GlobalDebit ConfigurationThe 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.
GlobalDebit Configuration Settings
Indicates if the POS device is capable of accepting PINs.Required if the point of sale is EMV capable. Valid values are:
Indicates if the POS device is only able to accept chip inserted EMV transactions.Required if the point of sale is EMV capable. Valid values are:
Indicates whether the Point of Sale is EMV enabled.This configuration setting is required for transactions using EMV cards. Submit a value of True for an EMV transaction. Default value is False.
Note: This must be set to True even for swiped or keyed fallback transactions using EMV cards.
|EMVData: The EMV data returned from a Pin Pad after reading an EMV card.This configuration setting takes the entire TLV (tag-length-value) EMV data received from a Pin Pad after reading an EMV card.|
|ResponseEMVData: The response EMV data.This configuration setting contains the EMV Data in TLV (tag-length-value) format. This field will only be populated if an EMV transaction was performed and EMV Data was received in the response.|
The EMV Data Entry Source (DES).This configuration setting indicates how the values for the payment information were obtained.
Valid values are:
|RawRequest: Returns the request sent to the server for debugging purposes.After an operation this setting may be queried to return the request as it was sent to the server. This is useful for debugging purposes.|
|RawResponse: Returns the response received from the server for debugging purposes.After an operation this setting may be queried to return the response as it was received from the server. This is useful for debugging purposes.|
IPPort Configuration Settings
|ConnectionTimeout: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the component will use Timeout for establishing a connection and transmitting/receiving data.|
|FirewallAutoDetect: Tells the component whether or not to automatically detect and use firewall system settings, if available.This is the same as AutoDetect. This setting is provided for use by components that do not directly expose Firewall properties.|
Name or IP address of firewall (optional).If a FirewallHost is given, requested connections will be authenticated through the specified firewall
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
NOTE: This is the same as Host. This setting is provided for use by components that do not directly expose Firewall properties.
If true, the component binds to a SOCKS firewall as a server (IPPort only).This entry is for IPPort only and does not work for other components that descend from IPPort.
If this entry is set, the component acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.
RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.
The connection to the firewall is made by calling the Connect method.
Password to be used if authentication is to be used when connecting through the firewall.If FirewallHost is specified, the FirewallUser and FirewallPassword settings
are used to connect and authenticate to the given firewall. If the authentication fails, the component throws an exception.
NOTE: This is the same as Password. This setting is provided for use by components that do not directly expose Firewall properties.
The TCP port for the FirewallHost;.Note that the FirewallPort is set automatically when FirewallType is set to a valid value.
NOTE: This is the same as Port. This setting is provided for use by components that do not directly expose Firewall properties.
Determines the type of firewall to connect through.The appropriate values are as follows:
NOTE: This is the same as FirewallType. This setting is provided for use by components that do not directly expose Firewall properties.
A user name if authentication is to be used connecting through a firewall.If the FirewallHost is specified, the FirewallUser and FirewallPassword
settings are used to connect and authenticate to the Firewall. If the authentication fails, the component throws an exception.
NOTE: This is the same as User. This setting is provided for use by components that do not directly expose Firewall properties.
The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, TCPKeepAlive will automatically be set to true.
By default the operating system will determine the
time a connection is idle before a TCP keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many
cases a shorter interval is more useful. Set this value to the desired interval in milliseconds.
Note: This value is not applicable in Java.
The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, TCPKeepAlive will automatically be set to true.
A TCP keep-alive packet will be sent after a period of inactivity as
defined by KeepAliveTime. If no acknowledgement is received from the remote host the keep-alive packet
will be re-sent. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds.
This system default if this value is not specified here is 1 second.
Note: This value is not applicable in Java or MAC.
When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True.
In the case that Linger is True (default), there are two scenarios for determining how long the connection will linger. The first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP protocol timeout expires.
In the second scenario, LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the component returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.
|LingerTime: Time in seconds to have the connection linger. LingerTime is the time, in seconds, to leave the socket connection linger. This value is 0 by default, which means it will use the default IP protocol timeout.|
The name of the local host through which connections are initiated or accepted.
The LocalHost setting 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.
If the component 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 multi-homed hosts (machines with more than one IP interface).
The port in the local host where the component binds.
This must be set before a connection is
attempted. It instructs the component to bind to a specific
port (or communication endpoint) in the local machine.
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; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
The maximum amount of data to accumulate when no EOL is found.MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes. The maximum value is 65536 bytes.
|MaxTransferRate: The transfer rate limit in bytes per second.This setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default this is not set and there is no limit.|
A semicolon separated list of hosts and IPs to bypass when using a proxy.This setting optionally specifies a semicolon separated list of hostnames or IP addresses to bypass when a proxy is in use.
When requests are made to hosts specified in this property the proxy will not be used. For instance:
Determines whether or not the keep alive socket option is enabled.If set to true, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically
to maintain the connection. Set KeepAliveTime and KeepAliveInterval to
configure the timing of the keep-alive packets.
Note: This value is not applicable in Java.
Whether to use IPv6.When set to 0 (default), the component will use IPv4 exclusively.
When set to 1, the component will use IPv6 exclusively. To instruct the component to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0.
Possible values are:
|UseNTLMv2: Whether to use NTLM V2.When authenticating with NTLM this setting specifies whether NTLM V2 is used. By default this value is False and NTLM V1 will be used. Set this to True to use NTLM V2.|
|CloseStreamAfterTransfer: If true, the component will close the upload or download stream after the transfer.This setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, set this to False. the default value is True.|
Whether or not to delay when sending packets.
When true, the socket will send all data that is ready to send at once. When
false, the socket will send smaller buffered packets of data at small intervals.
This is known as the Nagle algorithm.
By default, this config is set to false.
SSL Configuration Settings
The paths to CA certificate files when using Mono on Unix/Linux.This setting specifies the paths on disk to CA certificate files when using Mono on Unix/Linux. It
is not applicable in any other circumstances.
The value is formatted as a list of paths separated by semicolons. The component will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server certificates.
The default value is:
Controls whether SSL packets are logged when using the internal security API.When the UseInternalSecurityAPI configuration setting is True, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this setting has no effect if UseInternalSecurityAPI is False.
Determines if the SSL session is reused.
If set to true, the component will reuse the context if and only if the following criteria are met:
The minimum cipher strength used for bulk encryption.
This minimum cipher strength largely dependent on the security modules installed
on the system. If the cipher strength specified is not supported,
an error will be returned when connections are initiated.
Please note that this 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 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 config setting.
Used to enable/disable the supported security protocols.Used to enable/disable the supported security protocols.
Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList setting.
Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.
Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.
Whether the entire certificate chain is included in the SSLServerAuthentication event.This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains
the full certificate chain. By default this value is False and only the leaf certificate will be present
in the Encoded parameter of the SSLServerAuthentication event.
If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.
The name of the security provider to use.
Change this setting to use security providers other than the system default.
Use this setting with caution. Disabling SSL security or pointing to the wrong provider could potentially cause serious security vulnerabilities in your application.
The special value "*" (default) picks the default SSL provider defined in the system.
The special value "Internal" picks the internal SSL implementation. This does not rely on any system libraries. This is equivalent to setting UseInternalSecurityAPI to True.
Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed except to a value of "Internal".
Flags that control certificate verification.The following flags are defined (specified in hexadecimal
notation). They can be or-ed together to exclude multiple
This functionality is currently not available in Java or when the provider is OpenSSL.
A newline separated list of CA certificate to use during SSL client authentication.This setting specifies one or more CA certificates to be included in the request when performing
SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented
when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
The cipher suite to be used in an SSL negotiation.The enabled cipher suites to be used in SSL negotiation.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the component 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.
Example values when UseInternalSecurityAPI is False (default):
obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES");Possible values when UseInternalSecurityAPI is False (default) include:
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_DH_ANON_WITH_AES_128_CBC_SHA");Possible values when UseInternalSecurityAPI is True include:
When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Defines the allowed TLS 1.2 signature algorithms when UseInternalSecurityAPI is True.This setting specifies the allowed server certificate signature algorithms when UseInternalSecurityAPI is
True and SSLEnabledProtocols is set to allow TLS 1.2.
When specified the component will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the component throws an exception.
The format of this value is a comma separated list of hash-signature combinations. For instance:
IPPort.Config("UseInternalSecurityAPI=true"); IPPort.Config("SSLEnabledProtocols=3072"); //TLS 1.2 IPPort.Config("TLS12SignatureAlgorithms=sha1-rsa,sha1-dsa,sha256-rsa,sha256-dsa");The default value for this setting is "sha1-rsa,sha1-dsa,sha224-rsa,sha224-dsa,sha256-rsa,sha256-dsa,sha384-rsa,sha384-dsa,sha512-rsa,sha512-dsa".
In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The supported groups for ECC.This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and UseInternalSecurityAPI is set to True, the values refer to the supported groups for ECC. The following values are supported:
The groups for which to pregenerate key shares.This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange.
The groups specified here will have key share data pregenerated locally before establishing a connection.
This can prevent an additional round trip during the handshake if the group is supported by the server.
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
The supported groups for (EC)DHE key exchange.This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange.
This setting should only be modified if there is a specific reason to do so.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192
The values are ordered from most preferred to least preferred. The following values are supported:
The allowed certificate signature algorithms.This setting holds a comma separated list of allowed signature algorithms. Possible values are:
Socket Configuration Settings
Determines whether timeouts are inactivity timeouts or absolute timeouts.If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds
will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.
Note: This option is not valid for UDP ports.
|FirewallData: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).|
The size in bytes of the incoming queue of the socket.
This is the size of an internal queue in the TCP/IP stack.
You can increase or decrease its size depending on the amount
of data that you will be receiving. Increasing the value of the
InBufferSize setting can provide significant improvements in
performance in some cases.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack.
You can increase or decrease its size depending on the amount
of data that you will be sending. Increasing the value of the
OutBufferSize setting can provide significant improvements in
performance in some cases.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Base Configuration Settings
Tells the component whether or not a message loop is available for processing events.In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.
In some non-GUI applications an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GuiAvailable to false will ensure that the component does not attempt to process external events.
|UseBackgroundThread: Whether threads created by the component are background threads.If set to True, when the component creates a thread the thread's IsBackground property will be explicitly set to True. By default this setting is False.|
Tells the component whether or not to use the system security libraries or an internal implementation.
By default the component will use the system security libraries to perform cryptographic functions.
When set to False calls to unmanaged code will be made. In certain environments this is not desirable.
To use a completely managed security implementation set this setting to True.
Setting this to True tells the component to use the internal implementation
instead of using the system's security API.
Note: This setting is static. The value set is applicable to all components used in the application.
When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.
