An easy-to-use AMQP 1.0 client implementation.
Syntax
AMQP
Remarks
The AMQP class provides an easy-to-use AMQP 1.0 client implementation. The class supports both plaintext and TLS-enabled connections over TCP.
Connecting
AMQP 1.0's transport protocol has three layers: an overarching connection between two containers, the sessions opened on that connection, and the links (between the containers' nodes) attached to those sessions.The class implements all three layers of the AMQP 1.0 transport protocol, so the first step is to initiate the overall connection. Set the ContainerId property and call the ConnectTo method, passing it the server's hostname and port number.
Once connected, the next step is to create at least one session, which can be accomplished by using the CreateSession method. The class allows creating any number of sessions, up to the limit specified by the MaxSessionCount configuration setting.
Connecting and Creating a Session
amqp1.ContainerId = "testClient";
amqp1.ConnectTo("amqp.test-server.com", 5672);
amqp1.CreateSession("TestSession");
After creating a session, the next step is to create one or more links (which are created in the context of a session) so that messages can be sent and/or received. Links are unidirectional, so each one has a sender on one end and a receiver on the other.
The class can function both as a sender node (by opening sender links) and as a receiver node (by opening receiver links). But keep in mind that, since the class is implemented as an AMQP 1.0 client, it must be the one to open links (said another way, the class cannot accept any link requests made by other peers).
As with sessions, the class allows creating any number of links for each session, up to the limit specified by the MaxLinkCountPerSession configuration setting.
Creating Sender Links
To create a sender link, call the CreateSenderLink method, passing it the name of an existing session, a unique name for the link, and (if necessary in your environment) the name of a target for the receiver to use to ensure messages are routed correctly.The LinkReadyToSend event will fire when the newly created sender link is ready to send messages.
Creating a Sender Link
amqp1.OnLinkReadyToSend += (s, e) => {
Console.WriteLine("Link '" + e.LinkName + "' is ready to send messages!");
};
amqp1.CreateSenderLink("TestSession", "TestSenderLink", "TestTarget");
Sending Messages
To send a message, the first step is to set the Message property's fields to the desired values.At minimum, the Value and ValueType fields must be set. All other fields are optional, though specifying a unique value for MessageId is recommended. (If the GenerateMessageId configuration setting is enabled, the class will generate one automatically when the message is sent.)
Once the Message property's fields have be assigned as desired, call the SendMessage method, passing it the name of an existing sender link on which the message should be sent.
The MessageOut event will be fired when the message has been sent (and acknowledged, if Settled was set to false). The MessageOutcome event may also fire, if necessary, once the receiver reports the outcome of the message.
Refer to SendMessage, MessageOut, and MessageOutcome for more information.
Sending a Message
amqp1.OnMessageOut += (s, e) => {
Console.WriteLine("Message with Id '" + e.MessageId + "' has been sent on link '" + e.LinkName + "'.");
};
amqp1.Message.MessageId = "TestMessageId";
amqp1.Message.Value = "Hello, world!";
amqp1.Message.ValueType = AMQPValueTypes.mvtString;
amqp1.SendMessage("TestSenderLink");
The ResetMessage method can be used to reset the Message property's fields to their default values.
Sending Composite AMQP Data
The AMQP 1.0 protocol's data model includes the concept of "composite data". Composite data is comprised of one or more type-value pairs (including data structure types), plus a descriptor that describes what the overall data represents.The class supports sending composite AMQP data in a message through the use of JSON with a well-defined schema. Refer to the SendMessage method's documentation for more information and examples.
Creating Receiver Links
Receiver links can operate in one of two receive modes: automatic, where the class will work to ensure that messages are received as soon as they are available; and retrieve-based, where the class will only "retrieve" a new message when explicitly instructed to.The ReceiveMode property controls which receive mode newly-created receiver links will use; refer to its documentation for more information.
After ensuring that ReceiveMode is set as desired, call CreateReceiverLink, passing it the name of an existing session, a unique name for the link, and (if necessary in your environment) the name of a source for the sender to route the link creation request to.
Creating a Receiver Link
// Creating an automatic receiver link.
amqp1.ReceiveMode = AmqpReceiveModes.rmAutomatic;
amqp1.CreateReceiverLink("TestSession", "TestAutoReceiverLink", "TestSource1");
// Creating a retrieve-based receiver link.
amqp1.ReceiveMode = AmqpReceiveModes.rmRetrieve;
amqp1.CreateReceiverLink("TestSession", "TestRetrieveReceiverLink", "TestSource2");
Receiving Messages
For receiver links created in automatic receive mode (the default), messages are received automatically.For receiver links created in retrieve-based mode, the class will attempt to "retrieve" a message each time the RetrieveMessage method is called (optionally timing out after a time, if RetrieveTimeout is non-zero). When calling RetrieveMessage, pass it the name of a retrieve-based receiver link.
Regardless of whether a messages is received automatically or retrieved, any incoming message will cause the class to fire the MessageIn event and update the ReceivedMessage property's fields.
When the MessageIn event fires, its State event parameter can be used to specify the outcome of the message, which the class will then transmit back to the sender (as well as self-report by firing the MessageOutcome event). Refer to MessageIn for more information.
Receiving a Message
// For automatic receiver links, only the event handler is necessary.
amqp1.OnMessageIn += (s, e) => {
Console.WriteLine("Message with Id '" + e.MessageId + "' has been received on link '" + e.LinkName + "'. Value:");
Console.WriteLine(amqp1.ReceivedMessage.Value);
// The message state is already set to the "Accepted" outcome by default, but we'll set it again
// for the purpose of this example.
e.State = 0; // 0 = Accepted.
};
// For retrieve-based links, it's also necessary to call RetrieveMessage(). It is recommended that the
// RetrieveTimeout property be set to a non-zero value (60 seconds is the default) so that the retrieve
// request will eventually time out if the sender doesn't have any messages available to deliver.
amqp1.RetrieveTimeout = 60;
amqp1.RetrieveMessage("TestRetrieveReceiverLink");

int ipworksiot_amqp_setcontainerid(void* lpObj, const char* lpszContainerId);
QString GetContainerId();
int SetContainerId(QString qsContainerId);
Default Value
""
Remarks
This property specifies the container Id that the class should advertise when it's connecting to the remote host.
In AMQP, the top-level organizational grouping is called a "container", and each container can contain zero or more "nodes", which are the actual entities which send and receive messages over links.
Since this class handles multiple layers of the AMQP transport protocol (the overall connection, the sessions in that connection, and the links attached to those sessions), it must be given a unique container Id.
Note: The container Id cannot be changed while connected.
This property is not available at design time.

Data Type
LocalHost Property (AMQP Class)
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
ANSI (Cross Platform) char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost); Unicode (Windows) LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);
char* ipworksiot_amqp_getlocalhost(void* lpObj);
int ipworksiot_amqp_setlocalhost(void* lpObj, const char* lpszLocalHost);
QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);
Default Value
""
Remarks
This 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.
Data Type
String
LocalPort Property (AMQP Class)
The TCP port in the local host where the class binds.
Syntax
ANSI (Cross Platform) int GetLocalPort();
int SetLocalPort(int iLocalPort); Unicode (Windows) INT GetLocalPort();
INT SetLocalPort(INT iLocalPort);
int ipworksiot_amqp_getlocalport(void* lpObj);
int ipworksiot_amqp_setlocalport(void* lpObj, int iLocalPort);
int GetLocalPort();
int SetLocalPort(int iLocalPort);
Default Value
0
Remarks
This property must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.
Setting this property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the LocalPort property after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this property when a connection is active will generate an error.
This property is useful when trying to connect to services that require a trusted port on the client side.
Data Type

ReadyToSend Property (AMQP Class)
Indicates whether the class is ready to send data.
Syntax
ANSI (Cross Platform) int GetReadyToSend(); Unicode (Windows) BOOL GetReadyToSend();
int ipworksiot_amqp_getreadytosend(void* lpObj);
bool GetReadyToSend();
Default Value
FALSE
Remarks
This property indicates that the underlying TCP/IP subsystem is ready to accept data. This is True after connecting to the remote host, and will become False if a call to SendMessage fails due to a WOULDBLOCK condition.
Once data can be sent again, the ReadyToSend event will fire and this property will be True.
If a WOULDBLOCK error occurs while sending a message the class will automatically complete the transmission when sending is possible. No action needs to be taken to re-send the message. ReadyToSend will fire after the class completes any partially sent messages.
This property is read-only and not available at design time.

