PIMAP Class
Properties Methods Events Config Settings Errors
The PIMAP class is used to communicate with IMAP servers to retrieve and process OpenPGP encrypted and/or signed messages and any attachments.
Syntax
ipworksopenpgp.PIMAP
Remarks
The PIMAP class offers an easy-to-use interface: it implements a standard IMAP client, as specified in RFC 1730 and RFC 2060, and supports decrypting and verifying signatures of encrypted and signed emails using OpenPGP. Additionally, it enables you to create messages bound for multiple recipients with different keys, simultaneously encrypt and compress with the most popular compression algorithms, and control other aspects such as the encrypting algorithm to use.
Connect to a Mail Server
The first step in using the class is specifying a MailServer, a User to connect as, and a Password to authenticate with. After that, one or more requests may be sent to the server via the class's methods. Results are retrieved through events and a number of key properties.
Examine a Mailbox
Normally, after connecting to the server a Mailbox is selected (or examined) using the ExamineMailbox method. After the Mailbox is selected, MessageCount and RecentMessageCount show the number of messages in the mailbox, and MailboxFlags shows the flags pertaining to the mailbox.
A number of operations may be performed by the server in response to commands sent via the class's methods. The primary arguments for most commands are the Mailbox property and the MessageSet property. The MessageSet property denotes either a single message or a range of messages. Other arguments are specified through other properties such as SortCriteria, MessageFlags, etc.
Responses are received through events such as MessageInfo and MailboxList, and are also reflected in properties such as MessageText, MessageSubject, etc.
Decrypt
To process an encrypted or signed message, first retrieve the message text and headers by calling RetrieveMessageHeaders and RetrieveMessageText.
To decrypt a message specify the private key to be used for decryption by adding a key to Keys. For instance:
pimap.Keys.Add(new Key("c:\\my_keyring_dir", "recipient@nsoftware.com"));
pimap.Keys[0].Passphrase = "password";
The specified private key will be used to decrypt the message when calling Decrypt.
Verify
To verify the signature of a message specify the public key to be used for signature verification by
adding a key to SignerKeys. For instance:
pimap.Keys.Add(new Key("c:\\my_keyring_dir", "sender@nsoftware.com"));
The specified public key will be used to verify the signature when calling VerifySignature. To
decrypt and verify in one step call DecryptAndVerifySignature.
Retrieve MIME Message Parts
The MessagePart event describes the MIME structure of retrieved messages. One MessagePart event is fired for every message part, giving information about the particular part. Later on, message parts may be retrieved separately through the RetrieveMessagePart method. This speeds up processing by avoiding the need to retrieve full messages from the server.
Trace Client and Server Communication
The PITrail event traces the interaction between the client and the server. It includes all exchanges except for transfers of messages, message parts, and message headers.

This property is not available at design time.
SSLProvider Property (PIMAP Class)
This property specifies the Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.
Syntax
public int getSSLProvider(); public void setSSLProvider(int SSLProvider); Enumerated values: public final static int sslpAutomatic = 0; public final static int sslpPlatform = 1; public final static int sslpInternal = 2;
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are as follows:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

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 will 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. |
StartByte Property (PIMAP Class)
This property includes the byte index of the position where the transfer should start.
Syntax
public long getStartByte(); public void setStartByte(long startByte);
Default Value
0
Remarks
StartByte and EndByte are used together with the RetrieveMessagePart method to specify the portion of the message to be retrieved from the server.
When StartByte or EndByte contain values other than the default (0), only the corresponding portion of the message is retrieved from the server.
Byte indexes start from 1. The default value for EndByte is 0, which corresponds to the end of the message.
This property is not available at design time.
Timeout Property (PIMAP Class)
This property includes the timeout for the class.
Syntax
public int getTimeout(); public void setTimeout(int timeout);
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 throws an exception.
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.
UIDMode Property (PIMAP Class)
If True, this property indicates whether permanent message identifiers are used instead of the default temporary identifiers.
Syntax
public boolean isUIDMode(); public void setUIDMode(boolean UIDMode);
Default Value
False
Remarks
This property indicates if a permanent identifier should be used. Normally, the IMAP server uses temporary message identifiers that are valid only during the current session. If UIDMode is True, permanent message identifiers are used instead.
The following IMAP protocol operations use the UID mode: COPY, FETCH, STORE, and SEARCH.
This property is not available at design time.
UIDValidity Property (PIMAP Class)
This property includes the UIDValidity parameter sent from the server in response to SelectMailbox command.
Syntax
public String getUIDValidity();
Default Value
""
Remarks
Every time a mailbox is selected, a UIDValidity is returned from the server. Most of the time, this value will not change from call to call. If it does change, this means that all previously returned UIDs for messages inside this mailbox are now invalid.
This property is read-only and not available at design time.
User Property (PIMAP Class)
This property includes the username used to authenticate to the MailServer .
Syntax
public String getUser(); public void setUser(String user);
Default Value
""
Remarks

Config Method (PIMAP Class)
Sets or retrieves a configuration setting.
Syntax
public String config(String configurationString);
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.

