SecureBlackboxList* GetBlockedCertificates(); int SetBlockedCertificates(SecureBlackboxList* val); ``` ## Remarks Use this property to provide a list of compromised or blocked certificates. Any chain containing a blocked certificate will fail validation. This property is not available at design time. ## Data Type [SecureBlackboxCertificate](#certificate-type) # Connected Property ([TLSClient](#tlsclient-class) Class) Indicates whether the connection is active. ## Syntax ```text ANSI (Cross Platform) int GetConnected(); Unicode (Windows) BOOL GetConnected(); ``` ## Default Value FALSE ## Remarks Use this property to check if the connection is alive. This property is read-only and not available at design time. ## Data Type Boolean # ConnectionInfo Property ([TLSClient](#tlsclient-class) Class) Returns the details of the underlying network connection. ## Syntax ```text SecureBlackboxTLSConnectionInfo* GetConnectionInfo(); ``` ## Remarks Use this property to learn about the connection setup, such as the protocol security details and amounts of data transferred each way. This property is read-only and not available at design time. ## Data Type [SecureBlackboxTLSConnectionInfo](#tlsconnectioninfo-type) # ExternalCrypto Property ([TLSClient](#tlsclient-class) Class) Provides access to external signing and DC parameters. ## Syntax ```text SecureBlackboxExternalCrypto* GetExternalCrypto(); ``` ## Remarks Use this property to tune-up remote cryptography settings. SecureBlackbox supports two independent types of external cryptography: synchronous (based on the [ExternalSign](#externalsign-event-tlsclient-class) event) and asynchronous (based on the DC protocol and the DCAuth signing component). This property is read-only. ## Data Type [SecureBlackboxExternalCrypto](#externalcrypto-type) # FIPSMode Property ([TLSClient](#tlsclient-class) Class) Reserved. ## Syntax ```text ANSI (Cross Platform) int GetFIPSMode();int SetFIPSMode(int bFIPSMode); Unicode (Windows) BOOL GetFIPSMode();INT SetFIPSMode(BOOL bFIPSMode); ``` ## Default Value FALSE ## Remarks This property is reserved for future use. ## Data Type Boolean # KnownCertificates Property ([TLSClient](#tlsclient-class) Class) Additional certificates for chain validation. ## Syntax ```text SecureBlackboxList* GetKnownCertificates(); int SetKnownCertificates(SecureBlackboxList* val); ``` ## Remarks Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the class manually. The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows. Do not add trust anchors or root certificates to this collection: add them to [TrustedCertificates](#trustedcertificates-property-tlsclient-class) instead. This property is not available at design time. ## Data Type [SecureBlackboxCertificate](#certificate-type) # KnownCRLs Property ([TLSClient](#tlsclient-class) Class) Additional CRLs for chain validation. ## Syntax ```text SecureBlackboxList* GetKnownCRLs(); int SetKnownCRLs(SecureBlackboxList* val); ``` ## Remarks Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document. This property is not available at design time. ## Data Type [SecureBlackboxCRL](#crl-type) # KnownOCSPs Property ([TLSClient](#tlsclient-class) Class) Additional OCSP responses for chain validation. ## Syntax ```text SecureBlackboxList* GetKnownOCSPs(); int SetKnownOCSPs(SecureBlackboxList* val); ``` ## Remarks Use this property to supply additional OCSP responses that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated OCSP responses are stored separately from the signed message or document. This property is not available at design time. ## Data Type [SecureBlackboxOCSPResponse](#ocspresponse-type) # OutputBytes Property ([TLSClient](#tlsclient-class) Class) A memory buffer where the incoming data is collected. ## Syntax ```text ANSI (Cross Platform) int GetOutputBytes(char* &lpOutputBytes, int &lenOutputBytes); Unicode (Windows) INT GetOutputBytes(LPSTR &lpOutputBytes, INT &lenOutputBytes); ``` ## Remarks Use this property to access the cached incoming data after a [ReceiveData](#receivedata-method-tlsclient-class) or [ReceiveAllData](#receivealldata-method-tlsclient-class) call. This property is read-only and not available at design time. ## Data Type Byte Array # OutputString Property ([TLSClient](#tlsclient-class) Class) A string where the incoming data is collected. ## Syntax ```text ANSI (Cross Platform) char* GetOutputString(); Unicode (Windows) LPWSTR GetOutputString(); ``` ## Default Value "" ## Remarks Use this property to access the stored incoming data in the string interpretation. This property is read-only and not available at design time. ## Data Type String # Proxy Property ([TLSClient](#tlsclient-class) Class) The proxy server settings. ## Syntax ```text SecureBlackboxProxySettings* GetProxy(); ``` ## Remarks Use this property to tune up the proxy server settings. This property is read-only. ## Data Type [SecureBlackboxProxySettings](#proxysettings-type) # SocketSettings Property ([TLSClient](#tlsclient-class) Class) Manages network connection settings. ## Syntax ```text SecureBlackboxSocketSettings* GetSocketSettings(); ``` ## Remarks Use this property to tune up network connection parameters. This property is read-only. ## Data Type [SecureBlackboxSocketSettings](#socketsettings-type) # TLSClientChain Property ([TLSClient](#tlsclient-class) Class) The TLS client certificate chain. ## Syntax ```text SecureBlackboxList* GetTLSClientChain(); int SetTLSClientChain(SecureBlackboxList* val); ``` ## Remarks Assign a certificate chain to this property to enable TLS client authentication in the class. Note that the client's end-entity certificate should have a private key associated with it. Use the [CertificateStorage](CertificateStorage.md#CertificateStorage) or [CertificateManager](CertificateManager.md#CertificateManager) components to import the certificate from a file, system store, or PKCS11 device. This property is not available at design time. ## Data Type [SecureBlackboxCertificate](#certificate-type) # TLSServerChain Property ([TLSClient](#tlsclient-class) Class) The TLS server's certificate chain. ## Syntax ```text SecureBlackboxList* GetTLSServerChain(); ``` ## Remarks Use this property to access the certificate chain sent by the TLS server. This property is ready to read when the [TLSCertValidate](#tlscertvalidate-event-tlsclient-class) event is fired by the client component. This property is read-only and not available at design time. ## Data Type [SecureBlackboxCertificate](#certificate-type) # TLSSettings Property ([TLSClient](#tlsclient-class) Class) Manages TLS layer settings. ## Syntax ```text SecureBlackboxTLSSettings* GetTLSSettings(); ``` ## Remarks Use this property to tune up the TLS layer parameters. This property is read-only. ## Data Type [SecureBlackboxTLSSettings](#tlssettings-type) # TrustedCertificates Property ([TLSClient](#tlsclient-class) Class) A list of trusted certificates for chain validation. ## Syntax ```text SecureBlackboxList* GetTrustedCertificates(); int SetTrustedCertificates(SecureBlackboxList* val); ``` ## Remarks Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually. The purpose of this certificate collection is largely the same as that of the Windows Trusted Root Certification Authorities system store. Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust. This property is not available at design time. ## Data Type [SecureBlackboxCertificate](#certificate-type) # Config Method ([TLSClient](#tlsclient-class) Class) Sets or retrieves a configuration setting. ## Syntax ```text ANSI (Cross Platform) char* Config(const char* lpszConfigurationString); Unicode (Windows) LPWSTR Config(LPCWSTR lpszConfigurationString); ``` ## Remarks Config is a generic method available in every class. It is used to set and retrieve [configuration settings](#config-settings-tlsclient-class) 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](#config-settings-tlsclient-class), 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. # Connect Method ([TLSClient](#tlsclient-class) Class) Establishes connection to a remote server. ## Syntax ```text ANSI (Cross Platform) int Connect(const char* lpszAddress, int iPort); Unicode (Windows) INT Connect(LPCWSTR lpszAddress, INT iPort); ``` ## Remarks Call this method to establish connection to a TLS server at *Address*:*Port*. ## 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.) # Disconnect Method ([TLSClient](#tlsclient-class) Class) Disconnects from the server. ## Syntax ```text ANSI (Cross Platform) int Disconnect(); Unicode (Windows) INT Disconnect(); ``` ## Remarks Call this method to close an active connection to the server. ## 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 ([TLSClient](#tlsclient-class) Class) Performs an additional action. ## Syntax ```text ANSI (Cross Platform) char* DoAction(const char* lpszActionID, const char* lpszActionParams); Unicode (Windows) LPWSTR DoAction(LPCWSTR lpszActionID, LPCWSTR lpszActionParams); ``` ## 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: | | | | | | --- | --- | --- | --- | | Action | Parameters | Returned value | Description | | ResetTrustedListCache | none | none | Clears the cached list of trusted lists. | | ResetCertificateCache | none | none | Clears the cached certificates. | | ResetCRLCache | none | none | Clears the cached CRLs. | | ResetOCSPResponseCache | none | none | Clears the cached OCSP responses. | ## 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. # ExportKeyMaterial Method ([TLSClient](#tlsclient-class) Class) Derives key material from the session's master key using the TLS exporters scheme. ## Syntax ```text ANSI (Cross Platform) int ExportKeyMaterial(const char* lpszLbl, const char* lpContext, int lenContext, int iLen); Unicode (Windows) INT ExportKeyMaterial(LPCWSTR lpszLbl, LPCSTR lpContext, INT lenContext, INT iLen); ``` ## Remarks Some protocols - for example, SRTP - use TLS exporters to derive their own session keys from the TLS master key. This method lets you employ the exporters scheme to obtain such keys, or to generate secure keys for your own needs from the current TLS session. The exported keys depend on the master key, and are different for every TLS session. However, a client and server sharing a session will always end up with the same key material, as long as they use the same values of *Lbl*, *Context*, and *Len*. ## 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.) # ReceiveAllData Method ([TLSClient](#tlsclient-class) Class) Reads data from the connection. ## Syntax ```text ANSI (Cross Platform) int ReceiveAllData(int iSize); Unicode (Windows) INT ReceiveAllData(INT iSize); ``` ## Remarks Use this method to read *Size* bytes from the connection. The method will block until the requested number of bytes is received. Use [OutputBytes](#outputbytes-property-tlsclient-class) (or [OutputString](#outputstring-property-tlsclient-class)) to access the received data. Use [ReceiveData](#receivedata-method-tlsclient-class) method to read all the data there is and return without waiting for the whole piece. ## 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.) # ReceiveData Method ([TLSClient](#tlsclient-class) Class) Reads data from the connection. ## Syntax ```text ANSI (Cross Platform) int ReceiveData(int iSize); Unicode (Windows) INT ReceiveData(INT iSize); ``` ## Remarks Use this method to read *Size* or less bytes from the connection. The method will read as much data is possible (but no more than *Size*) and return without blocking. Use [OutputBytes](#outputbytes-property-tlsclient-class) (or [OutputString](#outputstring-property-tlsclient-class)) to access the received data. ## 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.) # Reset Method ([TLSClient](#tlsclient-class) Class) Resets the class settings. ## Syntax ```text ANSI (Cross Platform) int Reset(); Unicode (Windows) 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.) # SendKeepAlive Method ([TLSClient](#tlsclient-class) Class) Sends a keep-alive packet. ## Syntax ```text ANSI (Cross Platform) int SendKeepAlive(); Unicode (Windows) INT SendKeepAlive(); ``` ## Remarks Use this method to send a keep-alive packet to the server. Keep alive is an empty packet; keep-alive signals sent occasionally can be used to keep connection up. ## 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.) # SendStream Method ([TLSClient](#tlsclient-class) Class) Sends data contained in a stream to the server. ## Syntax ```text ANSI (Cross Platform) int SendStream(SecureBlackboxStream* sStream); Unicode (Windows) INT SendStream(SecureBlackboxStream* sStream); ``` ## Remarks Use this method to send the content of a stream to the server. ## 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.