Data Type
ReceiveMode Property (AMQP Class)
Controls what mode new receiver links are created with.
Syntax
ANSI (Cross Platform) int GetReceiveMode();
int SetReceiveMode(int iReceiveMode); Unicode (Windows) INT GetReceiveMode();
INT SetReceiveMode(INT iReceiveMode);
Possible Values
RM_AUTOMATIC(0),
RM_RETRIEVE(1)
int ipworksiot_amqp_getreceivemode(void* lpObj);
int ipworksiot_amqp_setreceivemode(void* lpObj, int iReceiveMode);
int GetReceiveMode();
int SetReceiveMode(int iReceiveMode);
Default Value
0
Remarks
This property controls which receive mode newly created receiver links should use to receive messages from the sender. Valid values are:
- rmAutomatic (0 - default)
- rmRetrieve (1)
Receiving Messages Automatically
A receiver link operating in rmAutomatic (0) mode strives to ensure that the sender always has sufficient credit so that messages are received as soon as they are available, thus simulating a "subscription-based"/"push-based" messaging model.In this mode, receiver links will be created with the amount of credit, and the credit threshold, specified by the DefaultCredit and DefaultCreditThreshold configuration settings. Anytime the link's credit reaches the credit threshold, the class will automatically set it back to its initial value.
Retrieving Messages On-Demand
A receiver link operating in rmRetrieve (1) mode requires the RetrieveMessage method to be called in order for a message to be received, thus simulating a "polling"/"pull-based" messaging model.In this mode, receiver links will be created with no credit (regardless of what DefaultCredit is set to). When RetrieveMessage is called, the class will supply the sender with a single credit and then block until a message is received (if the RetrieveTimeout property is set to zero).
If RetrieveTimeout is non-zero, the class will only block for the specified number of seconds; once that time expires, it will instruct the sender to consume the credit. If the sender chooses to consume the credit by incrementing the value of the LinkDeliveryCount field rather than by sending a message, then the class will throw an error indicating a timeout.
Refer to RetrieveMessage and RetrieveTimeout for more information.

Data Type
Integer
RemoteHost Property (AMQP Class)
This property includes the address of the remote host. Domain names are resolved to IP addresses.
Syntax
ANSI (Cross Platform) char* GetRemoteHost();
int SetRemoteHost(const char* lpszRemoteHost); Unicode (Windows) LPWSTR GetRemoteHost();
INT SetRemoteHost(LPCWSTR lpszRemoteHost);
char* ipworksiot_amqp_getremotehost(void* lpObj);
int ipworksiot_amqp_setremotehost(void* lpObj, const char* lpszRemoteHost);
QString GetRemoteHost();
int SetRemoteHost(QString qsRemoteHost);
Default Value
""
Remarks
This property specifies the IP address (IP number in dotted internet format) or the domain name of the remote host. It is set before a connection is attempted and cannot be changed once a connection is established.
If this property is set to a domain name, a DNS request is initiated, and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.
If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.
Example. Connecting:
TCPClientControl.RemoteHost = "MyHostNameOrIP"
TCPClientControl.RemotePort = 777
TCPClientControl.Connected = true
Data Type
String
RemotePort Property (AMQP Class)

Syntax
ANSI (Cross Platform) int GetRemotePort();
int SetRemotePort(int iRemotePort); Unicode (Windows) INT GetRemotePort();
INT SetRemotePort(INT iRemotePort);
int ipworksiot_amqp_getremoteport(void* lpObj);
int ipworksiot_amqp_setremoteport(void* lpObj, int iRemotePort);
int GetRemotePort();
int SetRemotePort(int iRemotePort);
Default Value
5672
Remarks
This property specifies a service port on the remote host to connect to.
A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.
This property is not available at design time.
Data Type
Integer
RetrieveTimeout Property (AMQP Class)
How long the class should wait for a message to be received after RetrieveMessage is called.
Syntax

int SetSSLAcceptServerCertEncoded(QByteArray qbaSSLAcceptServerCertEncoded);
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.

