HTMLMailer Control
Properties Methods Events Config Settings Errors
The HTMLMailer Control is used to send HTML emails, including embedded images.
Syntax
HTMLMailer
Remarks
The HTMLMailer Control supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections (RFC 2487). When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.
The control sends a message (provided in MessageHTML and MessageText). The HTML message may contain references to images that are automatically embedded into the message.
The MessageHTML property contains the HTML version of the message. The corresponding plaintext version is provided in the MessageText property.
When MessageHTML is set, the control automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.
The recipients are specified by the SendTo, Cc, and BCc properties, and the message subject by the Subject property.
Once all the appropriate properties have been set, call the Send method and your message will be sent to its intended recipient(s).
Other SMTP headers may be specified through the OtherHeaders property. Information about interaction with the server is provided by the PITrail event.

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).
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertStoreB.
This property is read-only.

SSLServerCertSubject Property (HTMLMailer Control)
The subject of the certificate used for client authentication.
Syntax
htmlmailercontrol.SSLServerCertSubject
Default Value
""
Remarks
The subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the property is set to the full subject of the matching certificate.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.

String
SSLServerCertEncoded Property (HTMLMailer Control)
The certificate (PEM/Base64 encoded).
Syntax
htmlmailercontrol.SSLServerCertEncoded
Default Value
""
Remarks
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.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.
This property is read-only and not available at design time.
Data Type
Binary String
SSLStartMode Property (HTMLMailer Control)
This property determines how the control starts the Secure Sockets Layer (SSL) negotiation.
Syntax
htmlmailercontrol.SSLStartMode[=integer]
Possible Values
sslAutomatic(0), sslImplicit(1), sslExplicit(2)
Default Value
0
Remarks
The SSLStartMode property may have one of the following values:
0 (sslAutomatic) | If the remote port is set to the standard plaintext port of the protocol (where applicable), the control will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit). |
1 (sslImplicit) | The SSL negotiation will start immediately after the connection is established. |
2 (sslExplicit) | The control will first connect in plaintext, and then will explicitly start SSL negotiation through a protocol command such as STARTTLS. |
Data Type
Integer
Subject Property (HTMLMailer Control)
This property includes the subject of the mail message (optional).
Syntax
htmlmailercontrol.Subject[=string]
Default Value
""
Remarks
The string in this property is sent with a Subject SMTP header to the mail recipient.
If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.
Data Type
String
Timeout Property (HTMLMailer Control)
The timeout for the control.
Syntax
htmlmailercontrol.Timeout[=integer]
Default Value
60
Remarks
If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.
If Timeout is set to a positive value, the control will wait for the operation to complete before returning control.
The control 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 control fails with an error.
Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.
Data Type
Integer
User Property (HTMLMailer Control)
This property includes the user identifier needed to log in as in the MailServer .
Syntax
htmlmailercontrol.User[=string]
Default Value
""
Remarks
If this property is set to a nonempty string, then when connecting to the MailServer an AUTH or CRAM-MD5 (depending on the value of AuthMechanism) command is sent to provide authentication information for the user.
This property is not available at design time.
Data Type
String
AddAttachment Method (HTMLMailer Control)
This adds FileName as an attachment.
Syntax
htmlmailercontrol.AddAttachment FileName
Remarks
This method adds the file name as an attachment. The full list of attachments is contained in the Attachments property.
Example 1: Adding an Attachment
component.AddAttachment("C:\file1.zip");
component.AddAttachment("C:\file2.zip");
component.Send();
Example 3: Using an Attachments Array
component.AttachmentCount = 1;
component.AttachmentName(0) = "name";
component.AttachmentFile(0) = "C:\file.txt";
CalcMessageText Method (HTMLMailer Control)
This method populates MessageText with the plaintext version of the message.
Syntax
htmlmailercontrol.CalcMessageText
Remarks
This method parses MessageHTML or HTMLFile and calculates a plaintext version of the message. The plaintext version is stored in the MessageText property.
Calling this method is optional. When the Send method is called, the control will automatically calculate a plaintext version of the message. This may be called in cases in which the plaintext version will be set explicitly. For instance:
component.MessageHTML="<html><body><b>Test Message</b></body></html>";
component.CalcMessageText();
component.MessageText = "A new custom plaintext message";
Config Method (HTMLMailer Control)
Sets or retrieves a configuration setting.
Syntax
htmlmailercontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These 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.
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.
Connect Method (HTMLMailer Control)
This method connects to the mail relay and sends the SMTP HELO command.
Syntax
htmlmailercontrol.Connect
Remarks
This method connects to the mail relay and sends the SMTP HELO command, thus preparing to send messages. Any number of messages can later be sent using the Send method.
Example. Connecting and Sending an Email:
control.MailServer = "MyServer"
control.From = "me@server.com"
control.SendTo = "recipient@server.com"
control.Subject = "My Subject"
control.MessageText = "This is the message body"
control.Connect()
control.Send()
control.Disconnect()
Disconnect Method (HTMLMailer Control)
This method disconnects from the SMTP server.
Syntax
htmlmailercontrol.Disconnect
Remarks
This method disconnects from the mail relay.
DoEvents Method (HTMLMailer Control)
This method processes events from the internal message queue.
Syntax
htmlmailercontrol.DoEvents
Remarks
When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Interrupt Method (HTMLMailer Control)
This method interrupts the current method.
Syntax
htmlmailercontrol.Interrupt
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
ProcessQueue Method (HTMLMailer Control)
This method sends the messages that previously have been queued into QueueDir .
Syntax
htmlmailercontrol.ProcessQueue QueueDir
Remarks
This method sends the messages that previously have been queued into QueueDir. The PITrail event shows the interaction with the server as messages are processed.
