SPOP Class
Properties Methods Events Config Settings Errors
The SPOP Class is used to easily retrieve electronic mail from internet post office servers (POP).
Syntax
SPOP
Remarks
The SPOP Class is the S/MIME-enabled equivalent of the IPWorks POP Class. In addition to standard POP functions, the SPOP class can decrypt and verify message signatures. The methods and properties for decrypting and verifying signatures are identical to those provided with the S/MIME Class. When attempting to verify a signed message or when decrypting a message call, the Decrypt, VerifySignature, or DecryptAndVerifySignature methods and the resulting text will be replaced in Message.
The SPOP 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).

int GetSSLStartMode();
int SetSSLStartMode(int iSSLStartMode);
Default Value
3
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 class 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 class will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS. |
3 (sslNone - default) | No SSL negotiation, no SSL security. All communication will be in plaintext mode. |
Data Type
Integer
Timeout Property (SPOP Class)
A timeout for the class.
Syntax
ANSI (Cross Platform) int GetTimeout();

int ipworkssmime_spop_gettimeout(void* lpObj);
int ipworkssmime_spop_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.

char* ipworkssmime_spop_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.

Unicode (Windows) virtual INT FirePITrail(SPOPPITrailEventParams *e);
typedef struct {
INT Direction;
LPCWSTR Message; INT reserved; } SPOPPITrailEventParams;
#define EID_SPOP_PITRAIL 6 virtual INT IPWORKSSMIME_CALL FirePITrail(INT &iDirection, LPSTR &lpszMessage);
class SPOPPITrailEventParams { public: int Direction(); const QString &Message(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void PITrail(SPOPPITrailEventParams *e);
// Or, subclass SPOP and override this emitter function. virtual int FirePITrail(SPOPPITrailEventParams *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. |

SSLServerAuthentication Event (SPOP Class)
Fired after the server presents its certificate to the client.
Syntax
ANSI (Cross Platform) virtual int FireSSLServerAuthentication(SPOPSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;
const char *Status;
int Accept; int reserved; } SPOPSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(SPOPSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;

// To handle, connect one or more slots to this signal. void SSLServerAuthentication(SPOPSSLServerAuthenticationEventParams *e);
// Or, subclass SPOP and override this emitter function. virtual int FireSSLServerAuthentication(SPOPSSLServerAuthenticationEventParams *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 (SPOP Class)

