DTLSClient Module
Properties Methods Events Config Settings Errors
The DTLSClient module provides client-side functionality for secure UDP communication utilizing the Datagram Transport Layer Security (DTLS) protocol.
Syntax
IPWorksDTLS.DTLSClient
Remarks
The DTLSClient class functions as a client that facilitates in connecting to DTLS servers and offers a convenient means of transmitting and receiving datagrams over the established, secure connection.
Connecting to a Server
First, the RemoteHost and RemotePort must be set to the address and port of the target DTLS server. The Timeout property can be used to specify a timeout when connecting to the server. To initiate the connection, call Connect.
After doing so, the handshake process will begin. Relevant handshake details will be reported by the SSLStatus event. Initially, the server will present its certificate to the client. The certificate can be evaluated within the SSLServerAuthentication event. By default, the class will provide a recommendation of whether to accept or reject the certificate, and reasoning behind the recommendation. Regardless, the certificate can be manually accepted (or rejected) within this event.
In some cases, the server requires the client to present a certificate as well. In this case, a valid certificate will need to be specified via the SSLCert property.
Once the connection is complete (or fails), the Connected event will fire. Note that this event will fire if a connection succeeds or fails. If successful, the event will fire with a StatusCode of 0. If this value is non-zero, it indicates the connection was unsuccessful. The Description parameter will contain relevant details. Upon successful connection, the Connected property will be set to True. This process may look like the following:
dtlsclient.OnConnected += (o, e) => {
if (e.StatusCode == 0) {
Console.WriteLine("Connection successful!");
} else {
Console.WriteLine("Connection failed.");
Console.WriteLine("Error code: " + e.StatusCode);
Console.WriteLine("Error description: " + e.Description);
}
};
dtlsclient.OnSSLServerAuthentication += (o, e) => {
if (e.Accept) return;
Console.Write("Server provided the following certificate:\nIssuer: " + e.CertIssuer + "\nSubject: " + e.CertSubject + "\n");
Console.Write("The following problems have been determined for this certificate: " + e.Status + "\n");
Console.Write("Would you like to accept anyways? [y/n] ");
if (Console.Read() == 'y') e.Accept = true;
};
dtlsclient.RemoteHost = "remote_ip";
dtlsclient.RemotePort = 1234;
dtlsclient.Timeout = 30;
// if client authentication is applicable
dtlsclient.SSLCert = new Certificate("/path/to/cert.pfx", CertStoreTypes.cstPFXFile, "cert_password", "cert_subject");
dtlsclient.Connect();
Sending and Receiving Data
Once a successful connection is established, the class can send data to the server via SendText or SendBytes.
The class will also be able to receive data from the server via the DataIn event. Note that this event is non-reentrant, and it is recommended to offload time-consuming operations to ensure the best performance.
If required, the PauseData method can be called, disabling the reception of incoming data from the server. Data reception can later be enabled via the ProcessData method. Note that if this reception is disabled, the server may continue sending data, which will remain unprocessed by the class. In this case, the underlying socket buffer may be filled. This can result in possible data loss originating from the server. Please use these methods with caution.
The complete process may look like the following:
dtlsclient.OnSSLServerAuthentication += (o, e) => {
e.Accept = true;
};
dtlsclient.OnDataIn += (o, e) => {
Console.WriteLine("Packet received from server.");
Console.WriteLine("Datagram: " + e.Datagram);
}
dtlsclient.RemoteHost = "remote_ip";
dtlsclient.RemotePort = 1234;
dtlsclient.Connect();
dtlsclient.SendText("Hello World!");
while (true) {
dtlsclient.DoEvents();
}
Disconnecting from a Server
Once the connection to the server is broken, the Disconnected event will fire. The disconnection can be performed by calling Disconnect, or performed by the server.
In the case a connection ends and an error is encountered, the StatusCode and Description parameters will contain relevant details regarding the error. For example:
dtlsclient.OnDisconnected += (o, e) => {
if (e.StatusCode == 0) {
Console.WriteLine("Connection ended.");
} else {
Console.WriteLine("Connection ended.");
Console.WriteLine("Error code: " + e.StatusCode);
Console.WriteLine("Error description: " + e.Description);
}
};
dtlsclient.RemoteHost = "remote_ip";
dtlsclient.RemotePort = 1234;
dtlsclient.Connect();
...
...
...
dtlsclient.Disconnect();
Additional Information
To support KeepAlive functionality, it is important to note that DoEvents must be called regularly in both console and form-based applications. This is to ensure the class sends keep-alive (or Heartbeat) packets to the server in a timely manner.
In form-based applications, this does not apply if KeepAlive is False.

