OFTPServer Control
Properties Methods Events Config Settings Errors
The OFTPServer control implements the server side of the Odette File Transfer Protocol.
Syntax
OFTPServer
Remarks
The OFTPServer component implements an OFTP server. It is a lightweight server that supports version 1.2, 1.3, 1.4, and 2.0 of OFTP.
Sending and Receiving Files
To use the control first decide if you will support TLS/SSL connections or not. If UseSSL is set to true, all clients will be expected to connect in TLS/SSL. If UseSSL is set to false (default), all clients are expected to connect in plaintext. If UseSSL is true, only clients that support Version 2.0 of the protocol can connect.
Once you have decided whether or not to support TLS/SSL, specify the port you wish the server to listen on in LocalPort. By default this value is 3305.
Next, specify values for ServerSSIDCode, ServerSFIDCode, ServerPassword.
Then set Listening to true to start listening for incoming requests.
When a client connects, you will have an opportunity to authenticate the client before continuing the connection.
This is done when the AcceptConnection event fires. Within this event you can validate that the connecting client
has access based on rules you determine. If you wish to reject the connection set the Accept parameter to false.
Within this event you can also specify the directory to which files sent by the client to the server are saved.
It is necessary to specify the directory within this event, as the client can start sending files as soon as the connection is complete. To specify
the download directory set the OFTPConnectionDownloadDirectory property. For instance:
oftpserver1.SetOFTPConnectionDownloadDirectory(e->ConnectionId, "C:\\Downloads");
When the connection is complete, the client may send files. If the client does send a file the AcceptFile event will fire and you will have the opportunity to reject the file by setting the Accept parameter of the event. In addition you will have a chance to change the filename by setting the Filename parameter if desired.
After the client has sent all the files it is configured to send, it will pass control to the server. At that time the ReadyToSend event will fire, and the OFTPConnectionReadyToSend property will be set to true. After this, you can either end the session with the client by calling Logoff or send files to the client. To send files to the client simply call the SendFile method with the specified parameters.
TLS/SSL Notes
When UseSSL is set to true, the server must be configured with a TLS/SSL certificate before it is started. Set SSLCert to a valid certificate with corresponding private key before setting Listening to true. This may be a PFX file, PEM key, or a certificate in a windows certificate store. See the SSLCert property for more information.
After SSLCert is set to a valid certificate and Listening is set to true, when a client connects the SSLStatus event will fire during the TLS/SSL negotiation. This is purely informational, if there is an error the Error event will fire.
If you want to require TLS/SSL client authentication, set SSLAuthenticateClients to true before setting Listening to true. This will force clients to present a certificate during TLS/SSL negotiation to be used for authorization. In this case the SSLClientAuthentication event will fire and you must set the Accept parameter within the event to true in order to accept the client's certificate and proceed with the connection.
Example Code
MyOftpserver server;
server.SetServerSSIDCode("SERVERSSID");
server.SetServerSFIDCode("SERVERSFID");
server.SetServerPassword("SERVER");
server.SetListening(true);
...
//Within the main loop of the application call server.DoEvents() in a loop
//to process events.
//When the ReadyToSend event fires the server can then send files to the client. To do this call the SendFile method.
//Alternatively, monitor server.GetOFTPConnectionReadyToSend(<ConnectionId>) to determine when files can be sent.

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
oftpservercontrol.LocalHost[=string]
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 control initiate connections (or accept in the case of server controls) 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 control is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Note: LocalHost is not persistent. You must always set it in code, and never in the property window.
Data Type
String
LocalPort Property (OFTPServer Control)
The TCP port in the local host where the control listens.
Syntax
oftpservercontrol.LocalPort[=integer]
Default Value
3305
Remarks
This property must be set before OFTPServer starts listening. If its value is 0, then the TCP/IP subsystem picks a port number at random. The port number can be found by checking the value of this property after OFTPServer is in listening mode (after successfully assigning True to the Listening property).
The service port is not shared among servers (i.e. there can be only one OFTPServer 'listening' on a particular port at one time).
The default value for plaintext communication is 3305. If UseSSL is set to true, set this value to 6619 (the default port for SSL communication).

