The DCAuthWebServer Module offers higher-level access to 'private key side' functionality of SecureBlackbox DC protocol.

Syntax

SecureBlackbox.Dcauthwebserver

Remarks

DCAuthWebServer provides a built-in REST responder for DC requests. Use it in conjunction with the in-browser Javascript that comes with DC package, or with standalone DC requestors. DCAuthWebServer listens to DC requests on a specific Port or a port chosen between PortRangeFrom and PortRangeTo. Use DCAuth, which provides a lower-level access to the signing engine, to implement DC in applications, apps, or services.

Use this property to specify the port number to listen to connections on. Standard port numbers are 80 for an HTTP server, and 443 for an HTTPS server.

Alternatively, you may specify the acceptable range of listening ports via PortRangeFrom and PortRangeTo properties. In this case the port will be allocated within the requested range by the operating system, and reported in BoundPort.

PortRangeFrom Property (DCAuthWebServer Module)

Specifies the lower limit of the listening port range for incoming connections.

Syntax

• Swift
• Objective-C

public var portRangeFrom: Int32 {

When a port range is used to specify the listening port (as opposed to a fixed value provided via Port), the port will be allocated within the requested range by the operating system, and reported in BoundPort.

Note that this property is ignored if the Port property is set to a non-zero value, in which case the server always aims to listen on that fixed port.

PortRangeTo Property (DCAuthWebServer Module)

Specifies the upper limit of the listening port range for incoming connections.

Syntax

• Swift
• Objective-C

public var portRangeTo: Int32 {
  get {...}

- (void)setServerCertHandle:(int)serverCertIndex :(long long)newServerCertHandle;

Default Value

"SecureBlackbox"

Remarks

Use this property to provide a list of TLS certificates for the server endpoint.

A TLS endpoint needs a certificate to be able to accept TLS connections. At least one of the certificates in the collection - the endpoint certificate - must have a private key associated with it.

The collection may include more than one endpoint certificate, and more than one chain. A typical usage scenario is to include two chains (ECDSA and RSA), to cater for clients with different cipher suite preferences.

Example 1: The certificate resides on a PKCS#11 device

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

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 (DCAuthWebServer Module)

The address of the timestamping server.

Syntax

• Swift
• Objective-C

public var timestampServer: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=timestampServer,setter=setTimestampServer:) NSString* timestampServer;

- (NSString*)timestampServer;
- (void)setTimestampServer :(NSString*)newTimestampServer;

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.

- (NSString*)config:(NSString*)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.

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 section.

ExternalSign Event (DCAuthWebServer Module)

Handles remote or external signing initiated by the server protocol.

Syntax

• Swift
• Objective-C

func onExternalSign(connectionID: Int64, operationId: String, hashAlgorithm: String, pars: String, data: String, signedData: inout String)

- (void)onExternalSign:(long long)connectionID :(NSString*)operationId :(NSString*)hashAlgorithm :(NSString*)pars :(NSString*)data :(NSString**)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(); };

KeySecretNeeded Event (DCAuthWebServer Module)

• Swift
• Objective-C

func onKeySecretNeeded(connectionId: Int64, keyId: String, keySecret: inout String)

- (void)onKeySecretNeeded:(long long)connectionId :(NSString*)keyId :(NSString**)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.

Log Event (DCAuthWebServer Module)

Reports a single log line.

Syntax

• Swift
• Objective-C

func onLog(connectionId: Int64, logType: Int32, details: String)

- (void)onLog:(long long)connectionId :(int)logType :(NSString*)details;

SelectCert Event (DCAuthWebServer Module)

Requests certificate selection criteria from the application.

Syntax

• Swift
• Objective-C

func onSelectCert(connectionId: Int64, commonName: inout String, keyID: inout String, keyUsage: inout String, fingerprint: inout String, storeType: inout String)

- (void)onSelectCert:(long long)connectionId :(NSString**)commonName :(NSString**)keyID :(NSString**)keyUsage :(NSString**)fingerprint :(NSString**)storeType;

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 reject the request. Use the SignRequestCompleted event to track completion of the initiated operation.

SignRequestCompleted Event (DCAuthWebServer Module)

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

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 Username parameter matches the parameter in SignRequest event.

TimestampRequest Event (DCAuthWebServer Module)

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

Syntax

• Swift
• Objective-C

func onTimestampRequest(tsa: String, timestampRequest: String, timestampResponse: inout String, suppressDefault: inout Bool)

- (void)onTimestampRequest:(NSString*)TSA :(NSString*)timestampRequest :(NSString**)timestampResponse :(int*)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.

Requests a pre-shared key for TLS-PSK.

Syntax

• Swift
• Objective-C

func onTLSPSK(connectionID: Int64, identity: String, psk: inout String, ciphersuite: inout String)

- (void)onTLSPSK:(long long)connectionID :(NSString*)identity :(NSString**)PSK :(NSString**)ciphersuite;

Remarks

The class fires this event to report that a client has requested a TLS-PSK negotiation. ConnectionId indicates the unique connection ID that requested the PSK handshake.

Use Identity to look up for the corresponding pre-shared key in the server's database, then assign the key to the PSK parameter. If TLS 1.3 PSK is used, you will also need to assign the Ciphersuite parameter with the cipher suite associated with that identity and their key.
