AmazonSQS Class

Properties Methods Events Config Settings Errors

The AmazonSQS Class provides an easy interface to Amazon's Simple Queue Service (SQS).

Syntax

AmazonSQS

Remarks

The AmazonSQS Class allows you to access Amazon's Simple Queue Service (SQS). SQS allows you to create globally accessible queues on Amazon's servers. These queues can be used by developers to transfer data between distributed application components, without losing messages or requiring each component to always be available. A brief synopsis follows but please refer to Amazon SQS documentation for details.

You will first need to sign up for the SQS service and obtain the AccessKey and SecretKey from Amazon. Then you can start creating queues in your account using CreateQueue. You can then start adding message's to the queue using CreateMessage and retrieve the same using ListMessages.

There are other methods such as ListQueues, DeleteQueue, DeleteMessage etc. that further enable you to manage your SQS queues.

SmoothMQ is also supported. For compatibility with SmoothMQ, APIRequestFormat must be set to 2. Additionally, it is advisable to set ResolveQueueId to true.

IPWorksMQFirewall

LocalHost Property (AmazonSQS 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();

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.

To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.

Data Type

IPWorksMQCertificate

SSLProvider Property (AmazonSQS Class)

The Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.

Syntax

ANSI (Cross Platform)
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Unicode (Windows)
INT GetSSLProvider();
INT SetSSLProvider(INT iSSLProvider);

Possible Values

SSLP_AUTOMATIC(0), 
SSLP_PLATFORM(1), 
SSLP_INTERNAL(2)

int ipworksmq_amazonsqs_getsslprovider(void* lpObj);
int ipworksmq_amazonsqs_setsslprovider(void* lpObj, int iSSLProvider);

int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Default Value

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.

Additional Notes

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.

Data Type

Integer

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

Data Type

IPWorksMQCertificate

StatusLine Property (AmazonSQS Class)

This property is the first line of the last server response.

Syntax

ANSI (Cross Platform)
char* GetStatusLine();

Unicode (Windows)
LPWSTR GetStatusLine();

char* ipworksmq_amazonsqs_getstatusline(void* lpObj);

QString GetStatusLine();

Default Value

Remarks

This property contains the first line of the last server response. This value can be used for diagnostic purposes. If an HTTP error is returned when calling a method of the class, the error string is the same as the StatusLine property.

The HTTP protocol specifies the structure of the StatusLine as follows: [HTTP version] [Result Code] [Description].

This property is read-only and not available at design time.

Data Type

String

Timeout Property (AmazonSQS Class)

The timeout for the class.

Syntax

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int ipworksmq_amazonsqs_gettimeout(void* lpObj);
int ipworksmq_amazonsqs_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

Default Value

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

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.

Data Type

Integer

UseSSL Property (AmazonSQS Class)

Use SSL when accessing the service.

Syntax

ANSI (Cross Platform)
int GetUseSSL();
int SetUseSSL(int bUseSSL);

Unicode (Windows)
BOOL GetUseSSL();
INT SetUseSSL(BOOL bUseSSL);

int ipworksmq_amazonsqs_getusessl(void* lpObj);
int ipworksmq_amazonsqs_setusessl(void* lpObj, int bUseSSL);

bool GetUseSSL();
int SetUseSSL(bool bUseSSL);

Default Value

TRUE

Remarks

Use this property to specify whether the class should use SSL when connecting to the service.

This property is not available at design time.

Data Type

Boolean

VisibilityTimeout Property (AmazonSQS Class)

The visibility duration for messages in the queue.

Syntax

ANSI (Cross Platform)
int GetVisibilityTimeout();
int SetVisibilityTimeout(int iVisibilityTimeout);

Unicode (Windows)
INT GetVisibilityTimeout();
INT SetVisibilityTimeout(INT iVisibilityTimeout);

int ipworksmq_amazonsqs_getvisibilitytimeout(void* lpObj);
int ipworksmq_amazonsqs_setvisibilitytimeout(void* lpObj, int iVisibilityTimeout);

int GetVisibilityTimeout();
int SetVisibilityTimeout(int iVisibilityTimeout);

Default Value

-1

Remarks

Visibility timeout is used to guard against multiple delivery. Successive calls to ListMessages on a queue will not return any message again until the timeout expires, after which the message may reappear unless deleted with DeleteMessage.

