalDecryptEventParams *e) {...}

Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.

Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

FileExtractionFinish Event (PGPReader Class)

Reports the ending of file extraction process.

Syntax

ANSI (Cross Platform)
virtual int FireFileExtractionFinish(PGPReaderFileExtractionFinishEventParams *e);
typedef struct {
const char *FileName;
const char *Timestamp; int reserved; } PGPReaderFileExtractionFinishEventParams;
Unicode (Windows) virtual INT FireFileExtractionFinish(PGPReaderFileExtractionFinishEventParams *e);
typedef struct {
LPCWSTR FileName;
LPCWSTR Timestamp; INT reserved; } PGPReaderFileExtractionFinishEventParams;
#define EID_PGPREADER_FILEEXTRACTIONFINISH 4

virtual INT SECUREBLACKBOX_CALL FireFileExtractionFinish(LPSTR &lpszFileName, LPSTR &lpszTimestamp);
class PGPReaderFileExtractionFinishEventParams {
public:
  const QString &FileName();

  const QString &Timestamp();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void FileExtractionFinish(PGPReaderFileExtractionFinishEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireFileExtractionFinish(PGPReaderFileExtractionFinishEventParams *e) {...}

Remarks

This event informs about the ending of extraction of the next available file. FileName parameter indicates the original file name, and the Timestamp its last modification time.

In the handler, the user can take away the output stream or store the file data from OutputBytes.

FileExtractionStart Event (PGPReader Class)

Reports the beginning of file extraction process.

Syntax

ANSI (Cross Platform)
virtual int FireFileExtractionStart(PGPReaderFileExtractionStartEventParams *e);
typedef struct {
const char *FileName;
const char *Timestamp;
int Skip; int reserved; } PGPReaderFileExtractionStartEventParams;
Unicode (Windows) virtual INT FireFileExtractionStart(PGPReaderFileExtractionStartEventParams *e);
typedef struct {
LPCWSTR FileName;
LPCWSTR Timestamp;
BOOL Skip; INT reserved; } PGPReaderFileExtractionStartEventParams;
#define EID_PGPREADER_FILEEXTRACTIONSTART 5

virtual INT SECUREBLACKBOX_CALL FireFileExtractionStart(LPSTR &lpszFileName, LPSTR &lpszTimestamp, BOOL &bSkip);
class PGPReaderFileExtractionStartEventParams {
public:
  const QString &FileName();

  const QString &Timestamp();

  bool Skip();
  void SetSkip(bool bSkip);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void FileExtractionStart(PGPReaderFileExtractionStartEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireFileExtractionStart(PGPReaderFileExtractionStartEventParams *e) {...}

Remarks

This event informs about the beginning of extraction of the next available file. A PGP message may contain more than one file. FileName parameter indicates the original file name, and the Timestamp its last modification time.

The user should provide an output filename in OutputFile or a stream in OutputStream. If none of them is provided, the extracted file will be placed to OutputBytes. After the file is extracted, FileExtractionFinish event is fired.

KeyPassphraseNeeded Event (PGPReader Class)

Requests a key protection password from the application.

Syntax

ANSI (Cross Platform)
virtual int FireKeyPassphraseNeeded(PGPReaderKeyPassphraseNeededEventParams *e);
typedef struct {
const char *KeyID;
const char *UserID;
int MainKey;
char *Passphrase;
int Skip; int reserved; } PGPReaderKeyPassphraseNeededEventParams;
Unicode (Windows) virtual INT FireKeyPassphraseNeeded(PGPReaderKeyPassphraseNeededEventParams *e);
typedef struct {
LPCWSTR KeyID;
LPCWSTR UserID;
BOOL MainKey;
LPWSTR Passphrase;
BOOL Skip; INT reserved; } PGPReaderKeyPassphraseNeededEventParams;
#define EID_PGPREADER_KEYPASSPHRASENEEDED 6

virtual INT SECUREBLACKBOX_CALL FireKeyPassphraseNeeded(LPSTR &lpszKeyID, LPSTR &lpszUserID, BOOL &bMainKey, LPSTR &lpszPassphrase, BOOL &bSkip);
class PGPReaderKeyPassphraseNeededEventParams {
public:
  const QString &KeyID();

  const QString &UserID();

  bool MainKey();

  const QString &Passphrase();
  void SetPassphrase(const QString &qsPassphrase);

  bool Skip();
  void SetSkip(bool bSkip);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void KeyPassphraseNeeded(PGPReaderKeyPassphraseNeededEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireKeyPassphraseNeeded(PGPReaderKeyPassphraseNeededEventParams *e) {...}