// To handle, connect one or more slots to this signal. void StartTransfer(SPOPStartTransferEventParams *e);
// Or, subclass SPOP and override this emitter function. virtual int FireStartTransfer(SPOPStartTransferEventParams *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 (SPOP Class)
This event is fired when the message is transferred from MailServer .
Syntax
ANSI (Cross Platform) virtual int FireTransfer(SPOPTransferEventParams *e);
typedef struct {
int Direction;
int64 BytesTransferred;
int PercentDone;
const char *Text; int lenText;
int EOL; int reserved; } SPOPTransferEventParams;
Unicode (Windows) virtual INT FireTransfer(SPOPTransferEventParams *e);
typedef struct {
INT Direction;
LONG64 BytesTransferred;
INT PercentDone;
LPCSTR Text; INT lenText;
BOOL EOL; INT reserved; } SPOPTransferEventParams;
#define EID_SPOP_TRANSFER 10 virtual INT IPWORKSSMIME_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText, BOOL &bEOL);
class SPOPTransferEventParams { 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(SPOPTransferEventParams *e);
// Or, subclass SPOP and override this emitter function. virtual int FireTransfer(SPOPTransferEventParams *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.
IPWorksSMIMEStream Type
Syntax
IPWorksSMIMEStream (declared in ipworkssmime.h)
Remarks
The SPOP class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the IPWorksSMIMEStream interface and pass the SPOP class an instance of that concrete class.
When implementing the IPWorksSMIMEStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.
Config Settings (SPOP 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
When AuthMechanism is set to amSASLPlain or amSASLDigestMD5, this configuration setting may specify an authorization identity to be used when authenticating.
Subjects that have been Quoted-Printable or Base64 encoded are automatically decoded when this configuration setting is True (default). Only subjects in the format "=?iso-8859-1?Q?data?=" will be correctly decoded.
By default, this value is False. When set to True, the class will retrieve the message size from the server before downloading it and the PercentDone parameter of the Transfer event will be populated. When this value is False (default), the PercentDone parameter of the Transfer event will not be updated and will evaluate to -1.
Normally, internet mail message lines are up to 80 bytes long; however, different mail systems might use other values. Change the value of this property if you are expecting longer lines.
TCPClient Config Settings
When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.
This configuration setting is provided for use by classs that do not directly expose Firewall properties.
If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
The FirewallPort is set automatically when FirewallType is set to a valid value.
Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.
The appropriate values are as follows:
0 | No firewall (default setting). |
1 | Connect through a tunneling proxy. FirewallPort is set to 80. |
2 | Connect through a SOCKS4 Proxy. FirewallPort is set to 1080. |
3 | Connect through a SOCKS5 Proxy. FirewallPort is set to 1080. |
10 | Connect through a SOCKS4A Proxy. FirewallPort is set to 1080. |
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class fails with an error.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.
Note: This value is not applicable in macOS.
When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the number of times that the keep-alive packets will be sent before the remote host is considered disconnected. The system default if this value is not specified here is 9.
Note: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.
When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.
This property controls how a connection is closed. The default is True.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.
The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In 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).
This must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; 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.
MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.
This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.
This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:
www.google.com;www.nsoftware.com
If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.
Note: This value is not applicable in Java.
When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.
By default, this config is set to false.
When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:
0 | IPv4 Only |
1 | IPv6 Only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this setting has no effect if SSLProvider is set to Platform.
This functionality is available only when the provider is OpenSSL.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 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.
This functionality is available only when the provider is OpenSSL.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by
-----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.
This functionality is available only when the provider is OpenSSL.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
This functionality is available only when the provider is OpenSSL.
By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
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.
This setting specifies the paths on disk to CA certificate files on Unix/Linux.
The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.
The default value is:
/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem
This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. 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-----
This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.
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.
The enabled cipher suites to be used in SSL negotiation.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.
Example values when SSLProvider is set to Platform:
obj.config("SSLEnabledCipherSuites=*");

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Used to enable/disable the supported security protocols.
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 specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.
This setting is only applicable when SSLProvider is set to Internal.
This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.
If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.
When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS 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.
Returns the cipher suite negotiated during the SSL handshake.
Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");
Returns the strength of the cipher suite negotiated during the SSL handshake.
Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipherStrength[connId]");
Returns the cipher suite negotiated during the SSL handshake represented as a single string.
Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipherSuite[connId]");
Returns the key exchange algorithm negotiated during the SSL handshake.
Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedKeyExchange[connId]");
Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.
Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedKeyExchangeStrength[connId]");
Returns the protocol version negotiated during the SSL handshake.
Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedVersion[connId]");
The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:
0x00000001 | Ignore time validity status of certificate. |
0x00000002 | Ignore time validity status of CTL. |
0x00000004 | Ignore non-nested certificate times. |
0x00000010 | Allow unknown Certificate Authority. |
0x00000020 | Ignore wrong certificate usage. |
0x00000100 | Ignore unknown certificate revocation status. |
0x00000200 | Ignore unknown CTL signer revocation status. |
0x00000400 | Ignore unknown Certificate Authority revocation status. |
0x00000800 | Ignore unknown Root revocation status. |
0x00008000 | Allow test Root certificate. |
0x00004000 | Trust test Root certificate. |
0x80000000 | Ignore non-matching CN (certificate CN not-matching server name). |
This functionality is currently not available when the provider is OpenSSL.
This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.
The value of this 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-----
This setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.
When specified the class will verify that the server certificate signature algorithm is among the values specified in this 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.
This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:

- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1"
- "ffdhe_2048" (default)
- "ffdhe_3072" (default)
- "ffdhe_4096"
- "ffdhe_6144"
- "ffdhe_8192"
This setting holds a comma separated list of allowed signature algorithms. Possible values are:

Socket Config Settings
If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.
Note: This option is not valid for UDP ports.
When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).
This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:
- Product: The product the license is for.
- Product Key: The key the license was generated from.
- License Source: Where the license was found (e.g., RuntimeLicense, License File).
- License Type: The type of license installed (e.g., Royalty Free, Single Server).
- Last Valid Build: The last valid build number for which the license will work.
In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.
This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.
If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.
If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.
When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.
Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.
On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.
To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
Trappable Errors (SPOP Class)
Error Handling (C++)
Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
