POP Class
Properties Methods Events Config Settings Errors
The POP Class is used to easily retrieve electronic mail from internet post office servers (POP).
Syntax
POP
Remarks
The POP Class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections (RFC 2595). When connecting over 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 via the Config method.
The POP Class implements a standard internet post office (POP3) client as specified in RFC 1725.
To connect to a MailServer, first set the appropriate User and Password and then connect by calling the Connect method. Upon successful connection to the MailServer, the number of waiting messages is shown by the MessageCount property. A message is selected by setting the MessageNumber property to a number between 1 and MessageCount (inclusive). Then, the message text and headers are received by calling the Retrieve method.
The message text is received through the Transfer event, whereas the message headers are received through the Header event. Additionally, up to MaxLines from the message body are provided in the MessageText property. The body of the message is also saved in the file specified by the LocalFile property. StartTransfer and EndTransfer events are fired at the beginning and end of message transmission. The PITrail event provides a trace of the interaction between the client and server (excluding message transfers).

Data Type
Integer
Timeout Property (POP Class)
A timeout for the class.
Syntax
ANSI (Cross Platform) int GetTimeout();
int SetTimeout(int iTimeout); Unicode (Windows) INT GetTimeout();

int ipworks_pop_gettimeout(void* lpObj);
int ipworks_pop_settimeout(void* lpObj, int iTimeout);
int GetTimeout();
int SetTimeout(int iTimeout);
Default Value
60
Remarks
If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.
If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.
The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.
If Timeout expires, and the operation is not yet complete, the class fails with an error.
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

ANSI (Cross Platform) int64 GetTotalSize(); Unicode (Windows) LONG64 GetTotalSize();
int64 ipworks_pop_gettotalsize(void* lpObj);
qint64 GetTotalSize();
Default Value
0
Remarks
This property contains the cumulative size in bytes of messages in the mailbox (including headers). When the class is not connected to the server, the value of this property is 0. When connected, it contains the cumulative size of all the messages in the mail box as reported by the POP server.
This property is read-only.
Data Type
Long64
User Property (POP Class)
This property includes the user identifier for the mailbox.
Syntax
ANSI (Cross Platform) char* GetUser();
int SetUser(const char* lpszUser); Unicode (Windows) LPWSTR GetUser();
INT SetUser(LPCWSTR lpszUser);
char* ipworks_pop_getuser(void* lpObj);
int ipworks_pop_setuser(void* lpObj, const char* lpszUser);
QString GetUser();
int SetUser(QString qsUser);
Default Value
""
Remarks
This property contains the user identifier for the mailbox. This property must be set before the class connects to the MailServer.
Data Type
String
Config Method (POP Class)
Sets or retrieves a configuration setting.
Syntax
ANSI (Cross Platform) char* Config(const char* lpszConfigurationString); Unicode (Windows) LPWSTR Config(LPCWSTR lpszConfigurationString);
char* ipworks_pop_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

This method returns the size in bytes of the current message.
Syntax
ANSI (Cross Platform) int64 QueryMessageSize(); Unicode (Windows) LONG64 QueryMessageSize();
int64 ipworks_pop_querymessagesize(void* lpObj);
qint64 QueryMessageSize();
Remarks
This method queries the server for the size in bytes of the message specified by MessageNumber. The method returns the size (in bytes) of the message.
If the class is not connected, or MessageNumber does not contain a valid message number, the return value is 0. Otherwise, it returns the size of the mail message (including headers) as reported by the server.
The MailServer is asked about the size of the message only if the MessageNumber property has changed. If MessageNumber has not changed, the class returns a cached value.
Error Handling (C++)
This method returns a Long64 value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

int ipworks_pop_setmessagestream(void* lpObj, IPWorksStream* sMessageStream);
int SetMessageStream(IPWorksStream* sMessageStream);
Remarks
This method sets the stream to which the message downloaded from the server will be written. If a download stream is set before the Retrieve method is called, the downloaded data will be written to the stream. The stream should be open and normally set to position 0. The class will automatically close this stream if CloseStreamAfterTransfer is set to True (default). If the stream is closed, you will need to call SetMessageStream again before calling Retrieve again. The downloaded content will be written starting at the current position in the stream.
Note: SetMessageStream and LocalFile will reset the other.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

// To handle, connect one or more slots to this signal. void ConnectionStatus(POPConnectionStatusEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FireConnectionStatus(POPConnectionStatusEventParams *e) {...}
Remarks
The ConnectionStatus 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. | |

// To handle, connect one or more slots to this signal. void Error(POPErrorEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FireError(POPErrorEventParams *e) {...}
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the class 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.
Header Event (POP Class)
This event is fired for every message header being retrieved.
Syntax
ANSI (Cross Platform) virtual int FireHeader(POPHeaderEventParams *e);
typedef struct {
const char *Field;