Remarks

The class fires this event to request a secret key passphrase from the application. Note that this event asks for a key protection passphrase rather than a message protection passphrase (which is requested via PassphraseNeeded). The class fires it when it has found a suitable decryption secret key in the keyring, and attempts to use it to decrypt the data.

If the data is encrypted with multiple keys, this event is called for each key in a loop until the password for at least one key is provided correctly. KeyID specifies the key for which the password is requested, and UserID identifies its user. MainKey tells whether the key is a master key or a subkey.

The handler should provide password via the Passphrase parameter, or set Skip to True to skip this key.

For each key KeyPassphraseNeeded is called in a loop until the correct password is provided or the maximum number of password attempts reached.

MultipleFilesFound Event (PGPReader Class)

Fires if the PGP message is recognized to contain multiple files.

Syntax

ANSI (Cross Platform)
virtual int FireMultipleFilesFound(PGPReaderMultipleFilesFoundEventParams *e);
typedef struct {
const char *TarFileName;
int Proceed; int reserved; } PGPReaderMultipleFilesFoundEventParams;
Unicode (Windows) virtual INT FireMultipleFilesFound(PGPReaderMultipleFilesFoundEventParams *e);
typedef struct {
LPCWSTR TarFileName;
BOOL Proceed; INT reserved; } PGPReaderMultipleFilesFoundEventParams;
#define EID_PGPREADER_MULTIPLEFILESFOUND 7

virtual INT SECUREBLACKBOX_CALL FireMultipleFilesFound(LPSTR &lpszTarFileName, BOOL &bProceed);
class PGPReaderMultipleFilesFoundEventParams {
public:
  const QString &TarFileName();

  bool Proceed();
  void SetProceed(bool bProceed);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void MultipleFilesFound(PGPReaderMultipleFilesFoundEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireMultipleFilesFound(PGPReaderMultipleFilesFoundEventParams *e) {...}

Remarks

The class fires this event to report that there is more than one file in the PGP message.

The TarFileName specifies the name of the TAR file containing the files. Tune up Proceed to go ahead or stop the processing.

Notification Event (PGPReader Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireNotification(PGPReaderNotificationEventParams *e);
typedef struct {
const char *EventID;
const char *EventParam; int reserved; } PGPReaderNotificationEventParams;
Unicode (Windows) virtual INT FireNotification(PGPReaderNotificationEventParams *e);
typedef struct {
LPCWSTR EventID;
LPCWSTR EventParam; INT reserved; } PGPReaderNotificationEventParams;
#define EID_PGPREADER_NOTIFICATION 8

virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);
class PGPReaderNotificationEventParams {
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(PGPReaderNotificationEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireNotification(PGPReaderNotificationEventParams *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.

PassphraseNeeded Event (PGPReader Class)

Requests a data protection password from the application.

Syntax

ANSI (Cross Platform)
virtual int FirePassphraseNeeded(PGPReaderPassphraseNeededEventParams *e);
typedef struct {
char *Passphrase;
int Skip; int reserved; } PGPReaderPassphraseNeededEventParams;
Unicode (Windows) virtual INT FirePassphraseNeeded(PGPReaderPassphraseNeededEventParams *e);
typedef struct {
LPWSTR Passphrase;
BOOL Skip; INT reserved; } PGPReaderPassphraseNeededEventParams;
#define EID_PGPREADER_PASSPHRASENEEDED 9

virtual INT SECUREBLACKBOX_CALL FirePassphraseNeeded(LPSTR &lpszPassphrase, BOOL &bSkip);
class PGPReaderPassphraseNeededEventParams {
public:
  const QString &Passphrase();
  void SetPassphrase(const QString &qsPassphrase);

  bool Skip();
  void SetSkip(bool bSkip);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void PassphraseNeeded(PGPReaderPassphraseNeededEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FirePassphraseNeeded(PGPReaderPassphraseNeededEventParams *e) {...}

Remarks

The class fires this event to request a decryption password. It is only fired if the data can be decrypted without a key.