A default visibility timeout is configured when a queue is created using CreateQueue, it can also be altered when a message is added using CreateMessage or when they are retrieved using ListMessages.

The default value for VisibilityTimeout is -1, which notifies the component that you would like to use the default behavior for the current Queue.

Note: Unlike messages received from standard queues, messages received from FIFO queues can only be deleted within their VisibilityTimeout. Attempting to call DeleteMessage for a message received from a FIFO queue after its VisibilityTimeout has expired will cause the server to return an error. Keep this in mind when picking a VisibilityTimeout value to create a FIFO queue and/or retrieve messages with.

Data Type

Integer

AddPermission Method (AmazonSQS Class)

Adds a permission to a queue for a specific account, which allows for sharing access to the queue.

Syntax

ANSI (Cross Platform)
char* AddPermission(const char* lpszQueueId, const char* lpszUserLabel, const char* lpszAmazonAccount, const char* lpszPermissionName);

Unicode (Windows)
LPWSTR AddPermission(LPCWSTR lpszQueueId, LPCWSTR lpszUserLabel, LPCWSTR lpszAmazonAccount, LPCWSTR lpszPermissionName);

char* ipworksmq_amazonsqs_addpermission(void* lpObj, const char* lpszQueueId, const char* lpszUserLabel, const char* lpszAmazonAccount, const char* lpszPermissionName);

QString AddPermission(const QString& qsQueueId, const QString& qsUserLabel, const QString& qsAmazonAccount, const QString& qsPermissionName);

Remarks

This method adds a permission to the queue specified by QueueId for the user account specified by AmazonAccount. UserLabel is the unique identification of the permission you're granting, and is used when deleting the permission via the RemovePermission method. The current list of values you may pass in the PermissionName parameter are listed below:

SendMessage
ReceiveMessage
DeleteMessage
ChangeMessageVisibility
GetQueueAttributes

Note that when you create a queue, you have full control access rights for the queue. Only you (as owner of the queue) can grant or deny permissions to the queue.

AddPermission writes an SQS-generated policy. If you want to write your own policy, use SetQueueAttribute to upload your policy.

This method returns the RequestId contained in the Amazon response.

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.

ChangeMessageVisibility Method (AmazonSQS Class)

Changes the visibility timeout of a message.

Syntax

ANSI (Cross Platform)
char* ChangeMessageVisibility(const char* lpszQueueId, const char* lpszReceiptHandle, int iVisiblityTimeout);

Unicode (Windows)
LPWSTR ChangeMessageVisibility(LPCWSTR lpszQueueId, LPCWSTR lpszReceiptHandle, INT iVisiblityTimeout);

char* ipworksmq_amazonsqs_changemessagevisibility(void* lpObj, const char* lpszQueueId, const char* lpszReceiptHandle, int iVisiblityTimeout);

QString ChangeMessageVisibility(const QString& qsQueueId, const QString& qsReceiptHandle, int iVisiblityTimeout);

Remarks

Changes the visibility of the message specified by ReceiptHandle in the queue specified by QueueId. The maximum allowed timeout value you can set the value to is 12 hours. This means you can't extend the timeout of a message in an existing queue to more than a total visibility timeout of 12 hours.

This method returns the RequestId contained in the Amazon response.

Error Handling (C++)

Config Method (AmazonSQS Class)

Sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworksmq_amazonsqs_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++)

CreateMessage Method (AmazonSQS Class)

Adds a message to a queue.

Syntax

ANSI (Cross Platform)
char* CreateMessage(const char* lpszQueueId, const char* lpszMessage);

Unicode (Windows)
LPWSTR CreateMessage(LPCWSTR lpszQueueId, LPCWSTR lpszMessage);

char* ipworksmq_amazonsqs_createmessage(void* lpObj, const char* lpszQueueId, const char* lpszMessage);

QString CreateMessage(const QString& qsQueueId, const QString& qsMessage);

Remarks

Adds a message to the queue specified. If VisibilityTimeout is specified it is updated for all the messages in the queue.

