Remarks

The purpose of DCAuth is to sign async requests produced by SignAsyncBegin calls. For each incoming async request containing a document hash, DCAuth produces the corresponding async response containing a signature over that hash.

Protocol Overview

The distributed cryptography protocol involves two principal parties. The signing party, represented by classes such as PDFSigner, XAdESSigner, or OfficeSigner, pre-signs documents (such as PDF files), and encapsulates their hashes into what is called an async request. It then communicates the async request to the private key side, where the DCAuth class extracts the hash and signs it with a local private key. DCAuth then encapsulates the signature into an async response, which is sent back to the signing party. The signing party completes the signing operation by extracting the signature from the async response and embedding it into the pre-signed document.

The protocol supports a variety of uses. The scheme above describes the most typical of them, where the signing party is represented by a web application, and the private key side is represented by a workstation. In that particular scenario DC provides a mechanism for the web app to sign documents residing on the web server with private keys residing on the users workstations, perhaps in non-exportable form (e.g. a USB dongle). Other uses include creation of a signing server for a team of driver developers, or an automated signing gateway for outgoing official documents.

In the webapp-to-browser setting the DCAuth control would normally be used within a web server running on the users workstation. That web server would accept async requests from the web page running in the browser, use DCAuth to generate the matching async response, and feed that response back to the web page. The web page will then submit it back to the web server.

Configuring and Using DCAuth

To process an async request, you need to set up a DCAuth object first, and then call its ProcessRequest method:

• Set the KeyId and KeySecret properties so they match the credentials used by the signing party - e.g. those of PDFSigner object: DCAuth.KeyId = "mykeyid"; DCAuth.KeySecret = "mykeysecret123";

  These two properties are used to verify the integrity of the incoming async requests. Keep them safe.

• Provide the signing certificate: DCAuth.SigningCertificate = "C:\Certs\SigningCert.pfx"; DCAuth.CertPassword = "password789";

  Alternatively, use StorageId to provide a certificate residing elsewhere, such as a PKCS#11 device.

• Assign the async request to the Input property: DCAuth.Input = Request;

  Make sure to provide the request in its original XML format. Some technologies and SecureBlackbox code samples may apply additional encoding when conveying async requests from their origin to the DCAuth endpoint. Please double check that you assign the request without any encodings applied. An async request is a properly formed XML document with the root element of SecureBlackboxAsyncState.

• Call the ProcessRequest method: DCAuth.ProcessRequest;

  This method performs the actual signing of the hash. Make sure your code is prepared for potential signing errors.

• If the ProcessRequest call has succeeded, grab the async response from the Output property: Result = DCAuth.Output;

Please see the demo folder for more in-depth code examples of this class.

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 ExternalCryptoKeySecret to pass the key itself.

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

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

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

Data Type

Example 2: The certificate resides in a system store

system://localmachine@/?store=MY

You can use the following URI modifiers to provide more accurate specifiers for the needed certificate:

• cn: the common name of the certificate subject.
• keyid: the unique identifier included in subject key identifier extension of the certificate.
• keyusage: a comma-separated list of enabled (+) or disabled (-) key usages. The following usages are supported: signature, nonrepudiation, keyencipherment, dataencipherment, keyagreement, keycertsign, crlsign, encipheronly, decipheronly, serverauth, clientauth, codesigning, emailprotection, timestamping, ocspsigning, smartcardlogon, keypurposeclientauth, keypurposekdc.
• fingerprint: the fingerprint of the certificate.

Example 3: selecting the certificate with a given fingerprint:

pkcs11://user:pin@/c:/windows/system32/pkcsdriver.dll?slot=0&readonly=1&fingerprint=001122334455667788aabbccddeeff0011223344

TimestampServer Property (SecureBlackbox_DCAuth Class)

The address of the timestamping server.

Object Oriented Interface

public function getTimestampServer();


public function setTimestampServer($value);

Procedural Interface

secureblackbox_dcauth_get($res, 113 );


secureblackbox_dcauth_set($res, 113, $value );

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.

Default Value

1

Remarks

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 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.

This property is not available at design time.

Config Method (SecureBlackbox_DCAuth Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

secureblackbox_dcauth_do_config($res, $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.

DoAction Method (SecureBlackbox_DCAuth Class)

Performs an additional action.

Object Oriented Interface

public function doDoAction($actionid, $actionparams);

Procedural Interface

secureblackbox_dcauth_do_doaction($res, $actionid, $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 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;....

ProcessRequest Method (SecureBlackbox_DCAuth Class)

Processes the request.

Object Oriented Interface

public function doProcessRequest();

Procedural Interface

secureblackbox_dcauth_do_processrequest($res);

Remarks

Use this method to process the request, sign the hashes, and produce the response. This is the main method of the class. Note that a single request received from the counterparty may contain more than one signature request. This method processes them all, reporting each atomic signature request with SignRequest and SignRequestCompleted events. Before calling this method, make sure you assign the request content to Input. Upon completion, read the response (containing all the signatures) from Output property.

CustomParametersReceived Event (SecureBlackbox_DCAuth Class)

Passes custom request parameters to the application.

Object Oriented Interface

public function fireCustomParametersReceived($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 1, array($this, 'fireCustomParametersReceived'));

Parameter List

 'value'

Remarks

This event is only provided for backward compatibility and is not currently used.

Error Event (SecureBlackbox_DCAuth Class)

Reports information about errors during request processing or signing.

Object Oriented Interface

public function fireError($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 2, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'

Remarks

The event is fired if an error occurs during the request processing. Use the ErrorCode and Description parameters to get the details.