The event is fired in a loop until the correct password is passed or the number of password attempts is exceeded.

Progress Event (PGPReader Class)

Reports the progress of the decryption operation.

Syntax

ANSI (Cross Platform)
virtual int FireProgress(PGPReaderProgressEventParams *e);
typedef struct {
int64 Current;
int64 Total;
int Cancel; int reserved; } PGPReaderProgressEventParams;
Unicode (Windows) virtual INT FireProgress(PGPReaderProgressEventParams *e);
typedef struct {
LONG64 Current;
LONG64 Total;
BOOL Cancel; INT reserved; } PGPReaderProgressEventParams;
#define EID_PGPREADER_PROGRESS 10

virtual INT SECUREBLACKBOX_CALL FireProgress(LONG64 &lCurrent, LONG64 &lTotal, BOOL &bCancel);
class PGPReaderProgressEventParams {
public:
  qint64 Current();

  qint64 Total();

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

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Progress(PGPReaderProgressEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireProgress(PGPReaderProgressEventParams *e) {...}

Remarks

The class fires this event repeatedly to report the progress of the file extraction operation.

Current indicates the amount of processed data in bytes, and Total is the total number of bytes to be processed. Use Cancel to terminate the extraction process.

Signed Event (PGPReader Class)

Notifies the application about a signed message.

Syntax

ANSI (Cross Platform)
virtual int FireSigned(PGPReaderSignedEventParams *e);
typedef struct {
const char *KeyIDs;
int SignatureType; int reserved; } PGPReaderSignedEventParams;
Unicode (Windows) virtual INT FireSigned(PGPReaderSignedEventParams *e);
typedef struct {
LPCWSTR KeyIDs;
INT SignatureType; INT reserved; } PGPReaderSignedEventParams;
#define EID_PGPREADER_SIGNED 11

virtual INT SECUREBLACKBOX_CALL FireSigned(LPSTR &lpszKeyIDs, INT &iSignatureType);
class PGPReaderSignedEventParams {
public:
  const QString &KeyIDs();

  int SignatureType();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Signed(PGPReaderSignedEventParams *e);
// Or, subclass PGPReader and override this emitter function. virtual int FireSigned(PGPReaderSignedEventParams *e) {...}

Remarks

The class fires this event when it identifies a signed message to allow the application to prepare the component for verification.

Use the KeyIDs parameter to identify keys used that were used to sign the message, and make sure they are available in the VerifyingKeys list.

SignatureType indicates the signature type:

pstNormal0A traditional signature, compatible (algorithm permitting) with PGP 2.6.x

pstOnePass1A newer one-pass signature

pstDetached2A detached signature, i.e., a signature contained in a separate file from the data it covers

pstCleartext3A signature made over textual data and appended to it

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Syntax

SecureBlackboxExternalCrypto (declared in secureblackbox.h)

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

AsyncDocumentID
char*

Default Value: ""

Specifies an optional document ID for SignAsyncBegin() and SignAsyncEnd() calls.

Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. On the completion stage, this value helps the signing component identify the correct signature in the returned batch of responses.

If using batched requests, make sure to set this property to the same value on both the pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

CustomParams
char*

Default Value: ""

Custom parameters to be passed to the signing service (uninterpreted).

Data
char*

Default Value: ""

Additional data to be included in the async state and mirrored back by the requestor.

ExternalHashCalculation
int

Default Value: FALSE

Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth class.

If set to true, the class will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.

HashAlgorithm
char*

Default Value: "SHA256"

Specifies the request's signature hash algorithm.