CreateMessage returns a message id assigned to the message that is added to a queue. This can then be used to ListMessages or DeleteMessage.

Note: When adding a message to a FIFO queue, the MessageGroupId configuration setting must be populated before calling this method.

Error Handling (C++)

CreateQueue Method (AmazonSQS Class)

Creates an SQS queue.

Syntax

ANSI (Cross Platform)
char* CreateQueue(const char* lpszQueueName);

Unicode (Windows)
LPWSTR CreateQueue(LPCWSTR lpszQueueName);

char* ipworksmq_amazonsqs_createqueue(void* lpObj, const char* lpszQueueName);

QString CreateQueue(const QString& qsQueueName);

Remarks

A queue with the specified name is created.

CreateQueue returns a queue id assigned to the queue. This can then be used to CreateMessage or DeleteQueue.

If the QueueName ends with .fifo, the queue will be created as a FIFO queue. Alternatively, if the UseFIFOQueues configuration setting is enabled, the class will always attempt to create FIFO queues, appending .fifo to the given QueueName if necessary (all FIFO queues' names must have that suffix).

Error Handling (C++)

DeleteMessage Method (AmazonSQS Class)

Deletes the message specified.

Syntax

ANSI (Cross Platform)
int DeleteMessage(const char* lpszQueueId, const char* lpszReceiptHandle);

Unicode (Windows)
INT DeleteMessage(LPCWSTR lpszQueueId, LPCWSTR lpszReceiptHandle);

int ipworksmq_amazonsqs_deletemessage(void* lpObj, const char* lpszQueueId, const char* lpszReceiptHandle);

int DeleteMessage(const QString& qsQueueId, const QString& qsReceiptHandle);

Remarks

Deletes the message specified by ReceiptHandle from the queue specified by QueueId.

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.)

DeleteQueue Method (AmazonSQS Class)

Deletes a queue.

Syntax

ANSI (Cross Platform)
int DeleteQueue(const char* lpszQueueId);

Unicode (Windows)
INT DeleteQueue(LPCWSTR lpszQueueId);

int ipworksmq_amazonsqs_deletequeue(void* lpObj, const char* lpszQueueId);

int DeleteQueue(const QString& qsQueueId);

Remarks

Deletes the queue specified by QueueId.

Error Handling (C++)

DoEvents Method (AmazonSQS Class)

This method processes events from the internal message queue.

Syntax

ANSI (Cross Platform)
int DoEvents();

Unicode (Windows)
INT DoEvents();

int ipworksmq_amazonsqs_doevents(void* lpObj);

int DoEvents();

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Error Handling (C++)

GetQueueAttributes Method (AmazonSQS Class)

Returns all attributes of a queue.

Syntax

ANSI (Cross Platform)
char* GetQueueAttributes(const char* lpszQueueId);

Unicode (Windows)
LPWSTR GetQueueAttributes(LPCWSTR lpszQueueId);

char* ipworksmq_amazonsqs_getqueueattributes(void* lpObj, const char* lpszQueueId);

QString GetQueueAttributes(const QString& qsQueueId);

Remarks

This method retrieves all of the attributes of the queue specified by QueueId, and stores them in the Attributes collection. Queues currently have five attributes that may be returned:

ApproximateNumberOfMessages
VisibilityTimeout (for more information, see Visibility Timeout)
CreatedTimestamp
LastModifiedTimestamp
Policy

This method returns the RequestId contained in the Amazon response.

Error Handling (C++)

GetXValue Method (AmazonSQS Class)

Retrieves a valid XPath expression from the HTTP response after calling SendCustomRequest .

Syntax

ANSI (Cross Platform)
char* GetXValue(const char* lpszXPath);

Unicode (Windows)
LPWSTR GetXValue(LPCWSTR lpszXPath);

char* ipworksmq_amazonsqs_getxvalue(void* lpObj, const char* lpszXPath);

QString GetXValue(const QString& qsXPath);

Remarks

This method allows a user to retrieve a valid XPath expression from the HTTP response after calling SendCustomRequest.

Error Handling (C++)

Interrupt Method (AmazonSQS Class)

This method interrupts the current method.

Syntax

ANSI (Cross Platform)
int Interrupt();

Unicode (Windows)
INT Interrupt();

int ipworksmq_amazonsqs_interrupt(void* lpObj);

int Interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

Error Handling (C++)

ListMessages Method (AmazonSQS Class)

Gets messages from the queue.

Syntax

ANSI (Cross Platform)
int ListMessages(const char* lpszQueueId);

Unicode (Windows)
INT ListMessages(LPCWSTR lpszQueueId);

int ipworksmq_amazonsqs_listmessages(void* lpObj, const char* lpszQueueId);

int ListMessages(const QString& qsQueueId);

Remarks

This method retrieves messages from the queue specified by QueueId, and fires a Message event for each message it receives. The messages may also be accessed using the property Messages.

If VisibilityTimeout greater than -1 it is applied to the messages, otherwise the default timeout of the queue used. Only one message is retrieved by default; this behavior may be modified by changing MaxMessages.

Error Handling (C++)

ListQueues Method (AmazonSQS Class)

Lists the queues under the current account.

Syntax

ANSI (Cross Platform)
int ListQueues();

Unicode (Windows)
INT ListQueues();

int ipworksmq_amazonsqs_listqueues(void* lpObj);

void EndTransfer(AmazonSQSEndTransferEventParams *e);

// Or, subclass AmazonSQS and override this emitter function.
virtual int FireEndTransfer(AmazonSQSEndTransferEventParams *e) {...}

Remarks

This event is fired first when the client finishes sending data to the server (in a POST or PUT request) and then when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (AmazonSQS Class)

void SSLServerAuthentication(AmazonSQSSSLServerAuthenticationEventParams *e);

// Or, subclass AmazonSQS and override this emitter function.
virtual int FireSSLServerAuthentication(AmazonSQSSSLServerAuthenticationEventParams *e) {...}

Remarks

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 (AmazonSQS Class)

Fired when secure connection progress messages are available.

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).

StorePassword
char*
Default Value: ""

If the type of certificate store requires a password, this field is used to specify the password needed to open the certificate store.

StoreType
int
Default Value: 0

The type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class will automatically determine the type. This field can take one of the following values:


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: This store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: This store type is only available in Java.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)	The certificate store is the name of a PKCS#7 file containing certificates.
12 (cstP7BBlob)	The certificate store is a string (binary) representing a certificate store in PKCS#7 format.
13 (cstSSHPublicKeyFile)	The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)	The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)	The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)	The certificate store is the name of a file that contains a certificate in XML format.

22 (cstBCFKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: This store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN. Code Example. SSH Authentication with Security Key: `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

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.
O	Organization
OU	Organizational Unit
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

IPWorksMQFirewall (declared in ipworksmq.h)

Constructors

Firewall()

Proxy Type

The proxy the component will connect to.

Syntax

IPWorksMQProxy (declared in ipworksmq.h)

Remarks

When connecting through a proxy, this type is used to specify different properties of the proxy, such as the Server and the AuthScheme.

The following fields are available:

Fields

AuthScheme
int
Default Value: 0

The type of authorization to perform when connecting to the proxy. This is used only when the User and Password fields are set.

AuthScheme should be set to authNone (3) when no authentication is expected.

By default, AuthScheme is authBasic (0), and if the User and Password fields are set, the class will attempt basic authentication.

If AuthScheme is set to authDigest (1), digest authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If AuthScheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this field will clear the values of User and Password.

AutoDetect
int
Default Value: FALSE

Whether to automatically detect and use proxy system settings, if available. The default value is false.

Password
char*
Default Value: ""

A password if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password fields are Base64 encoded and the proxy authentication token will be generated in the form Basic [encoded-user-password].

If AuthScheme is set to Digest Authentication, the User and Password fields are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.

Port
int
Default Value: 80

The Transmission Control Protocol (TCP) port for the proxy Server (default 80). See the description of the Server field for details.

Server
char*
Default Value: ""

If a proxy Server is given, then the HTTP request is sent to the proxy instead of the server otherwise specified.