This method looks in the directory for files with the extension ".queued" and starts processing them.
When processing starts, the file extension is changed to ".sending". If an error happens at this stage, the sending process is aborted, and the file extension is changed to ".failed".
If the file is successfully sent, the file is normally deleted, unless the KeepQueue configuration setting is set to True, in which case the file extension is instead changed to ".sent" and the queue file is not deleted.
Queue Method (HTMLMailer Control)
This method queues the message into QueueDir .
Syntax
htmlmailercontrol.Queue QueueDir
Remarks
This method queues the message into QueueDir. The message is queued into a unique file into the directory QueueDir for future processing.
QueueDir must already exist, or an error will be generated. Alternatively, QueueDir may be set to "*" to return the result as a string instead of writing it to a file.
This method returns the name of the unique queue file created in QueueDir. The file extension is ".queued".
Please refer to the ProcessQueue method for more information on email queue processing.
Reset Method (HTMLMailer Control)
This method will reset the control.
Syntax
htmlmailercontrol.Reset
Remarks
This method will reset the control's properties to their default values.
ResetHeaders Method (HTMLMailer Control)
This method resets all the message headers to empty.
Syntax
htmlmailercontrol.ResetHeaders
Remarks
This method resets all the message headers to "" (empty string). Use this method before creating a new message, so that headers from the previous message are not carried over to the next one.
Send Method (HTMLMailer Control)
This method sends the current message and MIME-encoded attachment.
Syntax
htmlmailercontrol.Send
Remarks
This method sends the current message and MIME-encoded attachment. If the control is not connected to the mail relay, a connection is created, the message is sent, and then the connection is closed unless an error occurs.
If the control is already connected (by use of the Connect method), the connection will remain open after the message is sent. To disconnect, call the Disconnect method.
Example. Send an HTML Email:
HTMLMailerControl.MailServer = "myserver"
HTMLMailerControl.SendTo = "recipient@myserver.com"
HTMLMailerControl.From = "me@myserver.com"
HTMLMailerControl.Subject = "My Subject"
HTMLMailerControl.MessageHTML = "<b>Hello</b>, my name is <i>Tom</i>"
HTMLMailerControl.Send
SendCommand Method (HTMLMailer Control)
This method sends the exact command directly to the server.
Syntax
htmlmailercontrol.SendCommand Command
Remarks
This method sends the command specified by Command to the server exactly as it is provided. Use this method to send additional or custom commands directly to the server.
After calling this method, check the LastReply property or monitor the PITrail event to obtain the server's response.
ConnectionStatus Event (HTMLMailer Control)
Fired to indicate changes in the connection state.
Syntax
Sub htmlmailercontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)
Remarks
This event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.
The ConnectionEvent parameter indicates the type of connection event. Values may include the following:
Firewall connection complete. | |
Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | |
Remote host connection complete. | |
Remote host disconnected. | |
SSL or S/Shell connection broken. | |
Firewall host disconnected. |
EndTransfer Event (HTMLMailer Control)
This event is fired when the message text completes transferring.
Syntax
Sub htmlmailercontrol_EndTransfer(Direction As Integer)
Remarks
If MessageText is not empty, the EndTransfer event is fired when the MessageText finishes transferring from the local host to the MailServer. If MessageText is empty, the event is not fired.
If a file is attached to the MessageText via the AttachedFile property, then EndTransfer fires again when the file finishes transferring. For more information, go to the description of the AttachedFile property.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Error Event (HTMLMailer Control)
Fired when information is available about errors during data delivery.
Syntax
Sub htmlmailercontrol_Error(ErrorCode As Integer, Description As String)
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.
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.
PITrail Event (HTMLMailer Control)
This event traces the commands sent to the mail server, and the respective replies.
Syntax
Sub htmlmailercontrol_PITrail(Direction As Integer, Message As String)
Remarks
The PITrail event is useful for debugging purposes. It shows all of the interaction between the client and the server, line by line, except for message header and body transfers.
The Message parameter contains the full text of the message. The Direction parameter shows the originator of the message:
0 (Client) | The Message originates from the client. |
1 (Server) | The Message originates from the server. |
2 (Info) | The Message is an informative message originating from the client software (the control code). |
SSLServerAuthentication Event (HTMLMailer Control)
Fired after the server presents its certificate to the client.
Syntax
Sub htmlmailercontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (HTMLMailer Control)
Fired when secure connection progress messages are available.
Syntax
Sub htmlmailercontrol_SSLStatus(Message As String)
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
StartTransfer Event (HTMLMailer Control)
This event is fired when the message text starts transferring.
Syntax
Sub htmlmailercontrol_StartTransfer(Direction As Integer)
Remarks
If MessageText is not empty, the StartTransfer event is fired when the MessageText starts transferring from the local host to the MailServer. If MessageText is empty, the event is not fired.
If a file is attached to the MessageText via the AttachedFile property, then StartTransfer fires again when the file starts transferring. Please go to the description of the AttachedFile property for more information.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Transfer Event (HTMLMailer Control)
This event is fired when the message text is transferred to MailServer .
Syntax
Sub htmlmailercontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)
Remarks
One or more Transfer events are fired during message delivery. Messages consist of MessageText and an optional AttachedFile. The BytesTransferred parameter shows the number of bytes sent starting from the beginning of MessageText or AttachedFile.
Text contains the current portion of the message being sent.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.
Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
Config Settings (HTMLMailer 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.HTMLMailer Config Settings
0 | 7-bit |
1 | Quoted-Printable |
2 | Base64 |
3 | 8-bit |