Data Type
SSLEnabled Property (AMQP Class)
This property indicates whether Transport Layer Security/Secure Sockets Layer (TLS/SSL) is enabled.
Syntax
ANSI (Cross Platform) int GetSSLEnabled();
int SetSSLEnabled(int bSSLEnabled); Unicode (Windows) BOOL GetSSLEnabled();
INT SetSSLEnabled(BOOL bSSLEnabled);
int ipworksiot_amqp_getsslenabled(void* lpObj);
int ipworksiot_amqp_setsslenabled(void* lpObj, int bSSLEnabled);
bool GetSSLEnabled();
int SetSSLEnabled(bool bSSLEnabled);
Default Value
FALSE
Remarks
This property specifies whether TLS/SSL is enabled in the class. When False (default), the class operates in plaintext mode. When True, TLS/SSL is enabled.
TLS/SSL may also be enabled by setting SSLStartMode. Setting SSLStartMode will automatically update this property value.
If the default port (5672) is selected when SSLEnabled is set to true, the port will automatically be changed to the default port for AMQP with SSL (5671). Likewise, if port 5671 is selected when SSLEnabled is set to false, the port will automatically be changed to the default port. If the port has been set to any value other than the default values, it will remain the same when the value of SSLEnabled changes.
This property is not available at design time.
Data Type

int ipworksiot_amqp_getsslprovider(void* lpObj);
int ipworksiot_amqp_setsslprovider(void* lpObj, int iSSLProvider);
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are as follows:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.
When Automatic is selected, on Windows, the class will use the platform implementation. On Linux/macOS, the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used on all platforms.

Remarks
This property contains the server certificate for the last established connection.
SSLServerCert is reset every time a new connection is attempted.
This property is read-only.
Data Type
Timeout Property (AMQP Class)
This property includes the timeout for the class.
Syntax
ANSI (Cross Platform) int GetTimeout();
int SetTimeout(int iTimeout); Unicode (Windows) INT GetTimeout();
INT SetTimeout(INT iTimeout);
int ipworksiot_amqp_gettimeout(void* lpObj);
int ipworksiot_amqp_settimeout(void* lpObj, int iTimeout);
int GetTimeout();
int SetTimeout(int iTimeout);
Default Value
60
Remarks
If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.
If Timeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.
The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.
If Timeout expires, and the operation is not yet complete, the class fails with an error.
Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.

Syntax
ANSI (Cross Platform) int CloseLink(const char* lpszName); Unicode (Windows) INT CloseLink(LPCWSTR lpszName);
int ipworksiot_amqp_closelink(void* lpObj, const char* lpszName);
int CloseLink(const QString& qsName);
Remarks
This method closes the link named Name and removes it from the Links properties. If no link with the given Name exists, an error will be thrown.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
CloseSession Method (AMQP Class)

Syntax
ANSI (Cross Platform) int CloseSession(const char* lpszName); Unicode (Windows) INT CloseSession(LPCWSTR lpszName);
int ipworksiot_amqp_closesession(void* lpObj, const char* lpszName);
int CloseSession(const QString& qsName);
Remarks

Any links open on the specified session when this method is called will be automatically closed and removed from the Links properties.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Config Method (AMQP Class)
Sets or retrieves a configuration setting.
Syntax
ANSI (Cross Platform) char* Config(const char* lpszConfigurationString); Unicode (Windows) LPWSTR Config(LPCWSTR lpszConfigurationString);
char* ipworksiot_amqp_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
Connect Method (AMQP Class)