If the Server field is set to a domain name, a DNS request is initiated. Upon successful termination of the request, the Server field is set to the corresponding address. If the search is not successful, an error is returned.

SSL
int
Default Value: 0

When to use a Secure Sockets Layer (SSL) for the connection to the proxy. The applicable values are as follows:


psAutomatic (0)	Default setting. If the URL is an `https` URL, the class will use the `psTunnel` option. If the URL is an `http` URL, the class will use the `psNever` option.
psAlways (1)	The connection is always SSL-enabled.
psNever (2)	The connection is not SSL-enabled.
psTunnel (3)	The connection is made through a tunneling (HTTP) proxy.

User
char*
Default Value: ""

A username if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password fields are Base64 encoded and the proxy authentication token will be generated in the form Basic [encoded-user-password].

If AuthScheme is set to Digest Authentication, the User and Password fields are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.

IPWorksMQList Type

Syntax

IPWorksMQList<T> (declared in ipworksmq.h)

Remarks

IPWorksMQList 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 AmazonSQS 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 (AmazonSQS 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.

AmazonSQS Config Settings

APIRequestFormat: Changes the API request format.

Possible values are as follows:


0 (default)	Sends GET requests using AWS query protocol.
1	Sends POST requests using AWS query protocol.
2	Sends POST requests using AWS JSON protocol.

APIVersion: Service's API version.

This describes the API version as defined by the service of the current protocol. The default is set to the version that the class was designed around, but may be changed to a different version.

Amazon defines each version as the date it was released. An example is: "2009-07-15".

HTTPMethod: Specifies the HTTP method to use when sending a custom request.

The following methods are supported: GET,PUT,HEAD,POST and DELETE and are only used when SendCustomRequest is called. The default value is "" (empty string) in which case the default HTTP methods are used (more details about the default behavior can be found on the SendCustomRequest page).

MessageAttributeCount: The number of message attributes.

This setting is used to get or set the number of message attributes. This setting is applicable in SQS when calling the CreateMessage and ListMessages methods. This setting is applicable in SNS when calling the PublishMessage method.

MessageAttributeDataType[i]: The data type of the message attribute.

This setting can be used to get or set the data type of the message attribute. This setting is applicable in SQS when calling the CreateMessage and ListMessages methods. This setting is applicable in SNS when calling the PublishMessage method.

Possible values are:

0 (string - default)
1 (number)
2 (binary)

Valid array indices are from 0 to MessageAttributeCount - 1.

MessageAttributeName[i]: The name of the message attribute.

This setting can be used to get or set the message attribute name. This setting is applicable in SQS when calling the CreateMessage and ListMessages methods. This setting is applicable in SNS when calling the PublishMessage method.

Valid array indices are from 0 to MessageAttributeCount - 1.

MessageAttributeValue[i]: The value of the message attribute.

This setting gets or sets the value of the message attribute. This setting is applicable in SQS when calling the CreateMessage and ListMessages methods. This setting is applicable in SNS when calling the PublishMessage method.

Valid array indices are from 0 to MessageAttributeCount - 1.

MessageDeduplicationId: The message deduplication ID for the message being created.

First-In-First-Out (FIFO) queues support deduplication of sent messages. If a message with a particular message deduplication ID is sent successfully, any messages sent with the same message deduplication ID are accepted successfully, but are not delivered during the 5-minute deduplication interval. This only applies when creating message in a FIFO queue, and should be provided for each message sent in the following scenarios:

Messages sent with identical message bodies that Amazon SQS must treat as unique.
Messages sent with identical content but different message attributes that Amazon SQS must treat as unique.
Messages sent with different content (for example, retry counts included in the message body) that Amazon SQS must treat as duplicates.

MessageGroupId: The ID of the message group to which the message belongs.

First-In-First-Out (FIFO) queues support message groups that allow multiple ordered message groups within a single queue. Messages that belong to the same message group are processed in a FIFO manner (however, messages in different message groups might be processed out of order). This only applies when creating message in a FIFO queue and is required to be set.

PurgeQueue: Deletes all messages in a queue specified by the QueueId.

Used to purge all messages from the specified queue. Set this to the QueueId of the queue to be purged.