Use the *Quiet* parameter to suppress sending of the close_notify alert upon closing the TLS session. ## 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.) # Error Event ([TLSClient](#tlsclient-class) Class) Information about errors during data delivery. ## Syntax ```text ANSI (Cross Platform) virtual int FireError(TLSClientErrorEventParams *e); typedef struct { int ErrorCode; int Fatal; int Remote; const char *Description; int reserved; } TLSClientErrorEventParams; Unicode (Windows) virtual INT FireError(TLSClientErrorEventParams *e); typedef struct { INT ErrorCode; BOOL Fatal; BOOL Remote; LPCWSTR Description; INT reserved; } TLSClientErrorEventParams; ``` ## Remarks The event is fired in case of exceptional conditions during message processing. *ErrorCode* contains an error code and *Description* contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [HTTPS](#trappable-errors-tlsclient-class) section. # ExternalSign Event ([TLSClient](#tlsclient-class) Class) Handles remote or external signing initiated by the SignExternal method or other source. ## Syntax ```text ANSI (Cross Platform) virtual int FireExternalSign(TLSClientExternalSignEventParams *e); typedef struct { const char *OperationId; const char *HashAlgorithm; const char *Pars; const char *Data; char *SignedData; int reserved; } TLSClientExternalSignEventParams; Unicode (Windows) virtual INT FireExternalSign(TLSClientExternalSignEventParams *e); typedef struct { LPCWSTR OperationId; LPCWSTR HashAlgorithm; LPCWSTR Pars; LPCWSTR Data; LPWSTR SignedData; INT reserved; } TLSClientExternalSignEventParams; ``` ## Remarks Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed. The event handler must pass the value of *Data* to the signer, obtain the signature, and pass it back to the class via the *SignedData* parameter. *OperationId* provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. *HashAlgorithm* specifies the hash algorithm being used for the operation, and *Pars* contains algorithm-dependent parameters. The class uses base16 (hex) encoding for the *Data*, *SignedData*, and *Pars* parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing. A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16 A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: ```text signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); }; ``` # Notification Event ([TLSClient](#tlsclient-class) Class) This event notifies the application about an underlying control flow event. ## Syntax ```text ANSI (Cross Platform) virtual int FireNotification(TLSClientNotificationEventParams *e); typedef struct { const char *EventID; const char *EventParam; int reserved; } TLSClientNotificationEventParams; Unicode (Windows) virtual INT FireNotification(TLSClientNotificationEventParams *e); typedef struct { LPCWSTR EventID; LPCWSTR EventParam; INT reserved; } TLSClientNotificationEventParams; ``` ## 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. This class can fire this event with the following *EventID* values: | | | | --- | --- | | TLSExtensions.CertificateStatus | TBD | | TLSExtensions.PreSharedIdentityHint | TBD | # TLSCertNeeded Event ([TLSClient](#tlsclient-class) Class) Fires when a remote TLS party requests a client certificate. ## Syntax ```text ANSI (Cross Platform) virtual int FireTLSCertNeeded(TLSClientTLSCertNeededEventParams *e); typedef struct { const char *Host; const char *CANames; int reserved; } TLSClientTLSCertNeededEventParams; Unicode (Windows) virtual INT FireTLSCertNeeded(TLSClientTLSCertNeededEventParams *e); typedef struct { LPCWSTR Host; LPCWSTR CANames; INT reserved; } TLSClientTLSCertNeededEventParams; ``` ## Remarks This event fires to notify the implementation that a remote TLS server has requested a client certificate. The *Host* parameter identifies the host that makes a request, and the *CANames* parameter (optional, according to the TLS spec) advises on the accepted issuing CAs. Use the [TLSClientChain](#tlsclientchain-property-tlsclient-class) property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire. This event is preceded by the [TLSHandshake](#tlshandshake-event-tlsclient-class) event for the given host and, if the certificate was accepted, succeeded by the [TLSEstablished](#tlsestablished-event-tlsclient-class) event. # TLSCertValidate Event ([TLSClient](#tlsclient-class) Class) This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance. ## Syntax ```text ANSI (Cross Platform) virtual int FireTLSCertValidate(TLSClientTLSCertValidateEventParams *e); typedef struct { const char *ServerHost; const char *ServerIP; int Accept; int reserved; } TLSClientTLSCertValidateEventParams; Unicode (Windows) virtual INT FireTLSCertValidate(TLSClientTLSCertValidateEventParams *e); typedef struct { LPCWSTR ServerHost; LPCWSTR ServerIP; BOOL Accept; INT reserved; } TLSClientTLSCertValidateEventParams; ``` ## Remarks This event is fired during a TLS handshake. Use the [TLSServerChain](#tlsserverchain-property-tlsclient-class) property to access the certificate chain. In general, classes may contact a number of TLS endpoints during their work, depending on their configuration. *Accept* is assigned in accordance with the outcome of the internal validation check performed by the class, and can be adjusted if needed. # TLSEstablished Event ([TLSClient](#tlsclient-class) Class) Fires when a TLS handshake with Host successfully completes. ## Syntax ```text ANSI (Cross Platform) virtual int FireTLSEstablished(TLSClientTLSEstablishedEventParams *e); typedef struct { const char *Host; const char *Version; const char *Ciphersuite; const char *ConnectionId; int lenConnectionId; int Abort; int reserved; } TLSClientTLSEstablishedEventParams; Unicode (Windows) virtual INT FireTLSEstablished(TLSClientTLSEstablishedEventParams *e); typedef struct { LPCWSTR Host; LPCWSTR Version; LPCWSTR Ciphersuite; LPCSTR ConnectionId; INT