DCAuthWebServer Component
Properties Methods Events Config Settings Errors
The DCAuthWebServer Component offers higher-level access to 'private key side' functionality of SecureBlackbox DC protocol.
Syntax
TsbxDCAuthWebServer
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.

This property lets you specify policies to apply blanketly to the requests. If this property does not give you enough flexibility - for example, if you need to cherry-pick requests basing on their content - please consider using the SignRequest (allows you to track individual requests) and/or ExternalSign (lets you perform the signing manually) events. This setting is a bit mask of the following flags:
| aspAcceptUnsignedRequests | 1 | Allows the component to accept unauthenticated messages (those not signed with KeyID/KeySecret). Use with extreme care. |
| aspIgnorePKCS1Requests | 2 | Ignore requests of PKCS1 type. |
| aspIgnorePKCS7Requests | 4 | Ignore requests of PKCS7 type. |
| aspIgnoreRequestTSA | 8 | Ignore the TSA URL provided in the request, and either stick with the service provided via TimestampServer property, or not timestamp the message altogether. |
| aspIgnoreRequestSigningTime | 16 | Ignore the signing time included in the request. |
| aspIgnoreRequestPKCS7Settings | 32 | Ignore auxiliary PKCS7 settings (content type, attributes) included in the request. |
| aspAlwaysTimestampSigs | 64 | Timestamp created signatures (PKCS7 only), even if the client did not request it. |
This property is not available at design time.
Port Property (DCAuthWebServer Component)
Specifies the port number to listen for connections on.
Syntax
property Port: Integer read get_Port write set_Port;
Default Value
80
Remarks
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 Component)
Specifies the lower limit of the listening port range for incoming connections.
Syntax
property PortRangeFrom: Integer read get_PortRangeFrom write set_PortRangeFrom;
Default Value
0
Remarks
Use this property to specify the lower limit of the port range to listen to connections on. 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 Component)
Specifies the upper limit of the listening port range for incoming connections.
Syntax
property PortRangeTo: Integer read get_PortRangeTo write set_PortRangeTo;
Default Value
0
Remarks
Use this property to specify the upper limit of the port range to listen to connections on. 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.
ServerCertificates Property (DCAuthWebServer Component)
The server's TLS certificates.
Syntax
property ServerCertificates: TsbxCertificateList read get_ServerCertificates write set_ServerCertificates;
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 ciphersuite preferences.
This property is not available at design time.
SessionTimeout Property (DCAuthWebServer Component)
Specifies the default session timeout value in milliseconds.
Syntax
property SessionTimeout: Integer read get_SessionTimeout write set_SessionTimeout;

Syntax
property SignEndpoint: String read get_SignEndpoint write set_SignEndpoint;
Default Value
'/sign'
Remarks
Use this property to specify the signing service end point on the server.
SigningCertificate Property (DCAuthWebServer Component)
The certificate to be used for signing.
Syntax
property SigningCertificate: TsbxCertificate read get_SigningCertificate write set_SigningCertificate;
Remarks

This property is read-only.
StorageId Property (DCAuthWebServer Component)
Specifies the signing certificate residing in an alternative location.
Syntax
property StorageId: String read get_StorageId write set_StorageId;
Default Value
''
Remarks
Use this property to specify the signing certificate contained on alternative media, such as a hardware device or in a system certificate store.
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 Component)
The address of the timestamping server.
Syntax
property TimestampServer: String read get_TimestampServer write set_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.
TLSSettings Property (DCAuthWebServer Component)