int ipworksiot_amqp_connectto(void* lpObj, const char* lpszHost, int iPort);
int ConnectTo(const QString& qsHost, int iPort);
Remarks
This method connects to the remote host specified by the Host and Port parameters. For instance:
component.ConnectTo("MyHostNameOrIP", 777)
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CreateReceiverLink Method (AMQP Class)
Creates a new receiver link with the given name on the specified session.
Syntax
ANSI (Cross Platform) int CreateReceiverLink(const char* lpszSessionName, const char* lpszName, const char* lpszSource); Unicode (Windows) INT CreateReceiverLink(LPCWSTR lpszSessionName, LPCWSTR lpszName, LPCWSTR lpszSource);
int ipworksiot_amqp_createreceiverlink(void* lpObj, const char* lpszSessionName, const char* lpszName, const char* lpszSource);
int CreateReceiverLink(const QString& qsSessionName, const QString& qsName, const QString& qsSource);
Remarks
This method creates a new receiver link with the given Name on the session specified by SessionName and adds it to the Links properties. If a link (sender or receiver) with the given Name already exists, or if no session with the given SessionName exists, an error will be thrown.
Source may be set to specify the address of the node at the remote host which should act as the sender. This may not be necessary in all environments, in which case an empty string will suffice.
Receiver links can operate in one of two receive modes: automatic, where the class will work to ensure that messages are received as soon as they are available; and retrieve-based, where the class will only "retrieve" a new message when explicitly instructed to.
The ReceiveMode property controls which receive mode newly-created receiver links will use; refer to its documentation for more information.
AMQP 1.0's transport protocol has three layers: an overarching connection between two containers, the sessions opened on that connection, and the links (between the containers' nodes) attached to those sessions.
amqp.ReceiveMode = AmqpReceiveModes.rmRetrieve;
amqp.CreateReceiverLink("SessionID", "ReceiverLinkName", "SomeTarget");
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
CreateSenderLink Method (AMQP Class)
Creates a new sender link with the given name on the specified session.
Syntax
ANSI (Cross Platform) int CreateSenderLink(const char* lpszSessionName, const char* lpszName, const char* lpszTarget); Unicode (Windows) INT CreateSenderLink(LPCWSTR lpszSessionName, LPCWSTR lpszName, LPCWSTR lpszTarget);
int ipworksiot_amqp_createsenderlink(void* lpObj, const char* lpszSessionName, const char* lpszName, const char* lpszTarget);
int CreateSenderLink(const QString& qsSessionName, const QString& qsName, const QString& qsTarget);
Remarks
This method creates a new sender link with the given Name on the session specified by SessionName and adds it to the Links properties. If a link (sender or receiver) with the given Name already exists, or if no session with the given SessionName exists, an error will be thrown.
Target may be set to specify the address of the node at the remote host which should act as the receiver. This may not be necessary in all environments, in which case an empty string will suffice.
The LinkReadyToSend event will fire when a newly-created sender link is ready to send.
Sender links are created using the Mixed settle mode by default, letting the value of the Settled field control whether each message is settled (the default) or unsettled when it is sent. The DefaultSenderSettleMode configuration setting can be used to control the settle mode that new sender links are created with. Refer to SendMessage for more information on message settlement in general.
AMQP 1.0's transport protocol has three layers: an overarching connection between two containers, the sessions opened on that connection, and the links (between the containers' nodes) attached to those sessions.

Syntax
ANSI (Cross Platform) int Disconnect(); Unicode (Windows) INT Disconnect();
int ipworksiot_amqp_disconnect(void* lpObj);
int Disconnect();
Remarks
This method disconnects from the remote host. Calling this method is equivalent to setting the Connected property to False.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
DoEvents Method (AMQP Class)
This method processes events from the internal message queue.
Syntax
ANSI (Cross Platform) int DoEvents(); Unicode (Windows) INT DoEvents();

Syntax
ANSI (Cross Platform) int Interrupt(); Unicode (Windows) INT Interrupt();
int ipworksiot_amqp_interrupt(void* lpObj);
int Interrupt();
Remarks
This method interrupts the current action. If you use SendFile to upload a file, the class will run synchronously until the upload is completed. This method will allow you to stop the file from uploading without disconnecting from the host.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