AcceptData Property (DTLSClient Module)
This property indicates whether data reception is currently enabled.
Syntax
public var acceptData: Bool { get {...} }
@property (nonatomic,readonly,assign,getter=acceptData) BOOL acceptData; - (BOOL)acceptData;
Default Value
True
Remarks
This property indicates whether data reception is currently enabled. When , data reception is disabled and the DataIn event will not fire. Use the PauseData and ProcessData methods to pause and resume data reception.
This property is read-only.
Connected Property (DTLSClient Module)
This property indicates whether the module is connected.
Syntax
public var connected: Bool { get {...} }
@property (nonatomic,readonly,assign,getter=connected) BOOL connected; - (BOOL)connected;
Default Value
False
Remarks
This property indicates whether the class is connected to the remote host. Use the Connect and Disconnect methods to manage the connection.
This property is read-only.
KeepAlive Property (DTLSClient Module)
When True, keep-alive functionality is enabled via the DTLS Heartbeat Extension.
Syntax
public var keepAlive: Bool { get {...} set {...} }
@property (nonatomic,readwrite,assign,getter=keepAlive,setter=setKeepAlive:) BOOL keepAlive; - (BOOL)keepAlive; - (void)setKeepAlive :(BOOL)newKeepAlive;
Default Value
False
Remarks
This property enables keep-alive functionality for the established connection via the DTLS Heartbeat Extension (RFC 6520). Enabling this option can prevent a long connection from timing out in case of inactivity.
Note: For this functionality to work as intended, DoEvents must be called frequently in both console and form-based applications (e.g., using a loop or timer).
Additionally, DTLS server implementations are not required to support Heartbeats.
LocalHost Property (DTLSClient Module)
This property includes the name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
public var localHost: String { get {...} set {...} }
@property (nonatomic,readwrite,assign,getter=localHost,setter=setLocalHost:) NSString* localHost; - (NSString*)localHost; - (void)setLocalHost :(NSString*)newLocalHost;
Default Value
""
Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.
If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Note: LocalHost is not persistent. You must always set it in code, and never in the property window.
LocalPort Property (DTLSClient Module)
This property includes the User Datagram Protocol (UDP) port in the local host where UDP binds.
Syntax
public var localPort: Int32 { get {...} set {...} }
@property (nonatomic,readwrite,assign,getter=localPort,setter=setLocalPort:) int localPort; - (int)localPort; - (void)setLocalPort :(int)newLocalPort;
Default Value
0
Remarks
The LocalPort property must be set before UDP is activated (Active is set to True). This instructs the class to bind to a specific port (or communication endpoint) in the local machine.
Setting it to 0 (default) enables the Transmission Control Protocol (TCP)/IP stack to choose a port at random. The chosen port will be shown by the LocalPort property after the connection is established.
LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.
The LocalPort property is useful when trying to connect to services that require a trusted port on the client side.
RemoteHost Property (DTLSClient Module)
This property includes the address of the remote host. Domain names are resolved to IP addresses.
Syntax
public var remoteHost: String { get {...} set {...} }
@property (nonatomic,readwrite,assign,getter=remoteHost,setter=setRemoteHost:) NSString* remoteHost; - (NSString*)remoteHost; - (void)setRemoteHost :(NSString*)newRemoteHost;
Default Value
""
Remarks
The RemoteHost property specifies the IP address (IP number in dotted internet format) or domain name of the remote host.
If RemoteHost is set to 255.255.255.255, the class broadcasts data on the local subnet.
If the RemoteHost property is set to a domain name, a DNS request is initiated, and upon successful termination of the request, the RemoteHost property is set to the corresponding address. If the search is not successful, an error is returned.
If UseConnection is set to True, the RemoteHost must be set before the class is activated (Active is set to True).
RemotePort Property (DTLSClient Module)
This property specifies the User Datagram Protocol (UDP) port in the remote host.
Syntax
public var remotePort: Int32 { get {...} set {...} }
@property (nonatomic,readwrite,assign,getter=remotePort,setter=setRemotePort:) int remotePort; - (int)remotePort; - (void)setRemotePort :(int)newRemotePort;
Default Value
0
Remarks
The RemotePort is the UDP port on the RemoteHost to send UDP datagrams to.
A valid port number (a value between 1 and 65535) is required.
If UseConnection is set to True, the RemotePort must be set before the class is activated (Active is set to True).
SSLAcceptServerCert Property (DTLSClient Module)
This property instructs the module to unconditionally accept the server certificate that matches the supplied certificate.
Syntax
public var sslAcceptServerCert: Certificate { get {...} set {...} }
@property (nonatomic,readonly,assign,getter=SSLAcceptServerCertEffectiveDate) NSString* SSLAcceptServerCertEffectiveDate; - (NSString*)SSLAcceptServerCertEffectiveDate; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertExpirationDate) NSString* SSLAcceptServerCertExpirationDate; - (NSString*)SSLAcceptServerCertExpirationDate; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertExtendedKeyUsage) NSString* SSLAcceptServerCertExtendedKeyUsage; - (NSString*)SSLAcceptServerCertExtendedKeyUsage; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertFingerprint) NSString* SSLAcceptServerCertFingerprint; - (NSString*)SSLAcceptServerCertFingerprint; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertFingerprintSHA1) NSString* SSLAcceptServerCertFingerprintSHA1;