SB_HASH_ALGORITHM_SHAKE_128_LENSHAKE_128_LEN
SB_HASH_ALGORITHM_SHAKE_256_LENSHAKE_256_LEN

KeyID
char*

Default Value: ""

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

KeySecret
char*

Default Value: ""

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Read more about configuring authentication in the topic.

Method
int

Default Value: 0

Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.

Available options:

asmdPKCS10
asmdPKCS71

Mode
int

Default Value: 0

Specifies the external cryptography mode.

Available options:

ecmDefaultThe default value (0)
ecmDisabledDo not use DC or external signing (1)
ecmGenericGeneric external signing with the OnExternalSign event (2)
ecmDCAuthDCAuth signing (3)
ecmDCAuthJSONDCAuth signing in JSON format (4)

PublicKeyAlgorithm
char*

Default Value: ""

Provide the public key algorithm here if the certificate is not available on the pre-signing stage.

ExternalCrypto()

Creates a new ExternalCrypto object with default field values.

PGPKey Type

This container represents a PGP key.

Syntax

SecureBlackboxPGPKey (declared in secureblackbox.h)

Remarks

OpenPGP standard supports several types of keys. In our days, a typical OpenPGP keypair actually consists of two cryptographic keys: a primary key and a subkey. The primary key is normally used for signing, while the subkey is used for encryption.

While it is typical for PGP environments to use a primary key/subkey bundle, this is not a must. Sometimes you may come across standalone keys (mainly when dealing with older implementations), as well as whole key trees, each of those carrying a bunch of differently-purposed subkeys bound to the same primary key.

Algorithm-wise, OpenPGP keys also differ. Generally speaking, OpenPGP supports the following public key algorithms: RSA, Elgamal (often incorrectly referred to as DH), DSA, ECDH and ECDSA. When it comes to primary key/subkey bundles, DSA/Elgamal, RSA/RSA and ECDSA/ECDH pairs are typically used. Although there's no restriction on algorithm bundles, and, e.g. a ECDSA/Elgamal key bundle is perfectly possible, such combination is rarely used in practice.

A typical OpenPGP key is associated with some kind of user ID (Username). It is normally represented with a user's e-mail address, while in theory can be any piece of text. The secret part of the OpenPGP keypair is protected with a password (Passphrase).

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 PGPReader class.

Methods

GetCount This method returns the current size of the collection.

int GetCount() {}

SetCount This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection.

int SetCount() {}

Get This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified.

T* Get(int index) {}

Set This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class.

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

Config Settings (PGPReader Class)

The class accepts one or more of the following configuration settings. Configuration 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.

PGPReader Config Settings

IgnoreDataPacketLengths:   Whether to check the length of input data packets.

Set this property to True to prevent the class from checking input packet lengths.

PasswordAttempts:   The number of attempts allowed for entering password.

Use this property to specify how many times a wrong password may be entered.

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

UndefInputLength:   Set this property if you are working with non-seekable streams.

Use this property to turn on support for streams with unknown length and position parameters, such as network or database streams. It prevents the class from checking input stream length or position.

UseGreedyMemoryConsumption:   Whether to limit memory consumption for the cost of speed.

When this property is True, the class uses more memory, but decrypts data faster. Otherwise, less memory is consumed, but the decryption is slower.

Base Config Settings

CheckKeyIntegrityBeforeUse:   Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching:   Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the class.

Supported values are:

Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions.

DefDeriveKeyIterations:   Specifies the default key derivation algorithm iteration count.

This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

EnableClientSideSSLFFDHE:   Enables or disables finite field DHE key exchange support in TLS clients.

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies:   Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global".

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

LogMaxEventCount:   Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

MaxASN1BufferLength:   Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth:   Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm:   Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the class. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

StaticIPAddress[domain]:   Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the class) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses:   Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

TLSSessionGroup:   Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

TLSSessionLifetime:   Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval:   Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

UseOwnDNSResolver:   Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages:   Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemOAEPAndPSS:   Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom:   Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

Trappable Errors (PGPReader Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.