This property is not available at design time.
WebsiteName Property (DCAuthWebServer Component)
Specifies the web site name to use in the certificate.
Syntax
property WebsiteName: String read get_WebsiteName write set_WebsiteName;
Default Value
'SecureBlackbox'
Remarks
If using an internally-generated certificate, use this property to specify the web site name to be included as a common name. A typical common name consists of the host name, such as '192.168.10.10' or 'domain.com'.
Config Method (DCAuthWebServer Component)
Sets or retrieves a configuration setting.
Syntax
function Config(ConfigurationString: String): String;
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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 (DCAuthWebServer Component)
Performs an additional action.
Syntax
function DoAction(ActionID: String; ActionParams: String): String;
Remarks
DoAction is a generic method available in every component. 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 of the action is provided in ActionID parameter. ActionParams contains a list of parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

CustomParametersReceived Event (DCAuthWebServer Component)
Passes custom request parameters to the application.
Syntax
type TCustomParametersReceivedEvent = procedure ( Sender: TObject; ConnectionId: Int64; const Value: String ) of Object;
property OnCustomParametersReceived: TCustomParametersReceivedEvent read FOnCustomParametersReceived write FOnCustomParametersReceived;
Remarks
Subscribe to this event to access custom signing parameters supplied by the signer in their request. The Value string contains the parameters as included by the requestor.
Disconnect Event (DCAuthWebServer Component)
Fires to report a disconnected client.
Syntax
type TDisconnectEvent = procedure ( Sender: TObject; ConnectionID: Int64 ) of Object;
property OnDisconnect: TDisconnectEvent read FOnDisconnect write FOnDisconnect;
Remarks
The component fires this event when a connected client disconnects.
Error Event (DCAuthWebServer Component)
Information about errors during data delivery.
Syntax
type TErrorEvent = procedure ( Sender: TObject; ConnectionID: Int64; ErrorCode: Integer; const Description: String ) of Object;
property OnError: TErrorEvent read FOnError write FOnError;
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 section.
ExternalSign Event (DCAuthWebServer Component)
Handles remote or external signing initiated by the server protocol.
Syntax
type TExternalSignEvent = procedure ( Sender: TObject; ConnectionID: Int64; const OperationId: String; const HashAlgorithm: String; const Pars: String; const Data: String; var SignedData: String ) of Object;
property OnExternalSign: TExternalSignEvent read FOnExternalSign write FOnExternalSign;
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 Component)
Requests the key secret from the application.
Syntax
type TKeySecretNeededEvent = procedure ( Sender: TObject; ConnectionId: Int64; const KeyId: String; var KeySecret: String ) of Object;
property OnKeySecretNeeded: TKeySecretNeededEvent read FOnKeySecretNeeded write FOnKeySecretNeeded;
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 Component)

The Method parameter specifies the async signing method requested by the client:
| asmdPKCS1 | 0 |
| asmdPKCS7 | 1 |
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.

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

RevocationCheck TsbxRevocationCheckKinds |
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. |

UserAccount Type
A container for user account information.
Remarks
UserAccount objects are used to store user account information, such as logins and passwords.
Fields
|
AssociatedData TBytes |
Contains the user's Associated Data when SSH AEAD (Authenticated Encryption with Associated Data) algorithm is used. |
|||||||||

|
Handle Int64 |
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.
|
|||||||||
|
HashAlgorithm String |
Specifies the hash algorithm used to generate TOTP (Time-based One-Time Passwords) passwords for this user. Three HMAC algorithms are supported, with SHA-1, SHA-256, and SHA-512 digests:
|
|||||||||
|
IncomingSpeedLimit Integer |
Specifies the incoming speed limit for this user. The value of 0 (zero) means "no limitation". |
|||||||||
|
OtpAlgorithm TsbxOTPAlgorithms |
The algorithm used to generate one-time passwords (OTP) for this user, either HOTP (Hash-based OTP) or TOTP (Time-based OTP). In the former case, a value of a dedicated counter is used to generate a unique password, while in the latter the password is generated on the basis of the current time value.