- (int)SSLAcceptServerCertStoreType; - (void)setSSLAcceptServerCertStoreType :(int)newSSLAcceptServerCertStoreType; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertSubjectAltNames) NSString* SSLAcceptServerCertSubjectAltNames; - (NSString*)SSLAcceptServerCertSubjectAltNames; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertThumbprintMD5) NSString* SSLAcceptServerCertThumbprintMD5; - (NSString*)SSLAcceptServerCertThumbprintMD5; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertThumbprintSHA1) NSString* SSLAcceptServerCertThumbprintSHA1; - (NSString*)SSLAcceptServerCertThumbprintSHA1; @property (nonatomic,readonly,assign,getter=SSLAcceptServerCertThumbprintSHA256) NSString* SSLAcceptServerCertThumbprintSHA256;

- (NSString*)SSLAcceptServerCertEncoded; - (void)setSSLAcceptServerCertEncoded :(NSString*)newSSLAcceptServerCertEncoded; @property (nonatomic,readwrite,assign,getter=SSLAcceptServerCertEncodedB,setter=setSSLAcceptServerCertEncodedB:) NSData* SSLAcceptServerCertEncodedB; - (NSData*)SSLAcceptServerCertEncodedB; - (void)setSSLAcceptServerCertEncodedB :(NSData*)newSSLAcceptServerCertEncoded;
Default Value
60
Remarks
If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.
You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.
Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.
SSLCert Property (DTLSClient Module)
This property includes the certificate to be used during Secure Sockets Layer (SSL) negotiation.

dtlsclient.onSSLServerAuthentication += (o, e) => {
e.Accept = true;
};
dtlsclient.RemotePort = 8765;
dtlsclient.RemoteHost = "HostNameOrIPAddress";
dtlsclient.Connect();
dtlsclient.SendText("Hello!");
To send binary data, use the SendBytes method instead.
Connected Event (DTLSClient Module)
This event is fired immediately after a connection completes (or fails).
Syntax
- (void)onConnected:(NSString*)address :(int)port :(int)statusCode :(NSString*)description;
Remarks
This event is fired immediately after a connection completes (or fails).
If the connection is made normally, StatusCode is 0 and Description is "OK".
If the connection is broken for any other reason, StatusCode will be non-zero, and the Description parameter will contain a description of this code.
DataIn Event (DTLSClient Module)
This event is fired when data are received.
Syntax