lenConnectionId; BOOL Abort; INT reserved; } TLSClientTLSEstablishedEventParams; ``` ## Remarks The class uses this event to notify the application about a successful completion of a TLS handshake. The *Version*, *Ciphersuite*, and *ConnectionId* parameters indicate the security parameters of the new connection. Use the *Abort* parameter if you need to terminate the connection at this stage. # TLSHandshake Event ([TLSClient](#tlsclient-class) Class) Fires when a new TLS handshake is initiated, before the handshake commences. ## Syntax ```text ANSI (Cross Platform) virtual int FireTLSHandshake(TLSClientTLSHandshakeEventParams *e); typedef struct { const char *Host; int Abort; int reserved; } TLSClientTLSHandshakeEventParams; Unicode (Windows) virtual INT FireTLSHandshake(TLSClientTLSHandshakeEventParams *e); typedef struct { LPCWSTR Host; BOOL Abort; INT reserved; } TLSClientTLSHandshakeEventParams; ``` ## Remarks The class uses this event to notify the application about the start of a new TLS handshake to *Host*. If the handshake is successful, this event will be followed by the [TLSEstablished](#tlsestablished-event-tlsclient-class) event. If the server chooses to request a client certificate, the [TLSCertNeeded](#tlscertneeded-event-tlsclient-class) event will also be fired. # TLSPSK Event ([TLSClient](#tlsclient-class) Class) Notifies the application about the PSK key exchange. ## Syntax ```text ANSI (Cross Platform) virtual int FireTLSPSK(TLSClientTLSPSKEventParams *e); typedef struct { const char *Host; const char *Hint; int reserved; } TLSClientTLSPSKEventParams; Unicode (Windows) virtual INT FireTLSPSK(TLSClientTLSPSKEventParams *e); typedef struct { LPCWSTR Host; LPCWSTR Hint; INT reserved; } TLSClientTLSPSKEventParams; ``` ## Remarks The class fires this event to notify the application about the beginning of TLS-PSK key exchange with *Host*. The *Hint* parameter may be used by the server to identify the key or service to use. Use the PreSharedKey field of [TLSSettings](#tlssettings-property-tlsclient-class) to provide the pre-shared key to the component. # TLSShutdown Event ([TLSClient](#tlsclient-class) Class) Reports the graceful closure of a TLS connection. ## Syntax ```text ANSI (Cross Platform) virtual int FireTLSShutdown(TLSClientTLSShutdownEventParams *e); typedef struct { const char *Host; int reserved; } TLSClientTLSShutdownEventParams; Unicode (Windows) virtual INT FireTLSShutdown(TLSClientTLSShutdownEventParams *e); typedef struct { LPCWSTR Host; INT reserved; } TLSClientTLSShutdownEventParams; ``` ## Remarks This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported. # Certificate Type Encapsulates an individual X.509 certificate. ## Syntax *SecureBlackboxCertificate* (declared in *secureblackbox.h*) ## Remarks This type keeps and provides access to X.509 certificate details. The following fields are available: - [Bytes](#Certificate_f_Bytes) - [CA](#Certificate_f_CA) - [CAKeyID](#Certificate_f_CAKeyID) - [CertType](#Certificate_f_CertType) - [CRLDistributionPoints](#Certificate_f_CRLDistributionPoints) - [Curve](#Certificate_f_Curve) - [Fingerprint](#Certificate_f_Fingerprint) - [FriendlyName](#Certificate_f_FriendlyName) - [Handle](#Certificate_f_Handle) - [HashAlgorithm](#Certificate_f_HashAlgorithm) - [Issuer](#Certificate_f_Issuer) - [IssuerRDN](#Certificate_f_IssuerRDN) - [KeyAlgorithm](#Certificate_f_KeyAlgorithm) - [KeyBits](#Certificate_f_KeyBits) - [KeyFingerprint](#Certificate_f_KeyFingerprint) - [KeyUsage](#Certificate_f_KeyUsage) - [KeyValid](#Certificate_f_KeyValid) - [OCSPLocations](#Certificate_f_OCSPLocations) - [OCSPNoCheck](#Certificate_f_OCSPNoCheck) - [Origin](#Certificate_f_Origin) - [PolicyIDs](#Certificate_f_PolicyIDs) - [PrivateKeyBytes](#Certificate_f_PrivateKeyBytes) - [PrivateKeyExists](#Certificate_f_PrivateKeyExists) - [PrivateKeyExtractable](#Certificate_f_PrivateKeyExtractable) - [PublicKeyBytes](#Certificate_f_PublicKeyBytes) - [Qualified](#Certificate_f_Qualified) - [QualifiedStatements](#Certificate_f_QualifiedStatements) - [Qualifiers](#Certificate_f_Qualifiers) - [SelfSigned](#Certificate_f_SelfSigned) - [SerialNumber](#Certificate_f_SerialNumber) - [SigAlgorithm](#Certificate_f_SigAlgorithm) - [Source](#Certificate_f_Source) - [Subject](#Certificate_f_Subject) - [SubjectAlternativeName](#Certificate_f_SubjectAlternativeName) - [SubjectKeyID](#Certificate_f_SubjectKeyID) - [SubjectRDN](#Certificate_f_SubjectRDN) - [Valid](#Certificate_f_Valid) - [ValidFrom](#Certificate_f_ValidFrom) - [ValidTo](#Certificate_f_ValidTo) ## Fields **Bytes** *char* (read-only)* *Default Value: * Returns the raw certificate data in DER format. **CA** *int* *Default Value: FALSE* Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled. Set this field when generating a new certificate to have its Basic Constraints extension generated automatically. **CAKeyID** *char* (read-only)* *Default Value: * A unique identifier (fingerprint) of the CA certificate's cryptographic key. Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building. This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](CertificateManager.md#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [SubjectKeyID](#Certificate_f_SubjectKeyID) setting, and for lower-level certificates, from the parent certificate's subject key ID extension. **CertType** *int (read-only)* *Default Value: 0* Returns the type of the entity contained in the [Certificate](#certificate-type) object. A [Certificate](#certificate-type) object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate. Use the [CertificateManager](CertificateManager.md#CertificateManager) class to load or create new certificate and certificate requests objects. **CRLDistributionPoints** *char** *Default Value: ""* Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension. Use this field