Imports a list of trusted CA certificates.
Syntax
oftpservercontrol.ImportTrustedCerts
Remarks
When ImportTrustedCerts is called the control will import the CA certificates from the source specified by TrustedCertsData into the TrustedCerts collection.
The control will then validate the trust of certificates when they are loaded.
If trusted CA certificates are not imported no validation will occur (default).
See also FailOnUntrustedCert.
Interrupt Method (OFTPServer Control)
This method interrupts a synchronous send to the remote host.
Syntax
oftpservercontrol.Interrupt ConnectionId
Remarks
This property is called using the Connection Id if you wish to interrupt a connection and stop a file from uploading without disconnecting the client connected to the control. If you use SendFile to upload a file, the control will run synchronously on that Connection Id until it is completed.
Logoff Method (OFTPServer Control)
Ends a session with the connection client.
Syntax
oftpservercontrol.Logoff ConnectionId
Remarks
This method will attempt to end the session with the client if the client has acknowledged it is finished sending files to the server. If the client still wishes to process commands, the method will give control back to the client and OFTPConnectionReadyToSend will be false. When OFTPConnectionReadyToSend is true, calling this method will end the session.
Reset Method (OFTPServer Control)
Resets the state of the control.
Syntax
oftpservercontrol.Reset
Remarks
Reset resets the state of the control. All properties will be set to their default values.
SendEndResponse Method (OFTPServer Control)
Sends an EERP/NERP asynchronously.
Syntax
oftpservercontrol.SendEndResponse ConnectionId, VirtualFileName, VirtualFileDate, Destination, Originator, Creator, ReasonCode, ReasonText, FileHash, Signature
Remarks
This method sends an EERP/NERP. By default the control will automatically respond with an EERP/NERP when receiving a file. To respond asynchronously instead this method may be used.
To respond asynchronously first set the SendEndResponse parameter of the EndTransfer event to False. This instructs the control to not send a response automatically. Within the EndTransfer event you must also save the values that are required parameters for this method. This includes FileHash, VirtualFileDate, and VirtualFileName. Note: VirtualFileDateFormat must be set to a format that includes the necessary level of accuracy.
Destination should be set to the SFID of the remote host.
Originator should be set to the SFID of the local system. In the case that the control is being used as part of a gateway process to forward traffic to another OFTP host this may be set to the SFID of that host instead.
Creator should be set to the SFID of the local system.
Signature is only applicable if the application is acting as a routing application. In all other cases this should be set to empty string. In the case where the application is acting as a routing application the end response is being forwarded to another entity for processing. The Signature should be set to the value received in the EndResponse event (if populated).
ReasonCode and ReasonText are used to specify error information. If ReasonCode is set to 0 the control will send an EERP. If ReasonCode is set to any non-zero value the control will send a NERP. Common values are:
ReasonCode | ReasonText |
3 | User Code Not Known |
4 | Invalid Password |
9 | Unspecified Reason |
11 | Invalid FileName |