Config Settings (DCAuthWebServer Component)
The component 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 component, access to these internal properties is provided through the Config method.Base Config Settings | ||||||||||||||||||||||||||||||
| CheckKeyIntegrityBeforeUse:
Enables or disable private key integrity check before use.This global property enables or disables private key material check before each signing operation. This slows down performance a bit,
but prevents a selection of attacks on RSA keys where keys with unknown origins are used.
You can switch this property off to improve performance if your project only uses known, good private keys. |
||||||||||||||||||||||||||||||
| CookieCaching:
Specifies whether a cookie cache should be used for HTTP(S) transports.Set this property to enable or disable cookies caching for the component.
Supported values are:
|
||||||||||||||||||||||||||||||
| Cookies: Gets or sets local cookies for the component (supported for HTTPClient, RESTClient and SOAPClient only).Use this property to get cookies from the internal cookie storage of the component and/or restore them back between application sessions. | ||||||||||||||||||||||||||||||
| DefDeriveKeyIterations: Specifies the default key derivation algorithm iteration count.This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided. | ||||||||||||||||||||||||||||||
| EnableClientSideSSLFFDHE:
Enables or disables finite field DHE key exchange support in TLS clients.This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower
algorithm if compared to EC DHE; enabling it may result in slower connections.
This setting only applies to sessions negotiated with TLS version 1.3. |
||||||||||||||||||||||||||||||
| GlobalCookies: Gets or sets global cookies for all the HTTP transports.Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the components that have its CookieCaching property set to "global". | ||||||||||||||||||||||||||||||
| HttpUserAgent: Specifies the user agent name to be used by all HTTP clients.This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other components. | ||||||||||||||||||||||||||||||
| LogDestination:
Specifies the debug log destination.Contains a comma-separated list of values that specifies where debug log should be dumped.
Supported values are:
|
||||||||||||||||||||||||||||||
| LogDetails:
Specifies the debug log details to dump.Contains a comma-separated list of values that specifies which debug log details to dump.
Supported values are:
|
||||||||||||||||||||||||||||||
| LogFile: Specifies the debug log filename.Use this property to provide a path to the log file. | ||||||||||||||||||||||||||||||
| LogFilters:
Specifies the debug log filters.Contains a comma-separated list of value pairs ("name:value") that describe filters.
Supported filter names are:
|
||||||||||||||||||||||||||||||
LogFlushMode:
Specifies the log flush mode.Use this property to set the log flush mode. The following values are defined:
|
||||||||||||||||||||||||||||||
| LogLevel:
Specifies the debug log level.Use this property to provide the desired debug log level.
Supported values are:
|
||||||||||||||||||||||||||||||
| LogMaxEventCount:
Specifies the maximum number of events to cache before further action is taken.Use this property to specify the log event number threshold. This threshold may have different effects,
depending on the rotation setting and/or the flush mode.
The default value of this setting is 100. |
||||||||||||||||||||||||||||||
LogRotationMode:
Specifies the log rotation mode.Use this property to set the log rotation mode. The following values are defined:
|
||||||||||||||||||||||||||||||
| MaxASN1BufferLength: Specifies the maximal allowed length for ASN.1 primitive tag data.This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks. | ||||||||||||||||||||||||||||||
| MaxASN1TreeDepth: Specifies the maximal depth for processed ASN.1 trees.This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks. | ||||||||||||||||||||||||||||||
| OCSPHashAlgorithm: Specifies the hash algorithm to be used to identify certificates in OCSP requests.This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful. | ||||||||||||||||||||||||||||||
| StaticDNS:
Specifies whether static DNS rules should be used.Set this property to enable or disable static DNS rules for the component. Works only if UseOwnDNSResolver is set to true.
Supported values are:
|
||||||||||||||||||||||||||||||
| 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 component) 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 devided 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 component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component 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. | ||||||||||||||||||||||||||||||
| Tag: Allows to store any custom data.Use this config property to store any custom data. | ||||||||||||||||||||||||||||||
| 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. |
||||||||||||||||||||||||||||||
| UseSystemRandom: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation. |