when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate. The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator. **Curve** *char** *Default Value: ""* Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys. | | | | | --- | --- | --- | | SB_EC_SECP112R1 | SECP112R1 | | | SB_EC_SECP112R2 | SECP112R2 | | | SB_EC_SECP128R1 | SECP128R1 | | | SB_EC_SECP128R2 | SECP128R2 | | | SB_EC_SECP160K1 | SECP160K1 | | | SB_EC_SECP160R1 | SECP160R1 | | | SB_EC_SECP160R2 | SECP160R2 | | | SB_EC_SECP192K1 | SECP192K1 | | | SB_EC_SECP192R1 | SECP192R1 | | | SB_EC_SECP224K1 | SECP224K1 | | | SB_EC_SECP224R1 | SECP224R1 | | | SB_EC_SECP256K1 | SECP256K1 | | | SB_EC_SECP256R1 | SECP256R1 | | | SB_EC_SECP384R1 | SECP384R1 | | | SB_EC_SECP521R1 | SECP521R1 | | | SB_EC_SECT113R1 | SECT113R1 | | | SB_EC_SECT113R2 | SECT113R2 | | | SB_EC_SECT131R1 | SECT131R1 | | | SB_EC_SECT131R2 | SECT131R2 | | | SB_EC_SECT163K1 | SECT163K1 | | | SB_EC_SECT163R1 | SECT163R1 | | | SB_EC_SECT163R2 | SECT163R2 | | | SB_EC_SECT193R1 | SECT193R1 | | | SB_EC_SECT193R2 | SECT193R2 | | | SB_EC_SECT233K1 | SECT233K1 | | | SB_EC_SECT233R1 | SECT233R1 | | | SB_EC_SECT239K1 | SECT239K1 | | | SB_EC_SECT283K1 | SECT283K1 | | | SB_EC_SECT283R1 | SECT283R1 | | | SB_EC_SECT409K1 | SECT409K1 | | | SB_EC_SECT409R1 | SECT409R1 | | | SB_EC_SECT571K1 | SECT571K1 | | | SB_EC_SECT571R1 | SECT571R1 | | | SB_EC_PRIME192V1 | PRIME192V1 | | | SB_EC_PRIME192V2 | PRIME192V2 | | | SB_EC_PRIME192V3 | PRIME192V3 | | | SB_EC_PRIME239V1 | PRIME239V1 | | | SB_EC_PRIME239V2 | PRIME239V2 | | | SB_EC_PRIME239V3 | PRIME239V3 | | | SB_EC_PRIME256V1 | PRIME256V1 | | | SB_EC_C2PNB163V1 | C2PNB163V1 | | | SB_EC_C2PNB163V2 | C2PNB163V2 | | | SB_EC_C2PNB163V3 | C2PNB163V3 | | | SB_EC_C2PNB176W1 | C2PNB176W1 | | | SB_EC_C2TNB191V1 | C2TNB191V1 | | | SB_EC_C2TNB191V2 | C2TNB191V2 | | | SB_EC_C2TNB191V3 | C2TNB191V3 | | | SB_EC_C2ONB191V4 | C2ONB191V4 | | | SB_EC_C2ONB191V5 | C2ONB191V5 | | | SB_EC_C2PNB208W1 | C2PNB208W1 | | | SB_EC_C2TNB239V1 | C2TNB239V1 | | | SB_EC_C2TNB239V2 | C2TNB239V2 | | | SB_EC_C2TNB239V3 | C2TNB239V3 | | | SB_EC_C2ONB239V4 | C2ONB239V4 | | | SB_EC_C2ONB239V5 | C2ONB239V5 | | | SB_EC_C2PNB272W1 | C2PNB272W1 | | | SB_EC_C2PNB304W1 | C2PNB304W1 | | | SB_EC_C2TNB359V1 | C2TNB359V1 | | | SB_EC_C2PNB368W1 | C2PNB368W1 | | | SB_EC_C2TNB431R1 | C2TNB431R1 | | | SB_EC_NISTP192 | NISTP192 | | | SB_EC_NISTP224 | NISTP224 | | | SB_EC_NISTP256 | NISTP256 | | | SB_EC_NISTP384 | NISTP384 | | | SB_EC_NISTP521 | NISTP521 | | | SB_EC_NISTB163 | NISTB163 | | | SB_EC_NISTB233 | NISTB233 | | | SB_EC_NISTB283 | NISTB283 | | | SB_EC_NISTB409 | NISTB409 | | | SB_EC_NISTB571 | NISTB571 | | | SB_EC_NISTK163 | NISTK163 | | | SB_EC_NISTK233 | NISTK233 | | | SB_EC_NISTK283 | NISTK283 | | | SB_EC_NISTK409 | NISTK409 | | | SB_EC_NISTK571 | NISTK571 | | | SB_EC_GOSTCPTEST | GOSTCPTEST | | | SB_EC_GOSTCPA | GOSTCPA | | | SB_EC_GOSTCPB | GOSTCPB | | | SB_EC_GOSTCPC | GOSTCPC | | | SB_EC_GOSTCPXCHA | GOSTCPXCHA | | | SB_EC_GOSTCPXCHB | GOSTCPXCHB | | | SB_EC_BRAINPOOLP160R1 | BRAINPOOLP160R1 | | | SB_EC_BRAINPOOLP160T1 | BRAINPOOLP160T1 | | | SB_EC_BRAINPOOLP192R1 | BRAINPOOLP192R1 | | | SB_EC_BRAINPOOLP192T1 | BRAINPOOLP192T1 | | | SB_EC_BRAINPOOLP224R1 | BRAINPOOLP224R1 | | | SB_EC_BRAINPOOLP224T1 | BRAINPOOLP224T1 | | | SB_EC_BRAINPOOLP256R1 | BRAINPOOLP256R1 | | | SB_EC_BRAINPOOLP256T1 | BRAINPOOLP256T1 | | | SB_EC_BRAINPOOLP320R1 | BRAINPOOLP320R1 | | | SB_EC_BRAINPOOLP320T1 | BRAINPOOLP320T1 | | | SB_EC_BRAINPOOLP384R1 | BRAINPOOLP384R1 | | | SB_EC_BRAINPOOLP384T1 | BRAINPOOLP384T1 | | | SB_EC_BRAINPOOLP512R1 | BRAINPOOLP512R1 | | | SB_EC_BRAINPOOLP512T1 | BRAINPOOLP512T1 | | | SB_EC_CURVE25519 | CURVE25519 | | | SB_EC_CURVE448 | CURVE448 | | **Fingerprint** *char* (read-only)* *Default Value: ""* Contains the fingerprint (a hash imprint) of this certificate. While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used. **FriendlyName** *char* (read-only)* *Default Value: ""* Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names. **Handle** *int64* *Default Value: 0* Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise. When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. ```text pdfSigner.setSigningCertHandle(certMgr.getCertHandle()); ``` **HashAlgorithm** *char** *Default Value: ""* Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use [SigAlgorithm](#Certificate_f_SigAlgorithm) to find out the hash algorithm that is part of the certificate signature. | | | | | --- | --- | --- | | SB_HASH_ALGORITHM_SHA1 | SHA1 | | | SB_HASH_ALGORITHM_SHA224 | SHA224 | | | SB_HASH_ALGORITHM_SHA256 | SHA256 | | | SB_HASH_ALGORITHM_SHA384 | SHA384 | | | SB_HASH_ALGORITHM_SHA512 | SHA512 | | | SB_HASH_ALGORITHM_MD2 | MD2 | | | SB_HASH_ALGORITHM_MD4 | MD4 | | | SB_HASH_ALGORITHM_MD5 | MD5 | | | SB_HASH_ALGORITHM_RIPEMD160 | RIPEMD160 | | | SB_HASH_ALGORITHM_CRC32 | CRC32 | | | SB_HASH_ALGORITHM_SSL3 | SSL3 | | | SB_HASH_ALGORITHM_GOST_R3411_1994 | GOST1994 | | | SB_HASH_ALGORITHM_WHIRLPOOL | WHIRLPOOL | | | SB_HASH_ALGORITHM_POLY1305 | POLY1305 | | | SB_HASH_ALGORITHM_SHA3_224 | SHA3_224 | | | SB_HASH_ALGORITHM_SHA3_256 | SHA3_256 | | | SB_HASH_ALGORITHM_SHA3_384 | SHA3_384 | | | SB_HASH_ALGORITHM_SHA3_512 | SHA3_512 | | | SB_HASH_ALGORITHM_BLAKE2S_128 | BLAKE2S_128 | | | SB_HASH_ALGORITHM_BLAKE2S_160 | BLAKE2S_160 | | | SB_HASH_ALGORITHM_BLAKE2S_224 | BLAKE2S_224 | | | SB_HASH_ALGORITHM_BLAKE2S_256 | BLAKE2S_256 | | | SB_HASH_ALGORITHM_BLAKE2B_160 | BLAKE2B_160 | | | SB_HASH_ALGORITHM_BLAKE2B_256 | BLAKE2B_256 | | | SB_HASH_ALGORITHM_BLAKE2B_384 | BLAKE2B_384 | | | SB_HASH_ALGORITHM_BLAKE2B_512 | BLAKE2B_512 | | | SB_HASH_ALGORITHM_SHAKE_128 | SHAKE_128 | | | SB_HASH_ALGORITHM_SHAKE_256 | SHAKE_256 | | | SB_HASH_ALGORITHM_SHAKE_128_LEN | SHAKE_128_LEN | | | SB_HASH_ALGORITHM_SHAKE_256_LEN | SHAKE_256_LEN | | **Issuer** *char* (read-only)* *Default Value: ""* The common name of the certificate issuer (CA), typically a company name.

