SocketSettings Property (MessageSigner Class)
Manages network connection settings.
Syntax
public SocketSettings getSocketSettings();
Remarks
Use this property to tune up network connection parameters.
This property is read-only.
TimestampServer Property (MessageSigner Class)
The address of the timestamping server.
Syntax
public String getTimestampServer(); public void setTimestampServer(String timestampServer);
Default Value
""
Remarks
Use this property to provide the address of the Time Stamping Authority (TSA) server to be used for timestamping the signature.
SecureBlackbox supports RFC3161-compliant timestamping servers, available via HTTP or HTTPS.
If your timestamping service enforces credential-based user authentication (basic or digest), you can provide the credentials in the same URL:
http://user:password@timestamp.server.com/TsaService
For TSAs using certificate-based TLS authentication, provide the client certificate via the TLSClientChain property.
If this property is left empty, no timestamp will be added to the signature.
Starting from summer 2021 update (Vol. 2), the virtual timestamping service is supported, which allows you to intervene in the timestamping routine and provide your own handling for the TSA exchange. This may be handy if the service that you are requesting timestamps from uses a non-standard TSP protocol or requires special authentication option.
To employ the virtual service, assign an URI of the following format to this property:
virtual://localhost?hashonly=true&includecerts=true&reqpolicy=1.2.3.4.5&halg=SHA256
Subscribe to Notification event to get notified about the virtualized timestamping event. The EventID of the timestamping event is TimestampRequest. Inside the event handler, read the base16-encoded request from the EventParam parameter and forward it to the timestamping authority. Upon receiving the response, pass it back to the component, encoded in base16, via the TimestampResponse config property:
component.Config("TimestampResponse=308208ab...");
Note that all the exchange with your custom TSA should take place within the same invocation of the Notification event.
The hashonly parameter of the virtual URI tells the component to only return the timestamp message imprint via the EventParam parameter. If set to false, EventParam will contain the complete RFC3161 timestamping request.
The includecerts parameter specifies that the requestCertificates parameter of the timestamping request should be set to true.
The reqpolicy parameter lets you specify the request policy, and the halg parameter specifies the hash algorithm to use for timestamping.
All the parameters are optional.
TLSClientChain Property (MessageSigner Class)
The TLS client certificate chain.
Syntax
public CertificateList getTLSClientChain(); public void setTLSClientChain(CertificateList TLSClientChain);
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.
This property is not available at design time.
TLSServerChain Property (MessageSigner Class)
The TLS server's certificate chain.
Syntax
public CertificateList getTLSServerChain();
Remarks
Use this property to access the certificate chain sent by the TLS server.
This property is read-only and not available at design time.
TLSSettings Property (MessageSigner Class)
Manages TLS layer settings.
Syntax
public TLSSettings getTLSSettings();
Remarks
Use this property to tune up the TLS layer parameters.
This property is read-only.
UnsignedAttributes Property (MessageSigner Class)
Custom unsigned attributes to be included in the electronic signature.
Syntax
public SignatureAttributeList getUnsignedAttributes();
Remarks
Signature attributes are used to store auxiliary information in the signature. Values included as unsigned attributes are not covered by the signature and can be changed or removed without affecting the signature.
This property is read-only and not available at design time.
Config Method (Messagesigner Class)
Sets or retrieves a configuration setting.
Syntax
public String config(String configurationString);
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.
Countersign Method (Messagesigner Class)
Countersigns an existing signature.
Syntax
public void countersign();
Remarks
Use this method to certify an existing document signature. Countersigning doesn't alter the existing signatures or the signed document itself.
DoAction Method (Messagesigner Class)
Performs an additional action.
Syntax
public String doAction(String actionID, String actionParams);
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 insencitive) 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;....
ExtractAsyncData Method (Messagesigner Class)
Extracts user data from the DC signing service response.
Syntax
public String extractAsyncData(String asyncReply);
Remarks
Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.
The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to completion async stage.
Sign Method (Messagesigner Class)
Signs the data.
Syntax
public void sign();
Remarks
This method signs the data provided via InputFile (or InputStream) with SigningCertificate, and saves the signature in OutputFile (OutputStream). Set the desired signature variant via SignatureType property.
The class automatically timestamps the created signature if a TimestampServer is provided.
SignAsyncBegin Method (Messagesigner Class)
Initiates the asynchronous signing operation.
Syntax
public String signAsyncBegin();
Remarks
When using the DC framework, call this method to initiate the asynchronous signing process. Upon completion, a pre-signed copy of the document will be saved in OutputFile (or OutputStream). Keep the pre-signed copy somewhere local, and pass the returned string ('the request state') to the DC processor for handling.
Upon receiving the response state from the DC processor, assign the path to the pre-signed copy to InputFile (or InputStream), and call SignAsyncEnd to finalize the signing.
Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.
Use the ExternalCrypto.AsyncDocumentID property to supply a unique document ID to include in the request. This is helpful when creating batches of multiple async requests, as it allows you to pass the whole response batch to SignAsyncEnd and expect it to recover the correct response from the batch automatically.
AsyncState is a message of the distributed cryptography (DC) protocol. DC protocol is based on exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.
In a typical scenario you get a client-side async state from the SignAsyncBegin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth control), which processes it and produces a matching signatures state. The async state produced by the server is then passed to the SignAsyncEnd method.
SignAsyncEnd Method (Messagesigner Class)
Completes the asynchronous signing operation.
Syntax
public void signAsyncEnd(String asyncReply);
Remarks
When using the DC framework, call this method upon receiving the response state from the DC processor to complete the asynchronous signing process.
Before calling this method, assign the path to the pre-signed copy of the document obtained from prior SignAsyncBegin call to InputFile (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to OutputFile (or OutputStream).
Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.
Use the ExternalCrypto.AsyncDocumentID parameter to pass a specific document ID if using batched AsyncReply. If used, it should match the value provided on the pre-signing (SignAsyncBegin) stage.
AsyncState is a message of the distributed cryptography (DC) protocol. DC protocol is based on exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.
In a typical scenario you get a client-side async state from the SignAsyncBegin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth control), which processes it and produces a matching signatures state. The async state produced by the server is then passed to the SignAsyncEnd method.
Timestamp Method (Messagesigner Class)
Timestamps a signature.
Syntax
public void timestamp();
Remarks
This method timestamps an existing PKCS#7 signature with TimestampServer. Pass your existing signature via InputFile (or InputStream), and collect the timestamped variant from OutputFile (OutputStream).
Error Event (Messagesigner Class)
Information about errors during PKCS#7 message signing.
Syntax
public class DefaultMessagesignerEventListener implements MessagesignerEventListener { ... public void error(MessagesignerErrorEvent e) {} ... } public class MessagesignerErrorEvent { public int errorCode; public String description; }
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 Messages section.
ExternalSign Event (Messagesigner Class)
Handles remote or external signing initiated by the SignExternal method or other source.
Syntax
public class DefaultMessagesignerEventListener implements MessagesignerEventListener { ... public void externalSign(MessagesignerExternalSignEvent e) {} ... } public class MessagesignerExternalSignEvent { public String operationId; public String hashAlgorithm; public String pars; public String data; public String signedData; }
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 component via SignedData parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for 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 a .NET RSACryptoServiceProvider class may look like the following:
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 (Messagesigner Class)
This event notifies the application about an underlying control flow event.
Syntax
public class DefaultMessagesignerEventListener implements MessagesignerEventListener { ... public void notification(MessagesignerNotificationEvent e) {} ... } public class MessagesignerNotificationEvent { public String eventID; public String eventParam; }
Remarks
The class fires this event to let the application know about some event, occurrence, or milestone in the component. 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 EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, 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:
BeforeTimestamp | This event is fired before timestamp is requested from the timestamping authority. Use the event handler to modify TSA and HTTP settings. |
TimestampError | This event is only fired if failed to obtain a timestamp from the timestamping authority. The EventParam parameter contains extended error info. |
TimestampRequest | A timestamp is requested from the custom timestamping
authority. This event is only fired if TimestampServer was set to a
virtual:// URI. The EventParam parameter contains the
TSP request (or the plain hash, depending on the value provided to
TimestampServer), in base16, that needs to be sent to the TSA.
Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property. |
TimestampRequest Event (Messagesigner Class)
Fires when the class is ready to request a timestamp from an external TSA.
Syntax
public class DefaultMessagesignerEventListener implements MessagesignerEventListener { ... public void timestampRequest(MessagesignerTimestampRequestEvent e) {} ... } public class MessagesignerTimestampRequestEvent { public String TSA; public String timestampRequest; public String timestampResponse; public boolean suppressDefault; }
Remarks
Subscribe to this event to be intercept timestamp requests. You can use it to override timestamping requests and perform them in your code.
The TSA parameter indicates the timestamping service being used. It matches the value passed to TimestampServer property. Set SuppressDefault parameter to false if you would like to stop the built-in TSA request from going ahead. The built-in TSA request is also not performed if the returned TimestampResponse parameter is not empty.
TLSCertNeeded Event (Messagesigner Class)
Fires when a remote TLS party requests a client certificate.
Syntax
public class DefaultMessagesignerEventListener implements MessagesignerEventListener { ... public void TLSCertNeeded(MessagesignerTLSCertNeededEvent e) {} ... } public class MessagesignerTLSCertNeededEvent { public String host; public String CANames; }
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 (optional, according to the TLS spec) advises on the accepted issuing CAs.
Use the TLSClientChain 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 event for the given host and, if the certificate was accepted, succeeded by the TLSEstablished event.
TLSCertValidate Event (Messagesigner Class)
This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.
Syntax
public class DefaultMessagesignerEventListener implements MessagesignerEventListener { ... public void TLSCertValidate(MessagesignerTLSCertValidateEvent e) {} ... } public class MessagesignerTLSCertValidateEvent { public String serverHost; public String serverIP; public boolean accept; }
Remarks
This event is fired during a TLS handshake. Use TLSServerChain property to access the certificate chain. In general case, components 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 component, and can be adjusted if needed.
TLSEstablished Event (Messagesigner Class)
Fires when a TLS handshake with Host successfully completes.
Syntax
public class DefaultMessagesignerEventListener implements MessagesignerEventListener { ... public void TLSEstablished(MessagesignerTLSEstablishedEvent e) {} ... } public class MessagesignerTLSEstablishedEvent { public String host; public String version; public String ciphersuite; public byte[] connectionId; public boolean abort; }
Remarks
The class uses this event to notify the application about successful completion of a TLS handshake.
The Version, Ciphersuite, and ConnectionId parameters indicate security parameters of the new connection. Use the Abort parameter if you need to terminate the connection at this stage.
TLSHandshake Event (Messagesigner Class)

KeyID String |
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 extra protection layer for the protocol and diminishes the risk of private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use 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.

RevocationCheck int |
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.
This setting controls the way the revocation checks are performed. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential. |

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. |