Remarks
This method attempts to both decrypt and verify the signature of the message. All of the properties affected by calling the Decrypt and VerifySignature methods are affected in the same manner.
This method may be used when the data is signed, encrypted, or signed and encrypted. For instance, if the data is encrypted but not signed you may still use this method and the class will perform the decryption without error.
The message will be decrypted using the keys specified in Keys. Before decryption begins the class will fire the RecipientInfo event with information about the encrypted message, including the key used to encrypt the message. Within this event you may use the available information to load the correct key into Keys.
The message will be verified using the keys specified in SignerKeys. Before verification begins the class will fire the SignatureInfo event with information about the signature including the key used to sign the message. Within this event you may use the information available to load the correct key into SignerKeys.
By default, if the signature is not valid the class throws an exception. The configuration setting RequireValidSignature may be set to False to disable this requirement. When RequireValidSignature is set to False, the Status parameter of the VerificationStatus event should be checked to determine the result of the operation.
NOTE: This method does not attempt to check the validity of the signing key itself.

After calling this method, check the LastReply property or monitor the PITrail event to obtain the server's response.
SetMailboxACL Method (PIMAP Class)
This method sets mailbox access control rights for a specific user.
Syntax
public void setMailboxACL(String user, String rights);
Remarks
This method changes the access control list for the mailbox specified in the Mailbox property so that User is granted the permissions specified in Rights.
Rights is a string containing an optional plus ("+") or minus ("-") prefix, followed by zero or more rights characters. If the string starts with a plus, the rights are added to any existing rights for the identifier. If the string starts with a minus, the rights are removed from any existing rights for the identifier. If the string does not start with a plus or minus, the rights replace any existing rights for the identifier.
Standard rights include the following:
l | Lookup (Visible to be listed) |
r | Read (Can be selected, retrieved, searched, and copied) |
s | Keep (Seen/unseen information across sessions) |
w | Write (Stores flags other than SEEN and DELETED) |
i | Insert (Can be appended and copied into) |
p | Post (Can send mail to submission address for mailbox) |

Syntax
public void setMessageStream(java.io.OutputStream messageStream);
Remarks
This method sets the stream to which the message (or message part) downloaded from the server will be written. If a download stream is set before the RetrieveMessageText or RetrieveMessagePart methods are 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 True (default). If the stream is closed, you will need to call SetMessageStream again before calling RetrieveMessageText or RetrieveMessagePart. The downloaded content will be written starting at the current position in the stream.
Note: SetMessageStream and LocalFile will reset the other.
StartIdle Method (PIMAP Class)

VerifySignature Method (PIMAP Class)
Verifies the signature of the current message.
Syntax
public void verifySignature();
Remarks
This method verifies the signature of the message.
The message will be verified using the keys specified in SignerKeys. Before verification begins the class will fire the SignatureInfo event with information about the signature including the key used to sign the message. Within this event you may use the information available to load the correct key into SignerKeys.
By default, if the signature is not valid the class throws an exception. The configuration setting RequireValidSignature may be set to False to disable this requirement. When RequireValidSignature is set to False, the Status parameter of the VerificationStatus event should be checked to determine the result of the operation.
ConnectionStatus Event (PIMAP Class)

KeyId is the hex-encoded, 4-byte or 8-byte Id of the key the passphrase is required for. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:
5E70662EA810E768
Fingerprint holds the hex-encoded, 20-byte fingerprint of the key the passphrase is required for. This is in the form:
5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