[Curve](#Certificate_f_Curve), and [PublicKeyBytes](#Certificate_f_PublicKeyBytes) fields to get more details about the key the certificate contains. **KeyBits** *int (read-only)* *Default Value: 0* Returns the length of the public key in bits. This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the [PublicKeyBytes](#Certificate_f_PublicKeyBytes) or [PrivateKeyBytes](#Certificate_f_PrivateKeyBytes) field would typically contain auxiliary values, and therefore be longer. **KeyFingerprint** *char* (read-only)* *Default Value: ""* Returns a SHA1 fingerprint of the public key contained in the certificate. Note that the key fingerprint is different from the certificate fingerprint accessible via the [Fingerprint](#Certificate_f_Fingerprint) field. The key fingerprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key. **KeyUsage** *int* *Default Value: 0* Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set. This value is a bit mask of the following values: | | | | | --- | --- | --- | | ckuUnknown | 0x00000 | Unknown key usage | | ckuDigitalSignature | 0x00001 | Digital signature | | ckuNonRepudiation | 0x00002 | Non-repudiation | | ckuKeyEncipherment | 0x00004 | Key encipherment | | ckuDataEncipherment | 0x00008 | Data encipherment | | ckuKeyAgreement | 0x00010 | Key agreement | | ckuKeyCertSign | 0x00020 | Certificate signing | | ckuCRLSign | 0x00040 | Revocation signing | | ckuEncipherOnly | 0x00080 | Encipher only | | ckuDecipherOnly | 0x00100 | Decipher only | | ckuServerAuthentication | 0x00200 | Server authentication | | ckuClientAuthentication | 0x00400 | Client authentication | | ckuCodeSigning | 0x00800 | Code signing | | ckuEmailProtection | 0x01000 | Email protection | | ckuTimeStamping | 0x02000 | Timestamping | | ckuOCSPSigning | 0x04000 | OCSP signing | | ckuSmartCardLogon | 0x08000 | Smartcard logon | | ckuKeyPurposeClientAuth | 0x10000 | Kerberos - client authentication | | ckuKeyPurposeKDC | 0x20000 | Kerberos - KDC | Set this field before generating the certificate to propagate the key usage flags to the new certificate. **KeyValid** *int (read-only)* *Default Value: FALSE* Returns *True* if the certificate's key is cryptographically valid, and *False* otherwise. **OCSPLocations** *char** *Default Value: ""* Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA. Set this field before calling the certificate manager's [Generate](CertificateManager.md#CertificateManager_m_Generate) method to propagate it to the new certificate. The OCSP locations are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator. **OCSPNoCheck** *int* *Default Value: FALSE* Accessor to the value of the certificate's ocsp-no-check extension. **Origin** *int (read-only)* *Default Value: 0* Returns the location that the certificate was taken or loaded from. **PolicyIDs** *char** *Default Value: ""* Contains identifiers (OIDs) of the applicable certificate policies. The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage. Set this field when generating a certificate to propagate the policies information to the new certificate. The policies are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the policy element separator. **PrivateKeyBytes** *char* (read-only)* *Default Value: * Returns the certificate's private key in DER-encoded format. It is normal for this field to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices. **PrivateKeyExists** *int (read-only)* *Default Value: FALSE* Indicates whether the certificate has a usable private key associated with it. If it is set to *True*, the certificate can be used for private key operations, such as signing or decryption. This field is independent from [PrivateKeyBytes](#Certificate_f_PrivateKeyBytes), and can be set to *True* even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations. **PrivateKeyExtractable** *int (read-only)* *Default Value: FALSE* Indicates whether the private key is extractable (exportable). **PublicKeyBytes** *char* (read-only)* *Default Value: * Contains the certificate's public key in DER format. This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate. **Qualified** *int (read-only)* *Default Value: FALSE* Indicates whether the certificate is qualified. This property is set to *True* if the certificate is confirmed by a Trusted List to be qualified. **QualifiedStatements** *int* *Default Value: 0* Returns a simplified qualified status of the certificate. **Qualifiers** *char* (read-only)* *Default Value: ""* A list of qualifiers. Contains a comma-separated list of qualifier aliases for the certificate, for example *QCP-n-qscd,QCWithSSCD*. **SelfSigned** *int (read-only)* *Default Value: FALSE* Indicates whether the certificate is self-signed (root) or signed by an external CA. **SerialNumber** *char** *Default Value: * Returns the certificate's serial number. The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building. **SigAlgorithm** *char* (read-only)* *Default Value: ""* Indicates the algorithm that was used by the CA to sign this certificate. A signature algorithm typically combines hash and public key algorithms together, such as *sha256WithRSAEncryption* or *ecdsa-with-SHA256*. **Source** *int (read-only)* *Default Value: 0* Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response. **Subject** *char* (read-only)* *Default Value: ""* The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via [SubjectRDN](#Certificate_f_SubjectRDN). **SubjectAlternativeName** *char** *Default Value: ""* Returns or sets the value of the Subject Alternative Name extension of the certificate. Subject alternative names are used to provide additional names that are impractical to store in the main [SubjectRDN](#Certificate_f_SubjectRDN) field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect. The alternative names are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the element separator. **SubjectKeyID** *char** *Default Value: * Contains a unique identifier of the certificate's cryptographic key. Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building. The [SubjectKeyID](#Certificate_f_SubjectKeyID) and [CAKeyID](#Certificate_f_CAKeyID) fields of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity. **SubjectRDN** *char** *Default Value: ""* A list of *Property=Value* pairs that uniquely identify the certificate holder (subject). Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data. Example: */C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins*. **Valid** *int (read-only)* *Default Value: FALSE* Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request. **ValidFrom** *char** *Default Value: ""* The time point at which the certificate becomes valid, in UTC. **ValidTo** *char** *Default Value: ""* The time point at which the certificate expires, in UTC. ## Constructors ```text Certificate() ``` Creates a new object with default field values. # CRL Type Represents a Certificate Revocation List. ## Syntax *SecureBlackboxCRL* (declared in *secureblackbox.h*) ## Remarks CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons. Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations. Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid. The following fields are available: - [Bytes](#CRL_f_Bytes) - [CAKeyID](#CRL_f_CAKeyID) - [EntryCount](#CRL_f_EntryCount) - [Handle](#CRL_f_Handle) - [Issuer](#CRL_f_Issuer) - [IssuerRDN](#CRL_f_IssuerRDN) - [Location](#CRL_f_Location) - [NextUpdate](#CRL_f_NextUpdate) - [SigAlgorithm](#CRL_f_SigAlgorithm) - [Source](#CRL_f_Source) - [TBS](#CRL_f_TBS) - [ThisUpdate](#CRL_f_ThisUpdate) ## Fields **Bytes** *char* (read-only)* *Default Value: * Returns the raw CRL data in DER format. **CAKeyID** *char** *Default Value: * A unique identifier (fingerprint) of the CA certificate's private key, if present in the CRL. **EntryCount** *int (read-only)* *Default Value: 0* Returns the number of certificate status entries in the CRL. **Handle** *int64* *Default Value: 0* Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise. When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. ```text pdfSigner.setSigningCertHandle(certMgr.getCertHandle()); ``` **Issuer** *char* (read-only)* *Default Value: ""* The common name of the CRL issuer (CA), typically a company name. **IssuerRDN** *char* (read-only)* *Default Value: ""* A collection of information, in the form of [OID, Value] pairs, uniquely identifying the CRL issuer. **Location** *char* (read-only)* *Default Value: ""* The URL that the CRL was downloaded from. **NextUpdate** *char** *Default Value: ""* The planned time and date of the next version of this CRL to be published. **SigAlgorithm** *char** *Default Value: "0"* The public key algorithm that was used by the CA to sign this CRL. **Source** *int (read-only)* *Default Value: 0* Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response. **TBS** *char* (read-only)* *Default Value: * The to-be-signed part of the CRL (the CRL without the signature part). **ThisUpdate** *char** *Default Value: ""* The date and time at which this version of the CRL was published. ## Constructors ```text CRL() ``` Creates an empty CRL object. # 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. The following fields are available: - [AsyncDocumentID](#ExternalCrypto_f_AsyncDocumentID) - [CustomParams](#ExternalCrypto_f_CustomParams) - [Data](#ExternalCrypto_f_Data) - [ExternalHashCalculation](#ExternalCrypto_f_ExternalHashCalculation) - [HashAlgorithm](#ExternalCrypto_f_HashAlgorithm) - [KeyID](#ExternalCrypto_f_KeyID) - [KeySecret](#ExternalCrypto_f_KeySecret) - [Method](#ExternalCrypto_f_Method) - [Mode](#ExternalCrypto_f_Mode) - [PublicKeyAlgorithm](#ExternalCrypto_f_PublicKeyAlgorithm) ## 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_SHA1 | SHA1 | | | SB_HASH_ALGORITHM_SHA224 | SHA224 | | | SB_HASH_ALGORITHM_SHA256 | SHA256 | | | SB_HASH_ALGORITHM_SHA384 | SHA384 | | | SB_HASH_ALGORITHM_SHA512 | SHA512 | | | SB_HASH_ALGORITHM_MD2 | MD2 | | | SB_HASH_ALGORITHM_MD4 | MD4 | | | SB_HASH_ALGORITHM_MD5 | MD5 | | | SB_HASH_ALGORITHM_RIPEMD160 | RIPEMD160 | | | SB_HASH_ALGORITHM_CRC32 | CRC32 | | | SB_HASH_ALGORITHM_SSL3 | SSL3 | | | SB_HASH_ALGORITHM_GOST_R3411_1994 | GOST1994 | | | SB_HASH_ALGORITHM_WHIRLPOOL | WHIRLPOOL | | | SB_HASH_ALGORITHM_POLY1305 | POLY1305 | | | SB_HASH_ALGORITHM_SHA3_224 | SHA3_224 | | | SB_HASH_ALGORITHM_SHA3_256 | SHA3_256 | | | SB_HASH_ALGORITHM_SHA3_384 | SHA3_384 | | | SB_HASH_ALGORITHM_SHA3_512 | SHA3_512 | | | SB_HASH_ALGORITHM_BLAKE2S_128 | BLAKE2S_128 | | | SB_HASH_ALGORITHM_BLAKE2S_160 | BLAKE2S_160 | | | SB_HASH_ALGORITHM_BLAKE2S_224 | BLAKE2S_224 | | | SB_HASH_ALGORITHM_BLAKE2S_256 | BLAKE2S_256 | | | SB_HASH_ALGORITHM_BLAKE2B_160 | BLAKE2B_160 | | | SB_HASH_ALGORITHM_BLAKE2B_256 | BLAKE2B_256 | | | SB_HASH_ALGORITHM_BLAKE2B_384 | BLAKE2B_384 | | | SB_HASH_ALGORITHM_BLAKE2B_512 | BLAKE2B_512 | | | SB_HASH_ALGORITHM_SHAKE_128 | SHAKE_128 | | | SB_HASH_ALGORITHM_SHAKE_256 | SHAKE_256 | | | SB_HASH_ALGORITHM_SHAKE_128_LEN | SHAKE_128_LEN | | | SB_HASH_ALGORITHM_SHAKE_256_LEN | SHAKE_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 [KeySecret](#ExternalCrypto_f_KeySecret) 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: ```text 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 [KeyID](#ExternalCrypto_f_KeyID) topic. **Method** *int* *Default Value: 0* Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup. Available options: | | | | --- | --- | | asmdPKCS1 | 0 | | asmdPKCS7 | 1 | **Mode** *int* *Default Value: 0* Specifies the external cryptography mode. Available options: | | | | --- | --- | | ecmDefault | The default value (0) | | ecmDisabled | Do not use DC or external signing (1) | | ecmGeneric | Generic external signing with the OnExternalSign event (2) | | ecmDCAuth | DCAuth signing (3) | | ecmDCAuthJSON | DCAuth 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. | | | | | --- | --- | --- | | SB_CERT_ALGORITHM_ID_RSA_ENCRYPTION | rsaEncryption | | | SB_CERT_ALGORITHM_MD2_RSA_ENCRYPTION |

The following options are available: | | | | | --- | --- | --- | | crapmCompatible | 0 | TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled). | | crapmStrict | 1 | Renegotiation attack prevention is enabled and enforced. | | crapmAuto | 2 | Automatically choose whether to enable or disable renegotiation attack prevention. | **RevocationCheck** *int* *Default Value: 1* Specifies the kind(s) of revocation check to perform. Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information. | | | | | --- | --- | --- | | crcNone | 0 | No revocation checking. | | crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. | | crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. | | crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. | | crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. | | crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. | | crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. | | crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. | | crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. | This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time. There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs). This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential. NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable. NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails. **SSLOptions** *int* *Default Value: 16* Various SSL (TLS) protocol options, set of | | | | | --- | --- | --- | | cssloExpectShutdownMessage | 0x001 | Wait for the close-notify message when shutting down the connection | | cssloOpenSSLDTLSWorkaround | 0x002 | (DEPRECATED) Use a DTLS version workaround when talking to very old OpenSSL versions | | cssloDisableKexLengthAlignment | 0x004 | Do not align the client-side PMS by the RSA modulus size.