SMTP Config Settings
Bearer ya29.AHES6ZRmS-8xPbpGetC1VbABJIBRdKm-c4X7wMVGAbgxdGt5q8Ts3Q
Note: When using amXOAUTH2, User must be specified, but Password is not required.
If AllowExtensions is True, the EHLO command will be sent instead of the HELO command.
It is generally a good idea to use a MaxHeaderLength of less than 100 bytes, although different mail relays and mail servers have different requirements for header lengths.
Example:
smtp1.Send();
string rawMsg = smtp1.Config("MessageHeadersString") + smtp1.Config("TransferText");
Possible values are as follows:
- "MD5"
- "SHA1" (default)
- "SHA256"
Example:
smtp1.Send();
string rawMsg = smtp1.Config("MessageHeadersString") + smtp1.Config("TransferText");
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 controls that do not directly expose Firewall properties.
Note: This setting is provided for use by controls that do not directly expose Firewall properties.
Note: This configuration setting is provided for use by controls 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 controls that do not directly expose Firewall properties.
Note: This setting is provided for use by controls 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 control returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.
If the control is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.
www.google.com;www.nsoftware.com
Note: This value is not applicable in Java.
By default, this configuration setting is set to False.
0 | IPv4 only |
1 | IPv6 only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this configuration setting has no effect if SSLProvider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
If set to True, the 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.

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

0x00000010 | Allow unknown certificate authority. |
0x00000020 | Ignore wrong certificate usage. |
0x00000100 | Ignore unknown certificate revocation status. |

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"

- "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:
