SNMPTCPMgr Component
Properties Methods Events Config Settings Errors
The SNMPTCPMgr component is used to implement TCP-based SNMP Management Applications.
Syntax
TipnSNMPTCPMgr
Remarks
The SNMPTCPMgr component implements a TCP-based standard SNMP Manager as specified in the SNMP RFCs. The component supports SNMP v1, v2c, and v3.
The component provides both encoding/decoding and transport capabilities, making the task of developing a custom SNMP manager as simple as setting a few key properties and handling a few events. SNMP data, such as for instance SNMP object id-s (OID-s) are exchanged as text strings, thus further simplifying the task of handling them.
The component is activated/deactivated by calling the Activate or Deactivate method. These methods enable or disable sending and receiving. The activation status can be found in the Active property.
Messages are received through events such as Response, Trap, or InformRequest. SNMP Traps are received through the Trap event.
Messages are sent to other agents or managers by using component's methods such as SendGetRequest, SendGetNextRequest, SendGetBulkRequest, SendSetRequest, and SendInformRequest.
SNMP OIDs, types, and values are provided in the Objects collection of SNMP objects for both sent and received packets.
SNMPv3 USM security is enabled by setting properties such as User, AuthenticationPassword, and EncryptionPassword and calling the Discover method to bind to a particular agent (RemoteEngineId). Upon successful discovery, received packets are checked for integrity (authentication) and timeliness. Note that the discovery step is optional, and may be avoided if the values for RemoteEngineId, RemoteEngineBoots, and RemoteEngineTime are known in advance and provided to the component through the respective properties.
By default, the component operates synchronously (except for the Discover method), sending a request and waiting until the corresponding response has been received. This behavior may be overridden by setting Timeout to 0, in which case the component returns control immediately after a send, and responses are received exclusively through the Response event.

ErrorDescription Property (SNMPTCPMgr Component)
Description of the status code for the last SNMP packet received by the component.
Syntax
__property String ErrorDescription = { read=FErrorDescription };
Default Value
"0"
Remarks
Please refer to the ErrorStatus property for more information.
This property is read-only and not available at design time.
Data Type
String
ErrorIndex Property (SNMPTCPMgr Component)
Index of the first variable (object) that caused an error from the last SNMP response.
Syntax
__property int ErrorIndex = { read=FErrorIndex };
Default Value
0
Remarks
This property is used in conjunction with the ErrorStatus property, and refers to the object that caused the error reported in the last SNMP response. This value is parsed directly from the SNMP response, which will be a one-based value, so a value of i here maps to index i-1 in the Objects collection.
The ErrorIndex property has no meaning when the ErrorStatus property is 0 (no error).
This property is read-only and not available at design time.
Data Type
Integer
ErrorStatus Property (SNMPTCPMgr Component)
Status code for the last SNMP packet received by the component.
Syntax
__property int ErrorStatus = { read=FErrorStatus };
Default Value
0
Remarks
This property is used in conjunction with the ErrorIndex property, which denotes the index of the variable in error. The ErrorDescription property provides a textual description of the error.
The following is a list of valid SNMP status code values:
0 (noError) | No error. |

Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).
The default value is 0 (no error).
This property is read-only and not available at design time.
Data Type
Integer
LocalEngineId Property (SNMPTCPMgr Component)
The Engine Id of the SNMP Manager.
Syntax
__property String LocalEngineId = { read=FLocalEngineId, write=FSetLocalEngineId }; __property DynamicArray<Byte> LocalEngineIdB = { read=FLocalEngineIdB, write=FSetLocalEngineIdB };
Default Value
""
Remarks
This property is only used for SNMPv3 packets (when SNMPVersion is 3).
Data Type
Byte Array
LocalHost Property (SNMPTCPMgr Component)
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
__property String LocalHost = { read=FLocalHost, write=FSetLocalHost };
Default Value
""
Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.
If the component is connected, the LocalHost 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 multi-homed 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 (SNMPTCPMgr Component)
The port in the local host where the SNMP Manager is bound to.
Syntax
__property int LocalPort = { read=FLocalPort, write=FSetLocalPort };
Default Value
0
Remarks
The LocalPort property must be set before the component is activated (Active is set to True). It instructs the component to bind to a specific port (or communication endpoint) in the local machine. The default port is 0 (random port). If you would like to receive traps, set LocalPort to 162 (standard trap port). However, it is recommended that the SNMPTrapMgr component be used for listening to traps, because SNMPMgr is limited to receiving SNMPv3 traps from a single agent only. SNMPTrapMgr does not have this limitation.
LocalPort cannot be changed once the component is Active. Any attempt to set the LocalPort property when the component is Active will generate an error.
Note: on macOS and iOS, root permissions are required to set LocalPort to any value below 1024.
Data Type
Integer
ObjCount Property (SNMPTCPMgr Component)
The number of records in the Obj arrays.
Syntax
__property int ObjCount = { read=FObjCount, write=FSetObjCount };

The component also supports the following artificial object values used to designate error conditions:
otNoSuchObject (128) | No such object error. |
otNoSuchInstance (129) | No such instance error. |
otEndOfMibView (130) | End of MIB View error. |
The ObjIndex parameter specifies the index of the item in the array. The size of the array is controlled by the ObjCount property.

The corresponding object type and value (if any) are specified by the ObjectType and ObjValue properties.
Example
SNMPControl.ObjCount = 1
SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0"
The ObjIndex parameter specifies the index of the item in the array. The size of the array is controlled by the ObjCount property.

The value of RemoteEngineTime is provided as what is expected to be the current value of the remote engine clock based on a cached time differential between the remote engine clock and the local engine time obtained during the discovery process (see Discover).
This property is used in conjunction with RemoteEngineBoots. Please refer to the RemoteEngineBoots property and the Discover method for more information.
Data Type
Integer
RemoteHost Property (SNMPTCPMgr Component)
The address of the remote host. Domain names are resolved to IP addresses.
Syntax
__property String RemoteHost = { read=FRemoteHost, write=FSetRemoteHost };
Default Value

When SSLCertEncoded is set, a search is initiated in the current SSLCertStore for the private key of the certificate. If the key is found, SSLCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLCertSubject is set to an empty string.
This property is not available at design time.
Data Type
Byte Array
SSLCertStore Property (SNMPTCPMgr Component)
This is the name of the certificate store for the client certificate.
Syntax
__property String SSLCertStore = { read=FSSLCertStore, write=FSetSSLCertStore }; __property DynamicArray<Byte> SSLCertStoreB = { read=FSSLCertStoreB, write=FSetSSLCertStoreB };
Default Value
"MY"
Remarks
This is the name of the certificate store for the client certificate.
The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.
SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property 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 PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).
Data Type
Byte Array

Default Value
cstUser
Remarks
This is the type of certificate store for this certificate.
The component supports both public and private keys in a variety of formats. When the cstAuto value is used, the component will automatically determine the type. This property 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. |

Syntax
__property String SSLCertSubject = { read=FSSLCertSubject, write=FSetSSLCertSubject };
Default Value
""
Remarks
This is 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.

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.
Data Type

SSLEnabled Property (SNMPTCPMgr Component)
Whether TLS/SSL is enabled.
Syntax
__property bool SSLEnabled = { read=FSSLEnabled, write=FSetSSLEnabled };
Default Value
False
Remarks
This setting specifies whether TLS/SSL is enabled in the component. When False (default) the component operates in plaintext mode. When True TLS/SSL is enabled.
Note: SSL is not currently supported in this product. This setting is reserved for future user.
This property is not available at design time.
Data Type
Boolean
SSLServerCertEncoded Property (SNMPTCPMgr Component)
This is the certificate (PEM/Base64 encoded).
Syntax
__property String SSLServerCertEncoded = { read=FSSLServerCertEncoded }; __property DynamicArray<Byte> SSLServerCertEncodedB = { read=FSSLServerCertEncodedB };
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.
When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.
This property is read-only and not available at design time.
Data Type
Byte Array
StoreWalkObjects Property (SNMPTCPMgr Component)
Tells the component whether or not to store returned objects.
Syntax
__property bool StoreWalkObjects = { read=FStoreWalkObjects, write=FSetStoreWalkObjects };
Default Value
True
Remarks
When a Walk is performed, this property tells the component whether or not to store the objects that are returned by the server in the Objects collection. If the data is accumulated through the events, and not desired to be saved by the component, set this property to false.
Data Type
Boolean
Timeout Property (SNMPTCPMgr Component)
A timeout for the component.
Syntax
__property int Timeout = { read=FTimeout, write=FSetTimeout };
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 component will wait for the operation to complete before returning control. The component will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.
The component 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 component raises an exception.
Please note that by default, all timeouts are inactivity timeouts, i.e. 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
User Property (SNMPTCPMgr Component)
The user name used for SNMPv3 authentication.
Syntax
__property String User = { read=FUser, write=FSetUser };
Default Value
""
Remarks
If authentication is desired, this property must be set before the component attempts to connect to an SNMPv3 Agent.
Data Type
String
WalkLimit Property (SNMPTCPMgr Component)
The limit of oid's returned in a walk.
Syntax
__property int WalkLimit = { read=FWalkLimit, write=FSetWalkLimit };
Default Value
0
Remarks
This property specifies the limit of how many oid's are to be traversed during an SNMP Walk. If set to 0, the component will traverse all oid's in the specified table that are lexographically greater than the value of the specified table oid.
Data Type
Integer
Activate Method (SNMPTCPMgr Component)
Activates the component.
Syntax
void __fastcall Activate();
Remarks
This method activates the component and will allow it to send or receive data.
The component will be automatically activated if it is not already and you attempt to perform an operation which requires the component to be active.
Note: Use the Active property to check whether the component is active.
Config Method (SNMPTCPMgr Component)
Sets or retrieves a configuration setting.
Syntax
String __fastcall Config(String ConfigurationString);
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Deactivate Method (SNMPTCPMgr Component)
Deactivates the component.
Syntax
void __fastcall Deactivate();
Remarks
This method deactivates the component and will prohibit it from sending and receiving data.
Note: Use the Active property to check whether the component is active.
Discover Method (SNMPTCPMgr Component)
Performs SNMPv3 discovery.
Syntax
void __fastcall Discover();
Remarks
When the method is called an SNMPv3 engine discovery request is sent to RemoteHost.
If an AuthenticationPassword is provided, the engine id discovery request is followed by an engine time discovery request, as required by the SNMPv3 User Security Model (USM). In this case Timeout must be set to a non-zero value before calling Discover and the component will wait until a response is received from RemoteHost.
The DiscoveryResponse event is fired upon receipt of a valid discovery response and the values of RemoteEngineId, RemoteEngineBoots, and RemoteEngineTime will then be updated with the received Engine Id, Time, and Boots.
DoEvents Method (SNMPTCPMgr Component)
Processes events from the internal message queue.
Syntax
void __fastcall DoEvents();
Remarks
When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.
HashPasswords Method (SNMPTCPMgr Component)
Hashes all passwords in the cache.
Syntax
void __fastcall HashPasswords();
Remarks
Forces computation of all passwords hashes in the cache. Used together with the HashPassword event to enable implementations of external password hash storage.
Interrupt Method (SNMPTCPMgr Component)
Interrupt the current method.
Syntax
void __fastcall Interrupt();
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
Reset Method (SNMPTCPMgr Component)
Clears the object arrays.
Syntax
void __fastcall Reset();
Remarks
Clears the object arrays, and sets the trap and error properties to their default values. This is useful for reinitializing all the properties that are used to create outgoing packets before building a new packet.
Note: SNMPVersion will be reset to snmpverV2c (2).
SendGetBulkRequest Method (SNMPTCPMgr Component)
Send a GetBulkRequest packet.
Syntax
void __fastcall SendGetBulkRequest(int NonRepeaters, int MaxRepetitions);
Remarks
Sends a GetBulkRequest packet. This is only available for SNMP versions 2 and 3.
NonRepeaters specifies the number of variables for which a single lexicographic successor is to be returned.
MaxRepetitions specifies the number of lexicographic successors to be returned for variables other than those in the NonRepeaters list.
The object identifiers, types, and values for the request are taken from the Objects collection.
A GetBulkRequest is very similar to a GetNextRequest, the difference is that Getbulk performs a continuous GetNext operation based on the MaxRepitions value. The NonRepeaters value will determine the number of Objects for which a simple GetNext operation should be performed. For the remaining variables, a continuous GetNext operation is performed based on the MaxRepitions value.
So if you send a request containing X objects, the agent will perform N simple GetNext operations and M continuous GetNext operations X - N times. With X being the number of objects received, N being the number of NonRepeaters, and M being the number of MaxRepitions. Thus the SNMPMgr is expecting to receive N + M x (X - N) objects, assuming that each object has M successors.
Example (Sending a GetBulk Request)
SNMPControl.RemoteHost = "MyAgent"
SNMPControl.ObjCount = 2
SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0"
SNMPControl.objId(1) = "1.3.6.1.2.1.1.3.0"
SNMPControl.SendGetBulkRequest(1,4)
The code sample above will send a GetBulkRequest with 1 non repeater, and a maxrepetitions of 4. Since there is only 1 non repeater, only one ObjID will "not repeat" and will only return one successor. The rest of the ObjID's (in this case, only 1) will return 4 successors. This particular example will return the following ObjID's:
1 | 1.3.6.1.2.1.1.2.0 |
2 | 1.3.6.1.2.1.1.4.0 |
3 | 1.3.6.1.2.1.1.5.0 |
4 | 1.3.6.1.2.1.1.6.0 |
5 | 1.3.6.1.2.1.1.7.0 |
SendGetNextRequest Method (SNMPTCPMgr Component)
Send GetNextRequest packet.
Syntax
void __fastcall SendGetNextRequest();
Remarks
Sends a GetNextRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection.
Example (Sending a GetNext Request)
SNMPControl.ObjCount = 2
SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0"
SNMPControl.SendGetNextRequest()
The agent will respond with the "next" (relative to the ObjID(s) you specify) OID in the table.
SendGetRequest Method (SNMPTCPMgr Component)
Send GetRequest packet.
Syntax
void __fastcall SendGetRequest();
Remarks
Sends a GetRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection.
Example (Sending a GetRequest)
SNMPControl.RemoteHost = "MyAgent"
SNMPControl.ObjCount = 2
SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0"
SNMPControl.ObjId(1) = "1.3.6.1.2.1.1.2.0"
SNMPControl.SendGetRequest()
SendInformRequest Method (SNMPTCPMgr Component)
Send an InformRequest packet.
Syntax
void __fastcall SendInformRequest();
Remarks
Sends an InformRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection.
SendSetRequest Method (SNMPTCPMgr Component)
Send Set Request packet.
Syntax
void __fastcall SendSetRequest();
Remarks
Sends a SetRequest packet. The object identifiers, types, and values for the request are taken from the Objects collection.
Example (Sending a SetRequest)
SNMPControl.RemoteHost = "MyAgent"
SNMPControl.ObjCount = 1
SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0"
SNMPControl.ObjValue(0) = "New Value"
SNMPControl.ObjType(0) = otOctetString
SNMPControl.SendSetRequest()
Value Method (SNMPTCPMgr Component)
Returns the value corresponding to an OID.
Syntax
String __fastcall Value(String OID);
Remarks
If the OID does not exist in the Objects collection, a trappable error is generated.
Please refer to the SNMPObject type for more information.
Walk Method (SNMPTCPMgr Component)
Does an SNMP walk starting with the specified oid.
Syntax
void __fastcall Walk(String TableOid);
Remarks
A walk will traverse all OIDs in the TableOid that are lexographically greater than the value of the TableOid.
The results of the walk may be obtained through the Response events. During the event, the current returned object will exist inside of the Objects collection. If StoreWalkObjects is set to true, the Objects collection will contain all returned objects when the Walk completes.
Use the WalkLimit property to regulate how many objects the walk will traverse in the table.
NOTE: The collection of objects is cleared before the walk begins.
BadPacket Event (SNMPTCPMgr Component)
Fired for erroneous and/or malformed messages.
Syntax
typedef struct { String Packet; DynamicArray<Byte> PacketB; String SourceAddress; int SourcePort; int ErrorCode; String ErrorDescription; bool Report; } TipnSNMPTCPMgrBadPacketEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrBadPacketEvent)(System::TObject* Sender, TipnSNMPTCPMgrBadPacketEventParams *e); __property TipnSNMPTCPMgrBadPacketEvent OnBadPacket = { read=FOnBadPacket, write=FOnBadPacket };
Remarks
The full message is provided in the Packet parameter.
The BadPacket event is also fired when authentication fails for received packets due to a bad password or other reasons.
If the Report parameter is set to True, an unauthenticated error report will be sent to the client, otherwise the packet will be silently ignored.
Connected Event (SNMPTCPMgr Component)
Fired immediately after a connection completes (or fails).
Syntax
typedef struct { String RemoteAddress; int RemotePort; int StatusCode; String Description; } TipnSNMPTCPMgrConnectedEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrConnectedEvent)(System::TObject* Sender, TipnSNMPTCPMgrConnectedEventParams *e); __property TipnSNMPTCPMgrConnectedEvent OnConnected = { read=FOnConnected, write=FOnConnected };
Remarks
This event fires after a connection completes or fails.
StatusCode is the value returned by the system TCP/IP stack. This will be 0 if the connection was successful.
Description contains a human readable description of the status. This will be "OK" if the connection was successful.
RemoteAddress is the IP address of the remote host.
RemotePort is the port on the remote host.
ConnectionStatus Event (SNMPTCPMgr Component)
This event is fired to indicate changes in the connection state.
Syntax
typedef struct { String ConnectionEvent; int StatusCode; String Description; } TipnSNMPTCPMgrConnectionStatusEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrConnectionStatusEvent)(System::TObject* Sender, TipnSNMPTCPMgrConnectionStatusEventParams *e); __property TipnSNMPTCPMgrConnectionStatusEvent OnConnectionStatus = { read=FOnConnectionStatus, write=FOnConnectionStatus };
Remarks

Disconnected Event (SNMPTCPMgr Component)
Fired when a connection is closed.
Syntax
typedef struct { String RemoteAddress; int RemotePort; int StatusCode; String Description; } TipnSNMPTCPMgrDisconnectedEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrDisconnectedEvent)(System::TObject* Sender, TipnSNMPTCPMgrDisconnectedEventParams *e); __property TipnSNMPTCPMgrDisconnectedEvent OnDisconnected = { read=FOnDisconnected, write=FOnDisconnected };
Remarks
This event fires after a connection is broken.
StatusCode is the value returned by the system TCP/IP stack. This will be 0 if the connection was broken normally.
Description contains a human readable description of the status. This will be "OK" if the connection was broken normally.
RemoteAddress is the IP address of the remote host.
RemotePort is the port on the remote host.
DiscoveryRequest Event (SNMPTCPMgr Component)
Fired when an SNMPv3 discovery packet is received.
Syntax
typedef struct { String EngineId; DynamicArray<Byte> EngineIdB; int EngineBoots; int EngineTime; String User; int SecurityLevel; String SourceAddress; int SourcePort; bool Respond; } TipnSNMPTCPMgrDiscoveryRequestEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrDiscoveryRequestEvent)(System::TObject* Sender, TipnSNMPTCPMgrDiscoveryRequestEventParams *e); __property TipnSNMPTCPMgrDiscoveryRequestEvent OnDiscoveryRequest = { read=FOnDiscoveryRequest, write=FOnDiscoveryRequest };
Remarks
EngineId, EngineBoots, EngineTime, and User are the values received from SourceAddress.
For SNMPv3, the User parameter shows the user that was supplied with the packet. This parameter MUST be used together with the SecurityLevel parameter which shows the level of security in the message.
The SecurityLevel parameter shows whether the request has been authenticated. If SecurityLevel is 0, the request has NOT been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, SecurityLevel is 1. For an authenticated and encrypted request, SecurityLevel is 2.
Respond is True by default, and will automatically send a response using the value in LocalEngineId. To suppress the response, set Respond to False.
The value returned to SourceAddress for EngineBoots is always 0, and EngineTime is the number of seconds since January 1st, 1970 (GMT).
DiscoveryResponse Event (SNMPTCPMgr Component)
Fired when an SNMPv3 discovery response is received.
Syntax
typedef struct { String EngineId; DynamicArray<Byte> EngineIdB; int EngineBoots; int EngineTime; String User; int SecurityLevel; String SourceAddress; int SourcePort; } TipnSNMPTCPMgrDiscoveryResponseEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrDiscoveryResponseEvent)(System::TObject* Sender, TipnSNMPTCPMgrDiscoveryResponseEventParams *e); __property TipnSNMPTCPMgrDiscoveryResponseEvent OnDiscoveryResponse = { read=FOnDiscoveryResponse, write=FOnDiscoveryResponse };
Remarks
EngineId, EngineBoots, EngineTime, and User are the values received from SourceAddress and SourcePort.
The SecurityLevel parameter shows whether the request has been authenticated. If SecurityLevel is 0, the request has NOT been authenticated (i.e. the packet signature has not been verified). For an authenticated request, SecurityLevel is at least 1.
Error Event (SNMPTCPMgr Component)
Fired when information is available about errors during data delivery.
Syntax
typedef struct { int ErrorCode; String Description; } TipnSNMPTCPMgrErrorEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrErrorEvent)(System::TObject* Sender, TipnSNMPTCPMgrErrorEventParams *e); __property TipnSNMPTCPMgrErrorEvent OnError = { read=FOnError, write=FOnError };
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.
The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
HashPassword Event (SNMPTCPMgr Component)
Fired before and after a password is hashed.
Syntax
typedef struct { String Password; int AuthAlgorithm; String Hash; } TipnSNMPTCPMgrHashPasswordEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrHashPasswordEvent)(System::TObject* Sender, TipnSNMPTCPMgrHashPasswordEventParams *e); __property TipnSNMPTCPMgrHashPasswordEvent OnHashPassword = { read=FOnHashPassword, write=FOnHashPassword };
Remarks
SNMPv3 passwords are hashed in order to obtain authentication and encryption keys. This is an expensive operation, and in certain situations it may be preferable to store the hashed passwords externally and supply them on demand.
If a hash is required, the event fires with an empty string in the Hash parameter. In this case, you can choose to supply a value for the hash and stop the component from computing the hash.
The event also fires every time a hash is computed. In this case, the Hash parameter contains the value of the computed hash.
AuthAlgorithm contains either 1 for HMAC-MD5-96, 2 for HMAC-SHA-96 or 3 for HMAC-192-SHA-256
InformRequest Event (SNMPTCPMgr Component)
Fired when an InformRequest packet is received.
Syntax
typedef struct { int RequestId; int SNMPVersion; String Community; String User; int SecurityLevel; String SourceAddress; int SourcePort; int ErrorIndex; int ErrorStatus; String ErrorDescription; bool Respond; } TipnSNMPTCPMgrInformRequestEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrInformRequestEvent)(System::TObject* Sender, TipnSNMPTCPMgrInformRequestEventParams *e); __property TipnSNMPTCPMgrInformRequestEvent OnInformRequest = { read=FOnInformRequest, write=FOnInformRequest };
Remarks
The user in an InformRequest packet (SNMPv3) must match the user in the User property. If not, the request is rejected, and a BadPacket event is fired before InformRequest is fired.
The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the ObjId, ObjType, and ObjValue of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events.
The SourceAddress and SourcePort parameters show the address and port of the sender as reported by the TCP/IP stack.
The MessageId parameter identifies the received request.
For SNMPv3, the User parameter shows the user that was supplied with the packet. This parameter MUST be used together with the SecurityLevel parameter which shows the level of security in the message.
The SecurityLevel parameter shows whether the request has been authenticated. If SecurityLevel is 0, the request has NOT been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, SecurityLevel is 1. For an authenticated and encrypted request, SecurityLevel is 2.
To send a response, the Respond parameter must be set to true. By default, this value is false, which means no response will be sent. The ErrorStatus parameter may also be set to a valid SNMP status code (the default value is 0, which represents no error).
The following is a list of valid SNMP status code values:
0 (noError) | No error. |
1 (tooBig) | The response cannot fit in a single SNMP message. |
2 (noSuchName) | Variable does not exist. |
3 (badValue) | Invalid value or syntax. |
4 (readOnly) | Variable is read-only. |
5 (genError) | Other error (SNMPv1). |
6 (noAccess) | Access denied. |
7 (wrongType) | Wrong object type. |
8 (wrongLength) | Wrong length. |
9 (wrongEncoding) | Wrong encoding. |
10 (wrongValue) | Wrong value. |
11 (noCreation) | No creation. |
12 (inconsistentValue) | Inconsistent value. |
13 (resourceUnavailable) | Resource unavailable. |
14 (commitFailed) | Commit failed. |
15 (undoFailed) | Undo failed. |
16 (authorizationError) | Authorization error. |
17 (notWritable) | Variable is not writable. |
18 (inconsistentName) | Inconsistent name. |
Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).
PacketTrace Event (SNMPTCPMgr Component)
Fired for every packet sent or received.
Syntax
typedef struct { String Packet; DynamicArray<Byte> PacketB; int Direction; String PacketAddress; int PacketPort; } TipnSNMPTCPMgrPacketTraceEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrPacketTraceEvent)(System::TObject* Sender, TipnSNMPTCPMgrPacketTraceEventParams *e); __property TipnSNMPTCPMgrPacketTraceEvent OnPacketTrace = { read=FOnPacketTrace, write=FOnPacketTrace };
Remarks
The PacketTrace event shows all the packets sent or received by the component.
Packet contains the full contents of the datagram.
Direction shows the direction of the packet: 1 for incoming packets, and 2 for outgoing packets.
In the case of an incoming packet, PacketAddress and PacketPort identify the source of the packet.
In the case of an outgoing packet, PacketAddress and PacketPort identify the destination of the packet.
ReadyToSend Event (SNMPTCPMgr Component)
Fired when the component is ready to send data.
Syntax
typedef struct { } TipnSNMPTCPMgrReadyToSendEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrReadyToSendEvent)(System::TObject* Sender, TipnSNMPTCPMgrReadyToSendEventParams *e); __property TipnSNMPTCPMgrReadyToSendEvent OnReadyToSend = { read=FOnReadyToSend, write=FOnReadyToSend };
Remarks
The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend.
Report Event (SNMPTCPMgr Component)
Fired when a Report packet is received.
Syntax
typedef struct { int RequestId; int SNMPVersion; String Community; String User; int SecurityLevel; String SourceAddress; int SourcePort; int ErrorIndex; int ErrorStatus; String ErrorDescription; } TipnSNMPTCPMgrReportEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrReportEvent)(System::TObject* Sender, TipnSNMPTCPMgrReportEventParams *e); __property TipnSNMPTCPMgrReportEvent OnReport = { read=FOnReport, write=FOnReport };
Remarks
For SNMPv3, the User parameter shows the user that was supplied with the packet. This parameter MUST be used together with the SecurityLevel parameter which shows the level of security in the message.
The SecurityLevel parameter shows whether the request has been authenticated. If SecurityLevel is 0, the request has NOT been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, SecurityLevel is 1. For an authenticated and encrypted request, SecurityLevel is 2.
The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the ObjId, ObjType, and ObjValue of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events.
The SourceAddress and SourcePort parameters show the address and port of the sender as reported by the TCP/IP stack.
Response Event (SNMPTCPMgr Component)
Fired when a GetResponse packet is received.
Syntax
typedef struct { int RequestId; int SNMPVersion; String Community; String User; int SecurityLevel; String SourceAddress; int SourcePort; int ErrorIndex; int ErrorStatus; String ErrorDescription; } TipnSNMPTCPMgrResponseEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrResponseEvent)(System::TObject* Sender, TipnSNMPTCPMgrResponseEventParams *e); __property TipnSNMPTCPMgrResponseEvent OnResponse = { read=FOnResponse, write=FOnResponse };
Remarks
The ErrorStatus and ErrorIndex parameters contain information about possible errors. ErrorDescription is a textual description of ErrorStatus. This value is parsed directly from the SNMP response, which will be a one-based value, so a value of i here maps to index i-1 in the Objects collection.
The following is a list of valid SNMP status code values:
0 (noError) | No error. |
1 (tooBig) | The response cannot fit in a single SNMP message. |
2 (noSuchName) | Variable does not exist. |
3 (badValue) | Invalid value or syntax. |
4 (readOnly) | Variable is read-only. |
5 (genError) | Other error (SNMPv1). |
6 (noAccess) | Access denied. |
7 (wrongType) | Wrong object type. |
8 (wrongLength) | Wrong length. |
9 (wrongEncoding) | Wrong encoding. |
10 (wrongValue) | Wrong value. |
11 (noCreation) | No creation. |
12 (inconsistentValue) | Inconsistent value. |
13 (resourceUnavailable) | Resource unavailable. |
14 (commitFailed) | Commit failed. |
15 (undoFailed) | Undo failed. |
16 (authorizationError) | Authorization error. |
17 (notWritable) | Variable is not writable. |
18 (inconsistentName) | Inconsistent name. |
Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).
The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the ObjId, ObjType, and ObjValue of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events.
The SourceAddress and SourcePort parameters show the address and port of the sender as reported by the TCP/IP stack.
SSLClientAuthentication Event (SNMPTCPMgr Component)
Fired when the client presents its credentials to the server.
Syntax
typedef struct { String RemoteAddress; int RemotePort; String CertEncoded; DynamicArray<Byte> CertEncodedB; String CertSubject; String CertIssuer; String Status; bool Accept; } TipnSNMPTCPMgrSSLClientAuthenticationEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrSSLClientAuthenticationEvent)(System::TObject* Sender, TipnSNMPTCPMgrSSLClientAuthenticationEventParams *e); __property TipnSNMPTCPMgrSSLClientAuthenticationEvent OnSSLClientAuthentication = { read=FOnSSLClientAuthentication, write=FOnSSLClientAuthentication };
Remarks
This event fires when a client connects to the component and presents a certificate for authentication. 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 to continue or not.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK").
RemoteAddress is the IP address of the connecting client.
RemotePort is the source port of the connecting client.
CertEncoded is the base64 encoded certificate presented by the client.
CertSubject is the subject of the certificate presented by the client.
CertIssuer is the subject of the issuer of the certificate presented by the client.
Status is the stauts of the certificate.
Accept defines whether the certificate is accepted.
SSLServerAuthentication Event (SNMPTCPMgr Component)
Fires when connecting to the server.
Syntax
typedef struct { String RemoteAddress; int RemotePort; String CertEncoded; DynamicArray<Byte> CertEncodedB; String CertSubject; String CertIssuer; String Status; bool Accept; } TipnSNMPTCPMgrSSLServerAuthenticationEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrSSLServerAuthenticationEvent)(System::TObject* Sender, TipnSNMPTCPMgrSSLServerAuthenticationEventParams *e); __property TipnSNMPTCPMgrSSLServerAuthenticationEvent OnSSLServerAuthentication = { read=FOnSSLServerAuthentication, write=FOnSSLServerAuthentication };
Remarks
This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.
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.
RemoteAddress is the IP address of the server.
RemotePort is the source port of the server.
CertEncoded is the base64 encoded certificate presented by the server.
CertSubject is the subject of the certificate presented by the server.
CertIssuer is the subject of the issuer of the certificate presented by the server.
Status is the stauts of the certificate.
Accept defines whether the certificate is accepted.
SSLStatus Event (SNMPTCPMgr Component)
Shows the progress of the secure connection.
Syntax
typedef struct { String RemoteAddress; int RemotePort; String Message; } TipnSNMPTCPMgrSSLStatusEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrSSLStatusEvent)(System::TObject* Sender, TipnSNMPTCPMgrSSLStatusEventParams *e); __property TipnSNMPTCPMgrSSLStatusEvent OnSSLStatus = { read=FOnSSLStatus, write=FOnSSLStatus };
Remarks
The event is fired for informational and logging purposes only. It is used to track the progress of the connection.
RemoteAddress is the IP address of the remote machine.
RemotePort is the port of the remote machine.
Message is the log message.
Trap Event (SNMPTCPMgr Component)
Fired when a SNMP trap packet is received.
Syntax
typedef struct { int RequestId; int SNMPVersion; String Community; String User; int SecurityLevel; String TrapOID; __int64 TimeStamp; String SourceAddress; int SourcePort; } TipnSNMPTCPMgrTrapEventParams; typedef void __fastcall (__closure *TipnSNMPTCPMgrTrapEvent)(System::TObject* Sender, TipnSNMPTCPMgrTrapEventParams *e); __property TipnSNMPTCPMgrTrapEvent OnTrap = { read=FOnTrap, write=FOnTrap };
Remarks
The SNMPTrapMgr component should normally be used to receive traps, since it was designed and contains functionality specifically for that purpose. The SNMPMgr component can only receive traps from the agent that it is has most recently discovered with the Discover method.
The TrapOID and TimeStamp parameters contain the Trap OID and TimeStamp. In the case of an SNMPv1 trap, there are two possible scenarios:
First, if the enterprise of the trap is "1.3.6.1.6.3.1.1.5", TrapOID will be a concatenation of TrapEnterprise and GenericTrap + 1. For instance a TrapOID of "1.3.6.1.6.3.1.1.5.5" has a TrapEnterprise of "1.3.6.1.6.3.1.1.5" and a GenericTrap of "4".
Second, In all other cases TrapOID will be a concatenation of the values for TrapEnterprise, GenericTrap, and SpecificTrap, separated by '.'.
For SNMPv2 and above, they are read from the variable-value list (if available).
For SNMPv3, the User parameter shows the user that was supplied with the packet. This parameter MUST be used together with the SecurityLevel parameter which shows the level of security in the message.
The SecurityLevel parameter shows whether the request has been authenticated. If SecurityLevel is 0, the request has NOT been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, SecurityLevel is 1. For an authenticated and encrypted request, SecurityLevel is 2.
The SNMPMgr component is limited to accepting authenticated traps only for the user specified in User and Password and from the engine specified in RemoteEngineId with time parameters in RemoteEngineBoots and RemoteEngineTime (usually this is the SNMP engine discovered through the last call to Discover). If authenticated traps come from a different engine, or for a different user, they are ignored, and a BadPacket event is fired instead.
The list of variables in the SNMP packet, including optional values and types, is provided through the Objects collection. Each object is of type SNMPObject. This type describes the ObjId, ObjType, and ObjValue of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events.
The SourceAddress and SourcePort parameters show the address and port of the sender as reported by the TCP/IP stack.
Config Settings (SNMPTCPMgr Component)
The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.SNMPTCPManager Config Settings
0 (default) | Component operates normally for greatest compatibility. |
1 | Component uses SNMP4j-compatible encryption (AES192 and AES256). |
2 | Component automatically detects whether to use SNMP4j-compatible encryption (AES192 and AES256). Note: This option is only applicable when receiving packets. If you are using SNMPMgr or sending secure traps, you will need to select either 0 or 1. |
Note that when StoreWalkObjects is set to true and WalkStartOID is set, the existing entries in Objects will be maintained when Walk is called and new returned objects will be added (just as if no error occurred in the initial Walk call).
TCPClient Config Settings
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 components that do not directly expose Firewall properties.
Note: This setting is provided for use by components that do not directly expose Firewall properties.

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 components that do not directly expose Firewall properties.

Note: This value is not applicable in macOS.
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 component 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.
If the component is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
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 config 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 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 etc). OpenSSL recommends to use 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
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please 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 component 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 component is the same.

When set to 0 (default) the CRL check will not be performed by the component. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.
This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
When set to 0 (default) the component will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.
This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the component will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.
Example values when SSLProvider is set to Platform:
obj.config("SSLEnabledCipherSuites=*");

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 value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default) |
TLS1.1 | 768 (Hex 300) (Default) |
TLS1 | 192 (Hex C0) (Default) |
SSL3 | 48 (Hex 30) [Platform Only] |
SSL2 | 12 (Hex 0C) [Platform Only] |
SSLEnabledProtocols - TLS 1.3 Notes
By default when TLS 1.3 is enabled the component will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions which 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 only supported 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 only available 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 the above 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 component 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 setting is only applicable 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 component 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 traffice for debugging purposes. When writing to this file the component will only append, it will not overwrite previous values.
Note: This setting is only applicable when SSLProvider is set to Internal.

This functionality is currently not available when the provider is OpenSSL.
The value of this setting is a newline (CrLf) separated list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the component will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the component raises an exception.
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 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.
In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The 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 setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.
The default value is ecdhe_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"

- "rsa_pss_sha256" (default)
- "rsa_pss_sha384" (default)
- "rsa_pss_sha512" (default)
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:

Note: This option is not valid for UDP ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