int ResetMessage();
Remarks
This method resets the Message property.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
RetrieveMessage Method (AMQP Class)
Retrieves a single message over the specified receiver link.
Syntax
ANSI (Cross Platform) int RetrieveMessage(const char* lpszLinkName); Unicode (Windows) INT RetrieveMessage(LPCWSTR lpszLinkName);
int ipworksiot_amqp_retrievemessage(void* lpObj, const char* lpszLinkName);
int RetrieveMessage(const QString& qsLinkName);
Remarks
When RetrieveMessage is called, the class will supply the sender with a single credit and then block until a message is received (if the RetrieveTimeout property is set to zero).
If RetrieveTimeout is non-zero, the class will only block for the specified number of seconds; once that time expires, it will instruct the sender to consume the credit. If the sender chooses to consume the credit by incrementing the value of the LinkDeliveryCount field rather than by sending a message, then the class will throw an error indicating a timeout.
LinkName specifies the receiver link which should retrieve a message; if there is no such link, if the specified link is not a receiver link, or if the specified receiver link is not operating in rmSyncGet (1) mode, an error is thrown.
Refer to ReceiveMode and RetrieveTimeout for more information.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
SendMessage Method (AMQP Class)
Sends a message on the specified link.
Syntax
ANSI (Cross Platform) int SendMessage(const char* lpszLinkName); Unicode (Windows) INT SendMessage(LPCWSTR lpszLinkName);
int ipworksiot_amqp_sendmessage(void* lpObj, const char* lpszLinkName);
int SendMessage(const QString& qsLinkName);
Remarks
This method sends a message on the link specified by LinkName.
The Message property holds an AMQPMessage object whose fields are used to construct the message to send. At minimum, specify a Value and a ValueType.
amqp.Message.ValueType = AMQPValueTypes.mvtString;
amqp.Message.Value = "Hello World!";
amqp.SendMessage("SenderLinkName");
Message Settlement
AMQP provides the ability to negotiate delivery guarantees through the system of "message settlement". When a link is created, both the sender and the receiver negotiate a settle mode (one for each role) to use. Senders will operate in one of these modes:- Settled - All messages will be sent in a settled state.
- Unsettled - All messages will be sent in an unsettled state.
- Mixed - Messages may be sent either settled or unsettled.
- First - Incoming messages will be settled immediately (and the sender will be notified that the message has been received, if the message was not already settled when sent).
- Second - Incoming messages will be settled after the sender has settled them (and the sender will be notified when a message has been received, if the message was not already settled when sent).
Together, the sender's and receiver's settle modes can form the following delivery guarantees:
Sender's Settle Mode | Receiver's Settle Mode | Effective Delivery Guarantee |
Settled | (Any) | At most once |
Unsettled | First | At least once |
Unsettled | Second | Exactly once |
It is important to note that the message settlement system has a big caveat: Whichever party opens the link can only request that the other end use a specific settle mode. For example, if the class opens a sender link, it has control over the sender settle mode it will use, but it can only request that the remote host use a specific receiver settle mode; so if the class requests that the receiver use Second, the receiver can instead choose to use First (if, e.g., it doesn't support Second).
The class currently only ever requests (and itself only supports) the First receiver settle mode since no other AMQP implementations appear to support the Second receiver settle mode at this time.
The class requests (and uses) the Mixed sender settle mode by default, but supports all of the sender settle modes (the default can be changed using the DefaultSenderSettleMode configuration setting). Sender links created with the Mixed sender use the value of the Settled field to determine whether to send messages as settled or unsettled.
Sending Composite Data
The AMQP 1.0 protocol's data model includes the concept of "composite data". Composite data is comprised of one or more type-value pairs (including data structure types), plus a descriptor that describes what the overall data represents.Composite Data JSON Schema
The class uses JSON with a well-defined schema to represent composite data. The composite data JSON schema consists almost entirely of "type-value" objects, which hold an AMQP typename and a value. The syntax for a type-value object is:
{ "type": "typename", "value": value }
The following table provides a complete list of valid typenames, and describes how the associated values should be represented:
Typename | Description | Value Format |
null | Null | null |
boolean | Boolean | true or false |
ubyte | Unsigned byte | 0 to 255 |
ushort | Unsigned short | 0 to 65535 |
uint | Unsigned integer | 0 to 4294967295 |
ulong | Unsigned long | 0 to 18446744073709551615 |
byte | Byte | -128 to 127 |
short | Short | -32768 to 32767 |
int | Integer | -2147483648 to 2147483647 |
long | Long | -9223372036854775808 to 9223372036854775807 |
float | Float | [IEEE 754 32-bit floating point number] |
double | Double | [IEEE 754 64-bit floating point number] |
decimal | Decimal | Hex-encoded byte string like "0A1B2C3D" |
char | Char | "c" |
