 secureblackbox_xmlsigner_do_signasyncend($res, $asyncreply);
 secureblackbox_xmlsigner_do_signexternal($res);

Remarks

To sign the data, you need to specify the data to be signed using the References property, then select the signature type and signature method type (signature or MAC).

Set the path to the file to be signed via the InputFile. Signed data will be saved in the OutputFile. Finally, call the Sign method to generate a signature and save signed data. It is possible to generate a signature remotely: use SignExternal method to do this.

Asynchronous signing is also supported. Call SignAsyncBegin to generate a signature and save the generated XML-DSIG without signature value into the document. To complete the signing, call SignAsyncEnd.

XMLSigner only performs basic signing of XML documents. For richer features, such as XAdES and/or chain validation, please see the XAdESSigner class

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";

Signs an XML document.

Object Oriented Interface

public function doSign();

Procedural Interface

secureblackbox_xmlsigner_do_sign($res);

Remarks

Call this method to generate a signature over an XML document.

SignAsyncBegin Method (SecureBlackbox_XMLSigner Class)

Initiates the asynchronous signing operation.

Object Oriented Interface

public function doSignAsyncBegin();

Procedural Interface

secureblackbox_xmlsigner_do_signasyncbegin($res);

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. The DC protocol is based on the 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 class), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

SignAsyncEnd Method (SecureBlackbox_XMLSigner Class)

Completes the asynchronous signing operation.

Object Oriented Interface

public function doSignAsyncEnd($asyncreply);

Procedural Interface

secureblackbox_xmlsigner_do_signasyncend($res, $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 the 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.

The async state produced by the server is then passed to the SignAsyncEnd method.

SignExternal Method (SecureBlackbox_XMLSigner Class)

Signs the document using an external signing facility.

Object Oriented Interface

public function doSignExternal();

Procedural Interface

secureblackbox_xmlsigner_do_signexternal($res);

Remarks

Call this method to delegate the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.

When all preparations are done and hash is computed, the class fires ExternalSign event which allows to pass the hash value for signing.

Error Event (SecureBlackbox_XMLSigner Class)

Reports the details of signing errors.

Object Oriented Interface

public function fireError($param);

Procedural Interface

secureblackbox_xmlsigner_register_callback($res, 1, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'

Remarks

The event is fired in case of exceptional conditions during signing.

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 XML.

ExternalSign Event (SecureBlackbox_XMLSigner Class)

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

Object Oriented Interface

public function fireExternalSign($param);

Procedural Interface

secureblackbox_xmlsigner_register_callback($res, 2, array($this, 'fireExternalSign'));

Parameter List

 'operationid'
 'hashalgorithm'
 'pars'
 '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(); };