INT MessageSize; INT reserved; } POPMessageListEventParams;
#define EID_POP_MESSAGELIST 5 virtual INT IPWORKS_CALL FireMessageList(INT &iMessageNumber, LPSTR &lpszMessageUID, INT &iMessageSize);
class POPMessageListEventParams { public: int MessageNumber(); const QString &MessageUID(); int MessageSize(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void MessageList(POPMessageListEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FireMessageList(POPMessageListEventParams *e) {...}
Remarks
When ListMessageSizes is called, MessageSize is valid, and MessageUID is always an empty string.
When ListMessageUIDs is called, MessageUID is valid, and MessageSize is 0.
PITrail Event (POP Class)
Traces the commands sent to the mail server, and the respective replies.
Syntax
ANSI (Cross Platform) virtual int FirePITrail(POPPITrailEventParams *e);
typedef struct {
int Direction;
const char *Message; int reserved; } POPPITrailEventParams;
Unicode (Windows) virtual INT FirePITrail(POPPITrailEventParams *e);
typedef struct {
INT Direction;
LPCWSTR Message; INT reserved; } POPPITrailEventParams;
#define EID_POP_PITRAIL 6 virtual INT IPWORKS_CALL FirePITrail(INT &iDirection, LPSTR &lpszMessage);
class POPPITrailEventParams { public: int Direction(); const QString &Message(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void PITrail(POPPITrailEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FirePITrail(POPPITrailEventParams *e) {...}
Remarks
The PITrail event is useful for debugging purposes. It shows all 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 class code). |
SSLServerAuthentication Event (POP Class)
Fired after the server presents its certificate to the client.
Syntax
ANSI (Cross Platform) virtual int FireSSLServerAuthentication(POPSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;
const char *Status;
int Accept; int reserved; } POPSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(POPSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;
LPCWSTR Status;
BOOL Accept; INT reserved; } POPSSLServerAuthenticationEventParams;
#define EID_POP_SSLSERVERAUTHENTICATION 7 virtual INT IPWORKS_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);
class POPSSLServerAuthenticationEventParams { public: const QByteArray &CertEncoded(); const QString &CertSubject(); const QString &CertIssuer(); const QString &Status(); bool Accept(); void SetAccept(bool bAccept); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void SSLServerAuthentication(POPSSLServerAuthenticationEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FireSSLServerAuthentication(POPSSLServerAuthenticationEventParams *e) {...}
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (POP Class)
Fired when secure connection progress messages are available.
Syntax
ANSI (Cross Platform) virtual int FireSSLStatus(POPSSLStatusEventParams *e);
typedef struct {
const char *Message; int reserved; } POPSSLStatusEventParams;
Unicode (Windows) virtual INT FireSSLStatus(POPSSLStatusEventParams *e);
typedef struct {

#define EID_POP_SSLSTATUS 8 virtual INT IPWORKS_CALL FireSSLStatus(LPSTR &lpszMessage);
class POPSSLStatusEventParams { public: const QString &Message(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void SSLStatus(POPSSLStatusEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FireSSLStatus(POPSSLStatusEventParams *e) {...}
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
StartTransfer Event (POP Class)
This event is fired when the message starts transferring.
Syntax
ANSI (Cross Platform) virtual int FireStartTransfer(POPStartTransferEventParams *e);
typedef struct {
int Direction; int reserved; } POPStartTransferEventParams;
Unicode (Windows) virtual INT FireStartTransfer(POPStartTransferEventParams *e);
typedef struct {
INT Direction; INT reserved; } POPStartTransferEventParams;
#define EID_POP_STARTTRANSFER 9 virtual INT IPWORKS_CALL FireStartTransfer(INT &iDirection);
class POPStartTransferEventParams { public: int Direction(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void StartTransfer(POPStartTransferEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FireStartTransfer(POPStartTransferEventParams *e) {...}
Remarks
The StartTransfer event is fired when the message body starts transferring from the server to the local host.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Transfer Event (POP Class)
This event is fired when the message is transferred from MailServer .
Syntax
ANSI (Cross Platform) virtual int FireTransfer(POPTransferEventParams *e);
typedef struct {
int Direction;
int64 BytesTransferred;
int PercentDone;
const char *Text; int lenText;
int EOL; int reserved; } POPTransferEventParams;
Unicode (Windows) virtual INT FireTransfer(POPTransferEventParams *e);
typedef struct {
INT Direction;
LONG64 BytesTransferred;
INT PercentDone;
LPCSTR Text; INT lenText;
BOOL EOL; INT reserved; } POPTransferEventParams;
#define EID_POP_TRANSFER 10 virtual INT IPWORKS_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText, BOOL &bEOL);
class POPTransferEventParams { public: int Direction(); qint64 BytesTransferred(); int PercentDone(); const QByteArray &Text(); bool EOL(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Transfer(POPTransferEventParams *e);
// Or, subclass POP and override this emitter function. virtual int FireTransfer(POPTransferEventParams *e) {...}
Remarks
The Text parameter contains the portion of the message data to be retrieved.
The BytesTransferred parameter contains the number of bytes transferred since the beginning of the message, including header bytes. At the end of transmission (i.e., when the last Transfer event is fired), BytesTransferred equals the value of the MessageSize property.
The Transfer event is fired for every line of the message. For complete lines, there is no terminating newline at the end of the Text parameter, and EOL is True. The EOL parameter is False when a line is broken (usually for being too long).
A faster way to retrieve a message is to assign a value to the LocalFile property and use the Transfer event to check the progress rather than to get the actual data.
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.
Note: For the PercentDone parameter value to be correct, the GetMessageSize configuration setting must be set to True.
IPWorksStream Type

Methods | |
Close |
Closes the stream, releasing all resources currently allocated for it.
void Close() {} This method is called automatically when an IPWorksStream object is deleted. |
Flush |
Forces all data held by the stream's buffers to be written out to storage.
int Flush() { return 0; } Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0. |
Read |
Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.
int Read(void* buffer, int count) = 0; Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed. |
Seek |
Sets the current position within the stream based on a particular point of origin.
int64 Seek(int64 offset, int seekOrigin) = 0; Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:
Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported. |
Write |
Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.
int Write(const void* buffer, int count) = 0; Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed. |
Config Settings (POP Class)
The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.POP 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.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for 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.

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 class will reuse the context if and only if the following criteria are met:
- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the class is the same.
The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.
The default value is:
/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
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 class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.

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 class 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 class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This 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 class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.
Note: This setting is only applicable when SSLProvider is set to Internal.

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 class 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 class fails with an error.
The format of this value is a comma separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this 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:
