Syntax

public CertificateList KnownCertificates { get; }
Public Property KnownCertificates As CertificateList

Remarks

Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.

The purpose of certificates to be added to this collection is roughly equivalent to that of Intermediate Certification Authorities system store in Windows.

Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.

This property is not available at design time.

Please refer to the Certificate type for a complete list of fields.

KnownCRLs Property (WebSocketClient Component)

A list of trusted certificates for chain validation.

Syntax

public CertificateList TrustedCertificates { get; }
Public Property TrustedCertificates As CertificateList

Remarks

Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.

The purpose of this certificate collection is largely the same than that of Windows Trusted Root Certification Authorities system store.

Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.

This property is not available at design time.

Please refer to the Certificate type for a complete list of fields.

UseDigestAuth Property (WebSocketClient Component)

Enables or disables the HTTP Digest authentication.

Syntax

public bool UseDigestAuth { get; set; }
Public Property UseDigestAuth As Boolean

Default Value

UseNTLMAuth Property (WebSocketClient Component)

Enables or disables NTLM authentication.

Syntax

public bool UseNTLMAuth { get; set; }
Public Property UseNTLMAuth As Boolean

Default Value

Remarks

NT LAN Manager (NTLM) authentication relies on Windows credentials to authenticate the user, and requires multiple exchanges between the client and server. Generally it is considered more secure and SSO-friendly than the Digest authentication.

Config Method (WebSocketClient Component)

Sets or retrieves a configuration setting.

Syntax

public string Config(string configurationString);
Public Function Config(ByVal ConfigurationString As String) As 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.

Connect Method (WebSocketClient Component)

Establishes connection to the server.

Syntax

public void Connect(string address);
Public Sub Connect(ByVal Address As String)

Remarks

Call this method to establish remote connection to a server at Address:Port.

Performs an additional action.

Syntax

public string DoAction(string actionID, string actionParams);
Public Function DoAction(ByVal ActionID As String, ByVal ActionParams As String) As 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 (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;....

SendData Method (WebSocketClient Component)

Sends a keep-alive message.

Syntax

public bool SendKeepAlive();
Public Function SendKeepAlive() As Boolean

Remarks

Use this method to send a keep-alive 'ping' to the server. The response, if it comes back, will be reported via the KeepAliveResponse event.

Keep-alive messages provide good means for keeping the connection alive and stay immune to timeouts.

SendText Method (WebSocketClient Component)

Sends a piece of text data to the server.

Syntax

public void SendText(string text);
Public Sub SendText(ByVal Text As String)

Remarks

Use this method to send a piece of text data to the server.

BinaryData Event (WebSocketClient Component)

ExternalSign Event (WebSocketClient Component)

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

Syntax

public event OnExternalSignHandler OnExternalSign;

public delegate void OnExternalSignHandler(object sender, WebsocketclientExternalSignEventArgs e);

public class WebsocketclientExternalSignEventArgs : EventArgs {
  public string OperationId { get; }
  public string HashAlgorithm { get; }
  public string Pars { get; }
  public string Data { get; }
  public string SignedData { get; set; }
}
Public Event OnExternalSign As OnExternalSignHandler

Public Delegate Sub OnExternalSignHandler(sender As Object, e As WebsocketclientExternalSignEventArgs)

Public Class WebsocketclientExternalSignEventArgs Inherits EventArgs
  Public ReadOnly Property OperationId As String
  Public ReadOnly Property HashAlgorithm As String
  Public ReadOnly Property Pars As String
  Public ReadOnly Property Data As String
  Public Property SignedData As String
End Class

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(); };

KeepAliveResponse Event (WebSocketClient Component)

Reports a response to a keep-alive message.

Syntax

Public Class WebsocketclientTLSCertNeededEventArgs Inherits EventArgs
  Public ReadOnly Property Host As String
  Public ReadOnly Property CANames As String
End Class

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.

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.

Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.

Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.

Fields

Bytes
byte[] (read-only)

Default Value: ""

Returns raw CRL data in DER format.

CAKeyID
byte[]

Default Value: ""

A unique identifier (fingerprint) of the CA certificate's private key, if present in the CRL.

EntryCount
int (read-only)

Default Value: 0

Returns the number of certificate status entries in the CRL.

Issuer
string (read-only)

Default Value: ""

The common name of the CRL issuer (CA), typically a company name.

IssuerRDN
string (read-only)

Default Value: ""

A collection of information, in the form of [OID, Value] pairs, uniquely identifying the CRL issuer.

Location
string (read-only)

Default Value: ""

The URL that the CRL was downloaded from.

NextUpdate
string (read-only)

Default Value: ""

The planned time and date of the next version of this CRL to be published.

SigAlgorithm
string (read-only)

Default Value: "0"

The public key algorithm that was used by the CA to sign this CRL.

TBS
byte[] (read-only)

Default Value: ""

The to-be-signed part of the CRL (the CRL without the signature part).

ThisUpdate
string (read-only)

Default Value: ""

The date and time at which this version of the CRL was published.

Constructors

public CRL(byte[] bytes, int startIndex, int count);
Public CRL(ByVal Bytes As Byte(), ByVal StartIndex As Integer, ByVal Count As Integer)

Creates a CRL object from a memory buffer. Bytes is a buffer containing raw (DER) CRL data, StartIndex and Count specify the starting position and the length of the CRL data in the buffer, respectively.

public CRL(string location);
Public CRL(ByVal Location As String)

Creates a CRL object by downloading it from a remote location.

public CRL(System.IO.Stream stream);

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

AsyncDocumentID
string

Default Value: ""

Specifies an optional document ID for SignAsyncBegin() and SignAsyncEnd() calls.

Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. On the completion stage, this value helps the signing component identify the correct signature in the returned batch of responses.

If using batched requests, make sure to set this property to the same value on both pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

CustomParams
string

Default Value: ""

Custom parameters to be passed to the signing service (uninterpreted).

Data
string

Default Value: ""

Additional data to be included in the async state and mirrored back by the requestor

ExternalHashCalculation

KeyID
string

Default Value: ""

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

KeySecret
string

Default Value: ""

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Read more about configuring authentication in the KeyID topic.

Method

Available options:

ecmDefaultThe default value (0)
ecmDisabledDo not use DC or external signing (1)
ecmGenericGeneric external signing with OnExternalSign event (2)
ecmDCAuthDCAuth signing (3)
ecmDCAuthJSONDCAuth signing in JSON format (4)

PublicKeyAlgorithm
string

Default Value: ""

Provide public key algorithm here if the certificate is not available on the pre-signing stage.

ECCurves
string

Default Value: ""

Defines the elliptic curves to enable.

Extensions
string

Default Value: ""

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
bool

Default Value: False

Whether to force TLS session resumption when the destination address changes.

PreSharedIdentity
string

Default Value: ""

Defines the identity used when the PSK (Pre-Shared Key) key-exchange mechanism is negotiated.

PreSharedKey
string

Default Value: ""

Contains the pre-shared for the PSK (Pre-Shared Key) key-exchange mechanism, encoded with base16.

PreSharedKeyCiphersuite
string

Default Value: ""

Defines the ciphersuite used for PSK (Pre-Shared Key) negotiation.

RenegotiationAttackPreventionMode
RenegotiationAttackPreventionModes

Default Value: 0

Selects renegotiation attack prevention mechanism.

The following options are available:

crapmCompatible0TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict1Renegotiation attack prevention is enabled and enforced.
crapmAuto2Automatically choose whether to enable or disable renegotiation attack prevention.

RevocationCheck
RevocationCheckKinds

Default Value: 1

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.

crcNone0No revocation checking
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2Check all provided CRL endpoints for all chain certificates.
crcAllOCSP3Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP4Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL5At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP6At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP7At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

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.

Config Settings (WebSocketClient 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.

WebSocketClient Config Settings

CacheStreamOutput:   Tells the component whether to cache stream- and file-bound responses in the component.

Set this property to true to enable caching of potentially long responses obtained with GetFile and GetStream methods. If the response is cached, it will be available via OutputBytes and OutputString properties after the request is completed, but may occupy extra memory resources.

ForceNTLMAuth:   Activates and enforces NTLM authentication.

Set this property to True to force NTLM (Windows Integrated) authentication.

IgnoreUnknownTransferEncodings:   All incoming responses with unknown transfer encodings are ignored if this property is true.

All incoming responses with unknown transfer encodings are ignored if this property is true.

MaxRedirections:   The maximum number of HTTP redirects.

Specifies the maximum number of HTTP redirects. Value 0 prevents any redirections, and -1 allows unlimited redirections.

PersistentAuthHeader:   Whether to resend NTLM negotiation on every request.

Specifies whether to resend NTLM negotiation on every request.

RequestCompressionGZip:   Ask server to use GZip compression.

Ask server to use GZip compression.

RequestCompressionLevel:   Ask server to use the specified compression level.

Ask server to use the specified compression level.

SendBufferSize:   Size of send buffer in bytes.

The size of blocks used to send data to the server.

SuppressRedirectionContent:   Whether to suppress the redirection content.

If this property is set to True, the redirection content will be silently suppressed by the component. Otherwise the message containing a redirection code will be processed as usual, the Redirection event will be fired, and the data will be written to OutputString or OutputBytes.

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

Use100Continue:   Whether to use 100-continue for POST and PUT commands.

Set this property to True to use the 100-continue approach for POST and PUT commands. In this approach, prior to sending the request body, the client sends a request message asking the server whether it is willing to accept the request body. The request body is sent only if the server accepts it.

UseCompression:   Whether to use GZip compression.

Use this property to tell the server that it can transfer GZIPped data (if the server supports it).

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:

offNo caching (default)
localLocal caching
globalGlobal caching

Cookies:   Gets or sets local cookies for the component.

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:

fileFile
consoleConsole
systemlogSystem Log (supported for Android only)
debuggerDebugger (supported for VCL for Windows and .Net)

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:

timeCurrent time
levelLevel
packagePackage name
moduleModule name
classClass name
methodMethod name
threadidThread Id
contenttypeContent type

allAll details

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:

exclude-packageExclude a package specified in the value
exclude-moduleExclude a module specified in the value
exclude-classExclude a class specified in the value
exclude-methodExclude a method specified in the value
include-packageInclude a package specified in the value
include-moduleInclude a module specified in the value
include-classInclude a class specified in the value
include-methodInclude a method specified in the value

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

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:

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

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:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

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.

TLSSessionGroup:   Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the components.

TLSSessionLifetime:   Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval:   Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

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.