ExternalSign Event (SecureBlackbox_DCAuth Class)

Handles remote or external signing initiated by the SignExternal method or other source.

Object Oriented Interface

public function fireExternalSign($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 3, array($this, 'fireExternalSign'));

Parameter List

 'operationid'
 'hashalgorithm'
 'pars'
 'methodpars'
 'data'
 '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 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: 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(); };

The MethodPars parameter contains the method-specific parameters. For example, for PKCS7 requests it contains the requested parameters of the PKCS7 blob.

KeySecretNeeded Event (SecureBlackbox_DCAuth Class)

Requests the key secret from the application.

Object Oriented Interface

public function fireKeySecretNeeded($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 4, array($this, 'fireKeySecretNeeded'));

Parameter List

 'keyid'
 'keysecret'

Remarks

Subscribe to this event to pass the key secret (a pre-shared request authentication code) to the signing component when it is needed. The authentication combination consists of the KeyId, a non-secret unique key identifier, and the KeySecret, shared by the parties, which should be kept private. This event is an alternative for KeySecret property. Use it when you expect to process requests from requestors with different KeyIds and secrets. If you only expect to receive requests from a single requestor with a known KeyId, providing the key secret via KeyId and KeySecret properties would be an easier route.

Notification Event (SecureBlackbox_DCAuth Class)

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

Object Oriented Interface

public function fireNotification($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 5, array($this, 'fireNotification'));

Parameter List

 'eventid'
 'eventparam'

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.

ParameterReceived Event (SecureBlackbox_DCAuth Class)

Passes a standard request parameter to the user code.

Object Oriented Interface

public function fireParameterReceived($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 6, array($this, 'fireParameterReceived'));

Parameter List

 'name'
 'value'

Remarks

This event is only provided for backward compatibility and is not currently used.

SignRequest Event (SecureBlackbox_DCAuth Class)

This event signifies the processing of an atomic signing request.

Object Oriented Interface

public function fireSignRequest($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 7, array($this, 'fireSignRequest'));

Parameter List

 'method'
 'hashalgorithm'
 'hash'
 'keyid'
 'pars'
 'methodpars'
 'allow'

Remarks

Subscribe to this event to be notified of every signature request processed by the DC server. Note that any one request coming from the requestor may contain multiple individual signature requests (so-called 'batching'). This event is a good mechanism to track signature requests for accountability purposes, and provide basic access control over the signing operations. The Method parameter specifies the async signing method requested by the client:

The Hash parameter contains the hash, made using HashAlgorithm, that needs to be signed. KeyID contains the key identifier of the requestor.

The Pars string contains a semicolon-separated string of the principal signature parameters. This has the same format and content that is passed to ExternalSign, if it is used. The MethodPars contains a similar parameter string, but for the specific async signing method used. For the PKCS1 method there are no defined method parameters, while the PKCS7 method supports a selection of settings that tune up the CMS blob.

Set Allow to false to stop the request from being served. Use the SignRequestCompleted event to track completion of the initiated operation.

SignRequestCompleted Event (SecureBlackbox_DCAuth Class)

This event signifies completion of the processing of an atomic signing request.

Object Oriented Interface

public function fireSignRequestCompleted($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 8, array($this, 'fireSignRequestCompleted'));

Parameter List

 'method'
 'hashalgorithm'
 'hash'
 'keyid'
 'pars'
 'methodpars'
 'signature'

Remarks

Use this event to track completion of signing request processing. The Hash parameter contains the hash that is signed, as supplied by the requestor, and the Signature parameter contains the resulting cryptographic signature. The KeyID parameter matches the parameter in SignRequest event.

TimestampRequest Event (SecureBlackbox_DCAuth Class)

Fires when the class is ready to request a timestamp from an external TSA.

Object Oriented Interface

public function fireTimestampRequest($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 9, array($this, 'fireTimestampRequest'));

Parameter List

 'tsa'
 'timestamprequest'
 'timestampresponse'
 'suppressdefault'

Remarks

Subscribe to this event to 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 the TimestampServer property. Set the 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 (SecureBlackbox_DCAuth Class)

Fires when a remote TLS party requests a client certificate.

Object Oriented Interface

public function fireTLSCertNeeded($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 10, array($this, 'fireTLSCertNeeded'));

Parameter List

 'host'
 '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 parameter (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 (SecureBlackbox_DCAuth Class)

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

Object Oriented Interface

public function fireTLSCertValidate($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 11, array($this, 'fireTLSCertValidate'));

Parameter List

 'serverhost'
 'serverip'
 'accept'

Remarks

This event is fired during a TLS handshake. Use the TLSServerChain 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 (SecureBlackbox_DCAuth Class)

Fires when a TLS handshake with Host successfully completes.

Object Oriented Interface

public function fireTLSEstablished($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 12, array($this, 'fireTLSEstablished'));

Parameter List

 'host'
 'version'
 'ciphersuite'
 'connectionid'
 'abort'

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 (SecureBlackbox_DCAuth Class)

Fires when a new TLS handshake is initiated, before the handshake commences.

Object Oriented Interface

public function fireTLSHandshake($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 13, array($this, 'fireTLSHandshake'));

Parameter List

 'host'
 'abort'

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 event. If the server chooses to request a client certificate, the TLSCertNeeded event will also be fired.

TLSShutdown Event (SecureBlackbox_DCAuth Class)

Reports the graceful closure of a TLS connection.

Object Oriented Interface

public function fireTLSShutdown($param);

Procedural Interface

secureblackbox_dcauth_register_callback($res, 14, array($this, 'fireTLSShutdown'));

Parameter List

 'host'

Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

Config Settings (DCAuth Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