The DataIn event is fired every time a new datagram is received.
Datagram contains the packet as sent by the remote host.
SourceAddress contains the IP number (Internet address) of the remote host, and SourcePort contains the port from which the packet originated.
Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
Disconnected Event (DTLSClient Module)
This event is fired when a connection is closed.
Syntax
- (void)onDisconnected:(NSString*)address :(int)port :(int)statusCode :(NSString*)description;
Remarks
This event is fired when a connection is closed.
If the connection is broken normally, StatusCode is 0 and Description is "OK".
If the connection is broken for any other reason, StatusCode will be non-zero, and the Description parameter will contain a description of this code.

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the level of message. Possible values are as follows:
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data are logged. |
| 3 (Debug) | Debug data are logged. |
The value 1 (Info) logs basic information, including users logging in and out, files transferred, and directories listed.
The value 2 (Verbose) includes logs from the PITrail event as well as basic information about data transfer channels.
The value 3 (Debug) logs additional debug information, such as extended socket connection and data transfer information.
Message is the log entry.
LogType identifies the type of log entry. Possible values are as follows:
- "Info"
- "Error"
- "Verbose"

- (void)onSSLServerAuthentication:(NSString*)sourceAddress :(int)sourcePort :(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)accept;
Remarks
This event is fired after the server presents its certificate to the client.
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (DTLSClient Module)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.
public init(storeType: , store: , storePassword: , subject: )
CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a string (binary- or Base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject .

The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.
Config Settings (DTLSClient Module)
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.DTLSClient Config Settings
The class will send a HeartbeatRequest message after a specified period of inactivity, defined by KeepAliveTime. This value specifies the interval at which the class sends successive HeartbeatRequest messages, assuming no response is received from the remote host (HeartbeatResponse). By default, this value is 2 seconds and will only apply if KeepAlive is true.
| 1 | peer_allowed_to_send (default) |
| 2 | peer_not_allowed_to_send |
When set to 2 (peer_not_allowed_to_send), the class will only be capable of sending HeartbeatRequests.
Note, if KeepAlive is false, Heartbeat functionality will be disabled. The class will not be capable of sending or handling HeartbeatRequest messages.
If the connection is inactive for the specified time, the class will send a HeartbeatRequest message to the remote host. If no response is received, the class will continue sending Heartbeats every KeepAliveInterval seconds. By default, this value is 60 seconds and will only apply if KeepAlive is true.
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data are logged. |
| 3 (Debug) | Debug data are logged. |
UDP Config Settings
The default value for this setting is False.
Note: This setting is available only in Windows.
The default value is .
Note: This setting is available only in Windows.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.
Note: This setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later.
Note: This setting uses the qWAVE API and is available only on Windows Vista and Windows Server 2008 or above.
Note: QOSTrafficType must be set before setting Active to True.
The default value for this setting is False.
The default value for this setting is False.
Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time a SSL packet is sent or received.
If set to True, the class will reuse the context if and only if the following criteria are met:
- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the class is the same.

When set to 0 (default), the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
When set to 0 (default), the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
Note: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList configuration setting.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons. For example:
obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=TLS_DHE_DSS_WITH_AES_128_CBC_SHA");
obj.config("SSLEnabledCipherSuites=TLS_DHE_DSS_WITH_AES_128_CBC_SHA;TLS_ECDH_RSA_WITH_AES_128_CBC_SHA");

The default value is 3072. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:
| TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
This configuration setting is applicable only when SSLProvider is set to Internal.
When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.
Note: This configuration setting is applicable only when SSLProvider is set to Internal.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the class .
The format of this value is a comma-separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.
To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