timestamp | Timestamp | [Number of milliseconds since the Unix epoch (January 1, 1970 00:00:00 UTC)] |
uuid | UUID | Hex-encoded UUID string like "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" (hyphens optional, case-insensitive) |
binary | Binary data | Hex-encoded byte string like "0A1B2C3D" |
string | String | "UTF-8 string (correctly escaped for JSON)" |
symbol | Symbolic value | "ASCII string" |
array | AMQP array | JSON array with zero or more type-value objects of the same type |
list | AMQP list | JSON array with zero or more type-value objects |
map | AMQP map | JSON array with even number of type-value objects representing keys and values; no duplicate keys allowed |
Arrays, Lists, and Maps
The AMQP data model defines three data structure types: array, list, and map. In the composite data JSON schema, their value is always a JSON array that contains zero or more type-value objects. Data structure types may be nested arbitrarily to any depth.
Note that the array and map data structures each have restrictions on their content:
- The elements in an array must all be of the same type (e.g., their typenames must match).
- The elements in a map represent keys (odd-numbered elements) and values (even-numbered elements). There must be an even number of elements (or none), and the values of the "key" elements must be unique.
{ "type": "map", "value": [ { "type": "symbol", "value": "key1" }, { "type": "string", "value": "value1" }, { "type": "symbol", "value": "key2" }, { "type": "int", "value": 100 } ] }
Described Types
As noted above, AMQP's data model includes the idea of "described types", which is simply a normal AMQP type annotated by a descriptor. The descriptor defines what the data it is associated with represents as a whole.
In the composite data JSON schema, a described type object is just a normal type-value object with an extra "descriptor" property on it (and the "descriptor" property's value is itself a normal type-value object). The syntax for a described type object is:
{ "descriptor": { "type": "typename", "value": value }, "type": "typename", "value": value }
Described type objects can be used anywhere that normal type-value objects can be, except as the value of the "descriptor" property for another described type object, which must be a normal type-value object.
Note that, according to the AMQP specification, the type of the descriptor itself ulong or symbol, but the class does not enforce this.
Abbreviated Value Syntax
For brevity, it is possible to abbreviate both normal type-value objects and described type objects when their value type is null, boolean, or string.
For normal type-value objects, instead of using the standard syntax (e.g., { "type": "string", "value": "Hello, world!" }), just use the raw value itself (e.g., "Hello, world!"). Keep in mind that the abbreviated value must still be valid JSON; notably, strings must still be surrounded by quotes (e.g., "value", not value).
The abbreviated syntax for a described type object is a bit different; the "descriptor" property still needs to be associated with the value using a JSON object. To abbreviate a described type object, just exclude the "type" property, like so:
{ "descriptor": { "type": "typename", "value": value }, "value": value }
The abbreviated value syntax can be used anywhere that an unabbreviated type-value object or described type object would normally be used.
The class defaults to using the abbreviated syntax when returning composite data JSON. This can be configured using the SimplifiedJSONFormat configuration setting.
Composite Data JSON Example
{ "descriptor": { "type": "symbol", "value": "nsoftware:compositeDataExample" }, "type": "list", "value": [ "Shorthand string value", null, true, { "type": "uuid", "value": "12345678-0000-1000-8000-00805F9B34FB" }, { "type": "array", "value": [ { "type": "uint", "value": 23 }, { "type": "uint", "value": 52 }, { "type": "uint", "value": 153325 } ] }, { "type": "map", "value": [ { "type": "symbol", "value": "name" }, "Freezer temperature", { "type": "symbol", "value": "unit" }, "Fahrenheit", { "type": "symbol", "value": "value" }, { "type": "int", "value": -2 } ] }, { "descriptor": { "type": "symbol", "value": "nsoftware:utf8Bytes" }, "type": "binary", "value": "48656C6C6F2C20776F726C6421" } ] }
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Connected Event (AMQP Class)
Fired immediately after a connection completes (or fails).
Syntax
ANSI (Cross Platform) virtual int FireConnected(AMQPConnectedEventParams *e);
typedef struct {
int StatusCode;
const char *Description; int reserved; } AMQPConnectedEventParams;
Unicode (Windows) virtual INT FireConnected(AMQPConnectedEventParams *e);
typedef struct {
INT StatusCode;
LPCWSTR Description; INT reserved; } AMQPConnectedEventParams;
#define EID_AMQP_CONNECTED 1 virtual INT IPWORKSIOT_CALL FireConnected(INT &iStatusCode, LPSTR &lpszDescription);
class AMQPConnectedEventParams { public: int StatusCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Connected(AMQPConnectedEventParams *e);
// Or, subclass AMQP and override this emitter function. virtual int FireConnected(AMQPConnectedEventParams *e) {...}
Remarks
If the connection is made normally, StatusCode is 0 and Description is "OK".
If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.
Please refer to the Error Codes section for more information.
ConnectionStatus Event (AMQP Class)
Fired to indicate changes in the connection state.
Syntax
ANSI (Cross Platform) virtual int FireConnectionStatus(AMQPConnectionStatusEventParams *e);