SendFile Method (OFTPServer Control)
Sends a file to the specified client.
Syntax
oftpservercontrol.SendFile ConnectionId, ClientSFIDCode, FileName, VirtualFileName
Remarks
This method sends a file to the client specified by the ConnectionId parameter.
After the ReadyToSend event fires or when the OFTPConnectionReadyToSend property is true, this method can be used to send a file to the connected client specified by the ConnectionId parameter.
The ClientSFIDCode corresponds to the destination.
FileName must be the full path to the file which will be sent.
VirtualFileName may be specified to indicate the name of the file that the client will see when receiving the file.
If ConnectionsUploadStream is set, pass empty string as the value for the FileName parameter.
When this method is called, the control will fire the StartTransfer, Transfer, and EndTransfer events that can be monitored to check the status of the send. The SendFile method will not return until either the transfer is complete or an error was encountered.
Shutdown Method (OFTPServer Control)
This method shuts down the server.
Syntax
oftpservercontrol.Shutdown
Remarks
This method shuts down the server. Calling this method is equivalent to calling StopListening and then breaking every client connection by calling Disconnect.
StartListening Method (OFTPServer Control)
This method starts listening for incoming connections.
Syntax
oftpservercontrol.StartListening
Remarks
This method begins listening for incoming connections on the port specified by LocalPort. Once listening, events will fire as new clients connect and data are transferred.
To stop listening for new connections, call StopListening. To stop listening for new connections and to disconnect all existing clients, call Shutdown.
StopListening Method (OFTPServer Control)
This method stops listening for new connections.
Syntax
oftpservercontrol.StopListening
Remarks
This method stops listening for new connections. After being called, any new connection attempts will be rejected. Calling this method does not disconnect existing connections.
To stop listening and to disconnect all existing clients, call Shutdown instead.
ValidateCert Method (OFTPServer Control)
Validates the certificate with private key.
Syntax
oftpservercontrol.ValidateCert
Remarks
This method optionally validates the certificate specified by Certificate. It is not required to validate the certificate from a technical perspective, but may be desired to ensure the recipient's certificate is valid and issued by a trusted authority.
Before calling this method call ImportTrustedCerts to load the trusted certification information.
When this method is called the control:
- Validates the certificate has not expired
- Validates the certificate was issued by a CA in the TrustedCerts collection. If the certificate is self-signed this step is skipped.
- Validates the certificate has not been revoked. Note that the revocation check will only make use of the CRL distribution point identified in the certificate's extension. If the certificate does not contain a CRL distribution point extension this step is skipped.
ValidateRecipientCert Method (OFTPServer Control)
Validates the recipient certificate.
Syntax
oftpservercontrol.ValidateRecipientCert ConnectionId
Remarks
This method optionally validates the certificate specified by OFTPConnectionRecipientCertSubject. It is not required to validate the certificate from a technical perspective, but may be desired to ensure the recipient's certificate is valid and issued by a trusted authority.
Before calling this method call ImportTrustedCerts to load the trusted certification information.
When this method is called the control:
- Validates the certificate has not expired
- Validates the certificate was issued by a CA in the TrustedCerts collection. If the certificate is self-signed this step is skipped.
- Validates the certificate has not been revoked. Note that the revocation check will only make use of the CRL distribution point identified in the certificate's extension. If the certificate does not contain a CRL distribution point extension this step is skipped.

Fired when a client connects.
Syntax
Sub oftpservercontrol_AcceptConnection(ConnectionId As Integer, ClientSSIDCode As String, ClientPassword As String, ClientVersion As Integer, ServerVersion As Integer, Accept As Boolean, ErrorCode As Integer, ErrorDescription As String)
Remarks
This event fires when a new OFTP connection is made to the server. Use the parameters of this event to verify the identify of the client identified by the ConnectionId. By default the connection will be accepted. To reject the connection set Accept to false.
ClientVersion specifies the OFTP protocol version the client supports. By default the control will use the version requested by the client for the connection. If you wish to restrict connections to a specific OFTP protocol version use this value when determining whether or not to accept the connection. When rejecting the connection based on the OFTP protocol version use ErrorCode 10. Possible values are:
0 | OFTP 1.2 |
1 | OFTP 1.3 |
2 | OFTP 1.4 |
3 | OFTP 2.0 |
ServerVersion specifies the OFTP protocol version the server will use for the connection. By default this will be the same as ClientVersion. This may be set to a different version which will be sent back to the client. Possible values are:
0 | OFTP 1.2 |
1 | OFTP 1.3 |
2 | OFTP 1.4 |
3 | OFTP 2.0 |
When rejecting a connection the ErrorCode and ErrorDescription may optionally be set. Possible common values are:

CertificateReceived Event (OFTPServer Control)
Fired when a certificate is received from the remote host.
Syntax
Sub oftpservercontrol_CertificateReceived(ConnectionId As Integer, CertificateFileName As String, CertificateExchangeType As Integer)
Remarks
This event provides information about the certificate file that was sent by the remote host.
When the remote host sends a certificate using the Certificate Exchange feature of OFTP 2.0, this event provides information about it. The certificate file will be written to the DownloadDirectory. After the file is written to DownloadDirectory this event will fire.
The CertificateFilemame parameter holds the filename of the received certificate.
The CertificateExchangeType parameter identifies the type of request associated with the certificate. Possible values are:
0 | Request: The control received a certificate and request from the remote host. Respond using the ExchangeCertificate method using a CertificateExchangeType of 3 (Deliver). The response may be in a separate session. |
1 | Replace: The control received a certificate from the remote host. No response is expected. The certificate received here invalidates any previously stored certificates for this configuration. |
2 | Deliver: The control received a certificate from the remote host. This is either a response to a certificate request, or a new additional certificates from the remote host. This will not invalidate previous certificates stored for this configuration. |
ConnectionId identifies the connected client.
Connected Event (OFTPServer Control)
This event is fired immediately after a connection completes (or fails).
Syntax
Sub oftpservercontrol_Connected(ConnectionId As Integer, StatusCode As Integer, Description As String)
Remarks
If the connection is made normally, StatusCode is 0, and Description is "OK".
If the connection fails, StatusCode has the error code returned by the system. Description contains a description of this code. The value of StatusCode is equal to the value of the system error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.
Please refer to the Error Codes section for more information.
ConnectionRequest Event (OFTPServer Control)
This event is fired when a request for connection comes from a remote host.

VirtualFileDate holds the VirtualFileDate value in the format specified by VirtualFileDateFormat. The default value is "MM/dd/yyyy HH:mm:ss".
Destination is the SFID of the destination system (this control).
Originator identifies the system that originated the end response. This is typically the same as Creator and holds the remote system's SFID.
Creator is the SFID of the remote system.
Direction specifies whether the end response is being received or sent. Possible values are:
0 | Received |
1 | Sent |
FileHash is populated if the OFTP Version is 2.0 and a signed receipt was originally requested. FileHash may also be specified with the expected value in the case where an asynchronous EndResponse is received. The expected value may be obtained from the EndTransfer event when initially sending the file.
Signature is only applicable when the OFTP version is 2.0 and the application is acting as a routing application where the end response will be forwarded on to another entity. In this case Signature will be populated if the end response is signed. This should be stored and supplied when forwarding the response with the SendEndResponse method.
ReasonCode and ReasonText identify the error if a Negative End Response (NERP) was received. A value of 0 indicates there was no an error and the response is an End-To-End Response (EERP). Common values are:
ReasonCode | ReasonText |

LocalFile holds the full path to the file that will be written.
ConnectionId identifies the connected client.
Config Settings (OFTPServer Control)
The control 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 control, access to these internal properties is provided through the Config method.OFTPServer Config Settings
component.Config("AllowRetry[" + e->ConnectionId + "]");
When set to False (default) the component will send a value indicating the client should not retry the send operation.
The CertificateStoreType specifies the type of the certificate store specified by CertificateStore. If the store is password protected, specify the password in CertificateStorePassword.
CertificateStore is used in conjunction with the CertificateSubject field in order to specify the certificate.
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).
0 | User - This is the 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 | Machine - For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java. |
2 | PFXFile - The certificate store is the name of a PFX (PKCS12) file containing certificates. |
3 | PFXBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS12) format. |
4 | JKSFile - The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is available only in Java. |
5 | JKSBlob - 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 available only in Java. |
6 | PEMKeyFile - The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate. |
7 | PEMKeyBlob - The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate. |
14 | PPKFile - The certificate store is the name of a file that contains a PPK (PuTTY Private Key). |
15 | PPKBlob - The certificate store is a string (binary) that contains a PPK (PuTTY Private Key). |
16 | XMLFile - The certificate store is the name of a file that contains a certificate in XML format. |
17 | XMLBlob - The certificate store is a string that contains a certificate in XML format. |
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.

This may be set within the AcceptConnection event. It only applies to the connection parameters sent by the server to the client. It does not return the value sent by the client to the server. Valid values are:
0 | Both (Default) |
1 | Send Only |
2 | Receive Only |
component.Config("ConnectionType[" + e->ConnectionId + "]=1");
To check the value sent by the client to the server query ReceivedConnectionType[ConnectionId]; instead.
When establishing a connection the smaller of the two values provided by the client and the server will be used. This setting may also be queried after a connection is established to determine the negotiated value.
For instance:
string receivedCreditCount = component.Config("CreditCount[" + e->ConnectionId + "]");
component.Config("CreditCount[" + e->ConnectionId + "]=55");
This only applies to clients that have not sent or received data within DefaultIdleTimeout seconds.
If set to 0 (default) no idle timeout is applied.
Note: DoEvents must be called in order for the control to check existing connections.
0 | sha1 (Default) |
1 | sha256 |
2 | sha512 |
When this is set to True (default) and there is an error during processing the original unprocessed file will be deleted and no files will be placed in DownloadDirectory.