When you purge a queue, the message deletion process takes up to 60 seconds. All messages sent to the queue before calling PurgeQueue will be deleted; messages sent to the queue while it is being purged may be deleted. While the queue is being purged, messages sent to the queue before PurgeQueue was called may be received, but will be deleted within the next minute.

ResolveQueueId: If set to true (default false), requests that require Queue URL can also be resolved using the Queue ID.

The component will make an extra request invoking the AmazonSQS.GetQueueUrl method and use its response for the request that will require the Queue URL to be resolved.

SignatureVersion: The version of signature used.

The signature version used in the request. The default value is "4".

SignCustomRequest: Tells the component to sign the outgoing request.

By default, this configuration is True, and when SendCustomRequest is called the class will sign the specified request to authenticate with the service. If set to False, the request will be sent as is, without signing.

TransferredData: Returns the entire XML response received from the server.

URL: If set, the default URL will be overridden by this value.

By default, the class uses the service's URL. Setting this config will override this value. This should be only the base URL but not include the Queue name. For example: sqs.Config("URL=https://myregion.custom-sqs-server.com"); sqs.ListMessages("MyQueue");

UseEC2RoleCredentials: If set, authenticate requests with credentials obtained from the specified IAM role attached to the EC2 instance.

When the class is running within an Amazon EC2 instance, this setting can be set to the name of an IAM role in order to automatically authenticate requests as that IAM role using temporary credentials obtained from the EC2 instance itself.

In order for the class to be able to auto-obtain authentication credentials, the EC2 instance must have an "instance profile" with an appropriate IAM role attached to it. Refer to the "Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances" page in the Amazon IAM documentation for more information.

By default, this setting is empty. When populated with an IAM role name, the class will do the following before each request:

Make a request against the EC2 instance to obtain temporary security credentials for the IAM role associated with the current instance profile.
Parse the response, automatically populating the AccessKey and SecretKey properties.
Execute the original request using the temporary security credentials that were acquired.

UseFIFOQueues: Whether queues should always be created as FIFO queues.

This setting specifies whether the class should always attempt to create queues as FIFO queue. By default, it is disabled, and a queue will only be created as a FIFO queue if the QueueName passed to CreateQueue ends with .fifo (this is a required suffix for all FIFO queues).

When enabled, the class will always append the .fifo suffix (if necessary) to the desired QueueName when CreateQueue is called. (Note that queue names can be no longer than 80 characters, including the .fifo suffix.)

HTTP Config Settings

AcceptEncoding: Used to tell the server which types of content encodings the client supports.

When AllowHTTPCompression is True, the class adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The class only supports gzip and deflate decompression algorithms.

AllowHTTPCompression: This property enables HTTP compression for receiving data.

This configuration setting enables HTTP compression for receiving data. When set to True (default), the class will accept compressed data. It then will uncompress the data it has received. The class will handle data compressed by both gzip and deflate compression algorithms.

When True, the class adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

AllowHTTPFallback: Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.

This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the class will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the class fails with an error if the server does not support HTTP/2.

The default value is True.

Append: Whether to append data to LocalFile.

This configuration setting determines whether data will be appended when writing to LocalFile. When set to True, downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is applicable only when LocalFile is set. The default value is False.

Authorization: The Authorization string to be sent to the server.

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

BytesTransferred: Contains the number of bytes transferred in the response data.

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the Transfer event, by BytesTransferred.

ChunkSize: Specifies the chunk size in bytes when using chunked encoding.

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

CompressHTTPRequest: Set to true to compress the body of a PUT or POST request.

If set to True, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

EncodeURL: If set to True the URL will be encoded by the class.

If set to True, the URL passed to the class will be URL encoded. The default value is False.

FollowRedirects: Determines what happens when the server issues a redirect.

This option determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the class fails with an error.

Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the class fails with an error instead.

Following are the valid options:

0 - Never
1 - Always
2 - Same Scheme

GetOn302Redirect: If set to True the class will perform a GET on the new location.

The default value is False. If set to True, the class will perform a GET on the new location. Otherwise, it will use the same HTTP method again.

HTTP2HeadersWithoutIndexing: HTTP2 headers that should not update the dynamic header table with incremental indexing.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

HTTPVersion: The version of HTTP used by the class.

This property specifies the HTTP version used by the class. Possible values are as follows:

"1.0"
"1.1" (default)
"2.0"
"3.0"

When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.

HTTP/2 Notes

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the class will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/3 Notes

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

IfModifiedSince: A date determining the maximum age of the desired document.

If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

KeepAlive: Determines whether the HTTP connection is closed after completion of the request.

If true, the component will not send the Connection: Close header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note: Not all servers support persistent connections. If false, the connection will be closed immediately after the server response is received.

The default value for KeepAlive is false.

KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

LogLevel: The level of detail that is logged.

This configuration setting controls the level of detail that is logged through the Log event. 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 the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

MaxRedirectAttempts: Limits the number of redirects that are followed in a request.

When FollowRedirects is set to any value other than frNever, the class will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

NegotiatedHTTPVersion: The negotiated HTTP version.

This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the class will fall back to using "1.1" automatically. This setting will indicate which version was used.

OtherHeaders: Other headers as determined by the user (optional).

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the class beyond what is provided.

ProxyAuthorization: The authorization string to be sent to the proxy server.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If User and Password are specified, this value is calculated using the algorithm specified by AuthScheme.

ProxyAuthScheme: The authorization scheme to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPassword: A password if authentication is to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPort: Port for the proxy server (default 80).

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyServer: Name or IP address of a proxy server (optional).

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyUser: A user name if authentication is to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

SentHeaders: The full set of headers as sent by the client.

This configuration setting returns the complete set of raw headers as sent by the client.

StatusCode: The status code of the last response from the server.

This configuration setting contains the result code of the last response from the server.

StatusLine: The first line of the last response from the server.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

TransferredData: The contents of the last response from the server.

This configuration setting contains the contents of the last response from the server.

TransferredDataLimit: The maximum number of incoming bytes to be stored by the class.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the class.

TransferredHeaders: The full set of headers as received from the server.

This configuration setting returns the complete set of raw headers as received from the server.

TransferredRequest: The full request as sent by the client.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

UseChunkedEncoding: Enables or Disables HTTP chunked encoding for transfers.

If UseChunkedEncoding is set to True, the class will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the class will not use HTTP-chunked encoding. The default value is False.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

UseIDNs: Whether to encode hostnames to internationalized domain names.

This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001. In the C++ Edition for Windows, the *W version of the class must be used. For instance, DNSW or HTTPW.

UsePlatformHTTPClient: Whether or not to use the platform HTTP client.

When using this configuration setting, if True, the component will use the default HTTP client for the platform (URLConnection in Java, WebRequest in .NET, or CFHTTPMessage in Mac/iOS) instead of the internal HTTP implementation. This is important for environments in which direct access to sockets is limited or not allowed (e.g., in the Google AppEngine).

Note: This setting is applicable only to Mac/iOS editions.

UseProxyAutoConfigURL: Whether to use a Proxy auto-config file when attempting a connection.

This configuration specifies whether the class will attempt to use the Proxy auto-config URL when establishing a connection and AutoDetect is set to True.

When True (default), the class will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

UserAgent: Information about the user agent (browser).

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

TCPClient Config 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 class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect: Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost: Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

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 setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPassword: 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 class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort: The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType: Determines the type of firewall to connect through.

Possible values are as follows:


0	No firewall (default setting).
1	Connect through a tunneling proxy. FirewallPort is set to 80.
2	Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3	Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10	Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser: 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 class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval: 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 acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration 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 macOS.

KeepAliveRetryCount: The number of keep-alive packets to be sent before the remotehost is considered disconnected.

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 acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the number of times that the keep-alive packets will be sent before the remote host is considered disconnected. The system default if this value is not specified here is 9.

Note: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.

KeepAliveTime: 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 Transmission Control Protocol (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.

Linger: 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), 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.

LingerTime: Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost: 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 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).

LocalPort: The port in the local host where the class binds.

This configuration setting 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 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.

MaxLineLength: 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 string.

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.

MaxTransferRate: The transfer rate limit in bytes per second.

This configuration 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.