Store
char*
Default Value: "MY"
The name of the certificate store for the client certificate.
The StoreType field denotes the type of the certificate store specified by Store. If the store is password-protected, specify the password in StorePassword.
Store is used in conjunction with the Subject field to specify client certificates. If Store has a value, and Subject or Encoded is set, a search for a certificate is initiated. Please see the Subject field for details.
Designations of certificate stores are platform dependent.
The following designations are the most common User and Machine certificate stores in Windows:
MY | A certificate store holding personal certificates with their associated private keys. |
CA | Certifying authority certificates. |
ROOT | Root certificates. |
When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

Default Value: ""
The certificate's version number. The possible values are the strings "V1", "V2", and "V3".
Subject
char*
Default Value: ""
The subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the field is set to the full subject of the matching certificate.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.
The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:
Field | Meaning |
CN | Common Name. This is commonly a hostname like www.server.com. |

L | Locality |
S | State |
C | Country |
E | Email Address |
If a field value contains a comma, it must be quoted.
Encoded
char*
Default Value: ""
The certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.
When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.
Constructors
Certificate()
Creates a instance whose properties can be set. This is useful for use with when generating new certificates.
Certificate(const char* lpEncoded, int lenEncoded)
Parses Encoded as an X.509 public key.
Certificate(int iStoreType, const char* lpStore, int lenStore, const char* lpszStorePassword, const char* lpszSubject)
StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array 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 . 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.
Firewall Type
The firewall the component will connect through.
Syntax
IPWorksIoTFirewall (declared in ipworksiot.h)
Remarks
When connecting through a firewall, this type is used to specify different properties of the firewall, such as the firewall Host and the FirewallType.
Fields
AutoDetect
int
Default Value: FALSE
Whether to automatically detect and use firewall system settings, if available.
FirewallType
int
Default Value: 0

IPWorksIoTList Type
Syntax
IPWorksIoTList<T> (declared in ipworksiot.h)
Remarks
IPWorksIoTList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the AMQP class.
Methods | |
GetCount |
This method returns the current size of the collection.
int GetCount() {}
|
SetCount |
This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection.
int SetCount(int count) {}
|
Get |
This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified.
T* Get(int index) {}
|
Set |
This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class.
T* Set(int index, T* value) {}

Config Settings (AMQP Class)
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.AMQP Config Settings

Note: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if 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 class returns control immediately, the system could hold system resources until all pending data are 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 (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
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.
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.

Note: This value is not applicable in Java.
By default, this configuration setting is set to False.
0 | IPv4 only |
1 | IPv6 only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
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 configuration setting has no effect if SSLProvider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
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.
The value is formatted as a list of paths separated by semicolons. The class 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 or client certificates.
The default value is as follows:
/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ...

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:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ...

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
TLS1.1 | 768 (Hex 300) (Default - Client) |
TLS1 | 192 (Hex C0) (Default - Client) |
SSL3 | 48 (Hex 30) |
SSL2 | 12 (Hex 0C) |
Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.
SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:
By default when TLS 1.3 is enabled, the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.
If set to 1 (Platform provider), please be aware of the following notes:
- The platform provider is available only on Windows 11/Windows Server 2022 and up.
- SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
- If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This configuration setting is applicable only when SSLProvider is set to Internal.
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.
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.
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

0x00000001 | Ignore time validity status of certificate. |
0x00000002 | Ignore time validity status of CTL. |
0x00000004 | Ignore non-nested certificate times. |
0x00000010 | Allow unknown certificate authority. |
0x00000020 | Ignore wrong certificate usage. |
0x00000100 | Ignore unknown certificate revocation status. |
0x00000200 | Ignore unknown CTL signer revocation status. |
0x00000400 | Ignore unknown certificate authority revocation status. |
0x00000800 | Ignore unknown root revocation status. |
0x00008000 | Allow test root certificate. |
0x00004000 | Trust test root certificate. |
0x80000000 | Ignore non-matching CN (certificate CN non-matching server name). |
This functionality is currently not available when the provider is OpenSSL.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
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 fails with an error.
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)
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 configuration setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.
In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.
On Linux, the C++ edition requires installation of the FIPS-enabled OpenSSL library. The OpenSSL FIPS provider version must be at least 3.0.0. For additional information and instructions regarding the installation and activation of the FIPS-enabled OpenSSL library, please refer to the following link: https://github.com/openssl/openssl/blob/master/README-FIPS.md
To ensure the class utilizes the FIPS-enabled OpenSSL library, the obfuscated source code should first be compiled with OpenSSL enabled, as described in the Supported Platforms section. Additionally, the FIPS module should be enabled and active. If the obfuscated source code is not compiled as mentioned, or the FIPS module is inactive, the class will throw an appropriate error assuming FIPS mode is enabled.
FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.
For more details, please see the FIPS 140-2 Compliance article.
Note: This setting is applicable only on Windows.
Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.
Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.
On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.
To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
Trappable Errors (AMQP Class)
Error Handling (C++)
Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