2 | sha512 |
0 (default) | Never follow redirects. An exception will be thrown. |
1 | Always follow redirects. The redirect will be automatically followed. |
2 | Follow same scheme redirects. Follow the redirect if it matches the same scheme (http:// or https://). |
For instance:
component.Config("IdleTimeout[" + e->ConnectionId + "]=1");
Note: DoEvents must be called in order for the control to check existing connections.
Please note that system TCP/IP stack implementations are not required to support SO_KEEPALIVE.
This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.
The default behavior (which is also the default mode for stream sockets) might result in an indefinite delay in closing the connection. Although the control returns control immediately, the system might indefinitely hold system resources until all pending data is sent (even after your application closes). This means that valuable system resources might be wasted.
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you have sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.
This property is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.
0 (None) | No messages are logged. |
1 (Info - Default) | Informational events such as OFTP commands which are sent and received. |
2 (Verbose) | Detailed data such as individual packet information is logged. |
3 (Debug) | Debug data including all relevant sent and received bytes are logged. |
This setting returns the type of connection being created. This may be queried within the AcceptConnection event or any time after. It only applies to the connection parameters sent by the client to the server. Valid values are:

When set to True, this overrides the default behavior and will always send a CD command regardless of whether the indicator is set in the EFPA.
This should only be set if there is a specific reason to do so. In most cases it is not necessary.
- OFTPConnectionCompress is true
- OFTPConnectionVirtualFileSecurityLevel is set to slEncrypted
- OFTPConnectionVirtualFileSecurityLevel is set to slSigned
- OFTPConnectionVirtualFileSecurityLevel is set to slEncryptedAndSigned
Note that OFTPConnectionVirtualFileSecurityLevel is only applicable when OFTPConnectionVersion is set to oftpVer20.
This configuration setting can be set with or without a ConnectionId specified. When the ConnectionId is specified, this will cause temporary files for that connection to be written to the specified directory. Otherwise, if no ConnectionId is specified, temporary files for all connections will be written to the given folder.
When using OFTP v2.0 If the control is configured to respond to EERP and NERP messages asynchronously this should be set to the value "yyyyMMddHHmmssffff" or a similar format that includes the same level of accuracy. This is required to ensure that when calling SendEndResponse the value saved from within the EndTransfer event has the necessary data when sending a response.
TCPServer Config Settings
When a client connects, the client's address is checked against the list defined here. If there is no match, the ConnectionRequest event fires with an Accept value set to . If no action is taken within the ConnectionRequest event, the client will be disconnected.
When a client connects, the client's address is checked against the list defined here. If there is a match, the ConnectionRequest event fires with an Accept value set to . If no action is taken within the ConnectionRequest event, the client will not be connected.
Note: This is applicable only to incoming SSL connections. This should be set only if there is a specific reason to do so.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated, the InBufferSize reverts to its defined size. The same thing will happen if you attempt to make it too large or too small.
InBufferSize is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.
Note: This value is not applicable in macOS.
Note: Unix/Linux operating systems limit the number of simultaneous connections to 1024.

SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this configuration setting has no effect if SSLProvider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
If set to True, the control 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 control is the same.

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

By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the control 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.

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
TLS1.1 | 768 (Hex 300) (Default - Client) |
TLS1 | 192 (Hex C0) (Default - Client) |
SSL3 | 48 (Hex 30) |
SSL2 | 12 (Hex 0C) |
Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.
SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:
By default when TLS 1.3 is enabled, the control 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 control when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This configuration setting is applicable only when SSLProvider is set to Internal.
If set to True, all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
When set, the control 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 control will only append, it will not overwrite previous values.
Note: This configuration setting is applicable only when SSLProvider is set to Internal.

This functionality is currently not available when the provider is OpenSSL.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the control 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 control fails with an error.
The format of this value is a comma-separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.
To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.
In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1"
- "ffdhe_2048" (default)
- "ffdhe_3072" (default)
- "ffdhe_4096"
- "ffdhe_6144"
- "ffdhe_8192"
- "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 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)
- "ecdhe_x448" (default)
- "ecdhe_secp256r1" (default)