ProxyExceptionsList: A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration 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:

www.google.com;www.nsoftware.com

TCPKeepAlive: 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.

TcpNoDelay: Whether or not to delay when sending packets.

When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

UseIPv6: Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class 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 as follows:


0	IPv4 only
1	IPv6 only
2	IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets: Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is False, as it is useful only 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 configuration setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir: The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

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.

OpenSSLCAFile: Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

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.

OpenSSLCipherList: A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

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".

OpenSSLPrngSeedData: The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

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.

ReuseSSLSession: Determines if the SSL session is reused.

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.

SSLCACertFilePaths: The paths to CA certificate files on Unix/Linux.

This configuration setting specifies the paths on disk to CA certificate files on Unix/Linux.

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

SSLCACerts: A newline separated list of CA certificates to be included when performing an SSL handshake.

When SSLProvider is set to Internal, this configuration setting specifies one or more CA certificates to be included with the SSLCert property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. 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

... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCipherStrength: The minimum cipher strength used for bulk encryption.

This minimum cipher strength is 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.

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.

SSLClientCACerts: A newline separated list of CA certificates to use during SSL client certificate validation.

This configuration setting is only applicable to server components (e.g., TCPServer) see SSLServerCACerts for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when SSLAuthenticateClients is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

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

d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLEnabledCipherSuites: The cipher suite to be used in an SSL negotiation.

This configuration setting enables the 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 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.

Example values when SSLProvider is set to Platform include the following: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include the following:

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.

SSLEnabledProtocols: Used to enable/disable the supported security protocols.

This configuration setting is used to enable or disable the supported security protocols.

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.

SSLEnableRenegotiation: Whether the renegotiation_info SSL extension is supported.

This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is false by default, but it can be set to true to enable the extension.

This configuration setting is applicable only when SSLProvider is set to Internal.

SSLIncludeCertChain: Whether the entire certificate chain is included in the SSLServerAuthentication event.

This configuration 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.

SSLKeyLogFile: The location of a file where per-session secrets are written for debugging purposes.

This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

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.

SSLNegotiatedCipher: Returns the negotiated cipher suite.

This configuration setting returns the cipher suite negotiated during the SSL handshake.

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]");

SSLNegotiatedCipherStrength: Returns the negotiated cipher suite strength.

This configuration setting returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite: Returns the negotiated cipher suite.

This configuration setting returns the cipher suite negotiated during the SSL handshake represented as a single string.

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

This configuration setting returns the key exchange algorithm negotiated during the SSL handshake.

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake.

SSLNegotiatedVersion: Returns the negotiated protocol version.

This configuration setting returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags: Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions:


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.

SSLServerCACerts: A newline separated list of CA certificates to use during SSL server certificate validation.

This configuration setting is only used by client components (e.g., TCPClient) see SSLClientCACerts for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

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

... Root Cert...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

TLS12SignatureAlgorithms: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This configuration setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

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.

TLS12SupportedGroups: The supported groups for ECC.

This configuration 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 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)

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

This configuration 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 roundtrip 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 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)
"ecdhe_secp521r1"
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096"
"ffdhe_6144"
"ffdhe_8192"

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following:

"ed25519" (default)
"ed448" (default)
"ecdsa_secp256r1_sha256" (default)
"ecdsa_secp384r1_sha384" (default)
"ecdsa_secp521r1_sha512" (default)
"rsa_pkcs1_sha256" (default)
"rsa_pkcs1_sha384" (default)
"rsa_pkcs1_sha512" (default)
"rsa_pss_sha256" (default)
"rsa_pss_sha384" (default)
"rsa_pss_sha512" (default)

The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This configuration setting is applicable only when SSLEnabledProtocols includes TLS 1.3.

TLS13SupportedGroups: The supported groups for (EC)DHE key exchange.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,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:

"ecdhe_x25519" (default)

Socket Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that 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 User Datagram Protocol (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).

InBufferSize: The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

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.

OutBufferSize: 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. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

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.

Trappable Errors (AmazonSQS 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.

AmazonSQS Errors

601	An error returned from Amazon SQS. Please refer to the error message for explanation.