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. | | 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. | | 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. | # SecureBlackboxStream Type ## Syntax *SecureBlackboxStream* (declared in *secureblackbox.h*) ## Remarks The TLSClient 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 TLSClient 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. ```text bool CanRead() { return true; } ``` ```text bool CanSeek() { return true; } ``` ```text bool CanWrite() { return true; } ``` ```text int64 GetLength() = 0; ``` ```text void Close() {} ``` ```text int Flush() { return 0; } ``` ```text int Read(void* buffer, int count) = 0; ``` ```text int64 Seek(int64 offset, int seekOrigin) = 0; ``` ```text int Write(const void* buffer, int count) = 0; ``` | | | | --- | --- | | Properties | | | CanRead | Whether the stream supports reading. | | CanSeek | Whether the stream supports seeking. | | CanWrite | Whether the stream supports writing. | | Length | Gets the length of the stream, in bytes. | | Methods | | | Close | Closes the stream, releasing all resources currently allocated for it. This method is called automatically when a SecureBlackboxStream object is deleted. | | Flush | Forces all data held by the stream's buffers to be written out to storage. Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0. | | Read | Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read. Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed. | | Seek | Sets the current position within the stream based on a particular point of origin. Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are: 0: Seek from beginning. 1: Seek from current position. 2: Seek from end. Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported. | | Write | Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written. Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed. | # Config Settings ([TLSClient](#tlsclient-class) 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](#config-method-tlsclient-class) method. ### TLSClient Config Settings **CachedCRLMaxAge**: Specifies the maximum age of a cached CRL.Use this setting to specify the maximum number of seconds that may pass since a CRL was added to the global cache. When the cached CRL is older than this value, it is disregarded and a new CRL should be fetched. The default value is 0, which disables the absolute CRL age check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings. **CachedCRLMaxAgeRatio**: Specifies the maximum age of a cached CRL as a percentage of its remaining lifetime.Use this setting to specify the percentage of the CRL's remaining lifetime, measured from the time the CRL was added to the global cache to the CRL's NextUpdate. When this portion of the remaining lifetime has passed, the cached CRL is disregarded and a new CRL should be fetched. The default value is 0, which disables the CRL ratio check. Values are interpreted in the 0..100 range. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings. **CachedCRLOverlapTime**: Specifies the time period before a cached CRL's NextUpdate when it is considered stale and must be refreshed.Use this setting to specify the number of seconds before the NextUpdate time at which the cached CRL should be disregarded, and a new CRL should be fetched. The default value is 0, which disables the CRL overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings. This setting is evaluated independently from [CachedCRLMaxAge](#CachedCRLMaxAge) and [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio). If several cached CRL freshness settings are enabled, the cached CRL is used only if it satisfies all of them. **CachedOCSPResponseMaxAge**: Specifies the maximum age of a cached OCSP response.Use this setting to specify the maximum number of seconds that may pass since an OCSP response was added to the global cache. When the cached OCSP response is older than this value, it is disregarded and a new OCSP response should be fetched. The default value is 0, which disables the absolute OCSP response age check. This setting is also used to limit open-ended OCSP responses that do not have NextUpdate. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings. **CachedOCSPResponseMaxAgeRatio**: Specifies the maximum age of a cached OCSP response as a percentage of its remaining lifetime.Use this setting to specify the percentage of the OCSP response's remaining lifetime, measured from the time the OCSP response was added to the global cache to the response's NextUpdate. When this portion of the remaining lifetime has passed, the cached OCSP response is disregarded and a new OCSP response should be fetched. The default value is 0, which disables the OCSP response ratio check. Values are interpreted in the 0..100 range. Open-ended OCSP responses without NextUpdate ignore this setting; use [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) to limit their age. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings. **CachedOCSPResponseOverlapTime**: Specifies the time period before a cached OCSP response's NextUpdate when it is considered stale and must be refreshed.Use this setting to specify the number of seconds before the NextUpdate time at which the cached OCSP response should be disregarded, and a new OCSP response should be fetched. The default value is 0, which disables the OCSP response overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings. This setting is evaluated independently from [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio). If several cached OCSP response freshness settings are enabled, the cached OCSP response is used only if it satisfies all of them. **DeltaCRLPreference**: Specifies whether complete or delta CRLs are preferred.Use this setting to specify which CRL type should be preferred during TLS certificate revocation checks. The default value is **dcrlpPreferDelta** (0). Supported values: - **dcrlpPreferDelta** (0): retrieve and use delta CRLs when available, falling back to complete CRLs when needed. - **dcrlpPreferComplete** (1): try complete CRLs first, and use delta CRLs only if complete CRLs cannot be retrieved. **EvaluateSystemTrust**: Enables or disables usage of the platform's built-in trust validation facilities.Enable this property to delegate the chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms). This functionality is currently available on macOS and iOS systems only. This property is enabled by default. **IgnoreSystemTrust**: Whether trusted Windows Certificate Stores should be treated as trusted.Specifies whether, during chain validation, the class should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the class should trust the certificates residing in the Trusted Root Certification Authorities store. If [IgnoreSystemTrust](#IgnoreSystemTrust) is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the [TrustedCertificates](#trustedcertificates-property-tlsclient-class) property) are considered trusted. **RevocationCacheAgePolicy**: Specifies a preset policy for cached CRL and OCSP response freshness settings.Use this setting to configure all cached revocation freshness settings at once. The default value is Disabled. Supported values are case-insensitive: | | | | --- | --- | | Disabled | Sets [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) to 0. This value is the default. It only disables the cache-age freshness policy; it does not disable revocation checking or use of the revocation cache. | | Default | Applies the component default freshness settings. For this component, Default is equivalent to Disabled. | | Short | Uses crl:43200;50;300,ocsp:1800;50;300. This means: CRL maximum age 12 hours, CRL age ratio 50%, CRL overlap 5 minutes; OCSP response maximum age 30 minutes, OCSP response age ratio 50%, OCSP response overlap 5 minutes. | | Long | Uses crl:518400;50;3600,ocsp:21600;50;3600. This means: CRL maximum age 6 days, CRL age ratio 50%, CRL overlap 1 hour; OCSP response maximum age 6 hours, OCSP response age ratio 50%, OCSP response overlap 1 hour. | | N | Interprets N as an integer number of seconds. The overlap settings are set to N seconds, CRL maximum age is set to N * 144, OCSP response maximum age is set to N * 6, and both ratio settings are set to 50. | | crl:;;,ocsp:;; | Sets the CRL and OCSP response freshness values explicitly. | Ratios must be in the 0..100 range. Maximum age and overlap values must be non-negative. Short and Long are time-scale profiles: Long allows older cached revocation information by increasing maximum ages, but also uses a larger pre-expiry safety margin by increasing overlap times. For individual [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) settings, a value of 0 disables the corresponding freshness check. The individual settings remain available for advanced configuration and can be used after this setting to override specific values. **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: | | | | | --- | --- | --- | | none | | No static DNS rules (default) | | local | | Local static DNS rules | | global | | Global 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 divided 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. **TLSCiphersuites**: Returns the list of ciphersuites activated in the component for the current session.Check this property to enumerate the list of TLS ciphersuites enabled in the component. A good place to do that is OnTLSHandshake event handler. **TLSExtensions**: TBD.TBD **TLSGroups**: Returns the list of TLS key exchange groups enabled in the component.Check this property to enumerate the list of TLS key exchange groups enabled in the component. **TLSPeerExtensions**: TBD.TBD **TLSSessionGroup**: Specifies the group name of TLS sessions to be used for session resumption.Use this property to limit the search of cached 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.