Remarks
This event fires when the VerifySignature or DecryptAndVerifySignature method is called. It provides information about the signature of the message.
KeyId is the hex-encoded 4- or 8-byte Id of the key used to sign the message. If a subkey was used to sign the message this will be the Id of that subkey. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:
5E70662EA810E768
Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:
5E70662EA810E768391A2FE8F7B7D49C89C9D7B1
The KeyId and Fingerprint parameters can be used to identify the correct key to specify in SignerKeys. SignerKeys can be set from within this event as this event fires directly before the verification process begins.
It is recommended to use the Fingerprint to identify the correct key, as it is possible for different keys to have the same KeyId.
SigningAlgorithm describes the hash algorithm used when the message was originally signed. This value is applicable only to the message signature, not the key used to sign the message. Possible values are:
- SHA1
- MD5
- SHA256
- SHA384
- SHA512
- SHA224
- RIPEMD160
- SHA3-256
- SHA3-512

SSLServerAuthentication Event (PIMAP Class)
Fired after the server presents its certificate to the client.
Syntax
public class DefaultPIMAPEventListener implements PIMAPEventListener { ... public void SSLServerAuthentication(PIMAPSSLServerAuthenticationEvent e) {} ... } public class PIMAPSSLServerAuthenticationEvent { public byte[] certEncoded; public String certSubject; public String certIssuer; public String status; public boolean accept; //read-write }
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 (PIMAP Class)
Fired when secure connection progress messages are available.
Syntax
public class DefaultPIMAPEventListener implements PIMAPEventListener { ... public void SSLStatus(PIMAPSSLStatusEvent e) {} ... } public class PIMAPSSLStatusEvent { public String message; }
Remarks

Syntax
public class DefaultPIMAPEventListener implements PIMAPEventListener { ... public void startTransfer(PIMAPStartTransferEvent e) {} ... } public class PIMAPStartTransferEvent { public int direction; }
Remarks
The StartTransfer event is fired when the message body or the part data start transferring from the server to the local host. Further progress information is provided by the Transfer and EndTransfer events.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Status Event (PIMAP Class)
Shows the progress of the operation.
Syntax
public class DefaultPIMAPEventListener implements PIMAPEventListener { ... public void status(PIMAPStatusEvent e) {} ... } public class PIMAPStatusEvent { public String message; }
Remarks
The event is fired for informational and logging purposes only. It may be used to track the progress of an operation.
The level of detail is controlled by the LogLevel setting.
Transfer Event (PIMAP Class)
This event is fired while the message is transferred from the MailServer .
Syntax
public class DefaultPIMAPEventListener implements PIMAPEventListener { ... public void transfer(PIMAPTransferEvent e) {} ... } public class PIMAPTransferEvent { public int direction; public long bytesTransferred; public int percentDone; public String text; }
Remarks
The Transfer event is fired for every incoming line when receiving a message or part data from the MailServer
The Text parameter contains the portion of the message or the part data being 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. There is no terminating newline at the end of the Text parameter. 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 only 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.

Remarks
This event fires when VerifySignature or DecryptAndVerifySignature is called. It provides information about the result.
KeyId is the hex-encoded 4- or 8-byte Id of the key used to sign the message. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:
5E70662EA810E768
Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:
5E70662EA810E768391A2FE8F7B7D49C89C9D7B1
Status holds the result of the operation. Possible values are:
0 | Verification succeeded |
1 | Verification failed |
2 | The required key could not be found |
3 | Verification succeeded but the key is expired. |

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).
StoreB
byte[]
Default Value: "MY"
This is the name of the certificate store for the client certificate.
The StoreType field denotes the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.
Store is used in conjunction with the Subject field to specify client certificates. If Store has a value, and Subject or Encoded is set, a search for a certificate is initiated. Please see the Subject field for details.
Designations of certificate stores are platform dependent.
The following designations are the most common User and Machine certificate stores in Windows:
MY | A certificate store holding personal certificates with their associated private keys. |
CA | Certifying authority certificates. |
ROOT | Root certificates. |
In Java, the certificate store normally is a file containing certificates and optional private keys.

Config Settings (PIMAP 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.PIMAP Config Settings
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data is logged. |
3 (Debug) | Debug data is logged. |
This config is True by default, and must be true when verifying an OpenPGP v6 cleartext signature. When enabled, the cleartext portion will be cached in memory until the signature is fully processed.
Note: If the signature is known to be an OpenPGP v4 cleartext signature beforehand (i.e., signed with a v4 key), this config may be set to False. However, if this config is disabled, the class will be unable to verify OpenPGP v6 cleartext signatures. In this case, the class will throw an exception when calling VerifySignature or DecryptAndVerifySignature.
This setting will be populated after calling Decrypt, VerifySignature, or DecryptAndVerifySignature.

The default value for this setting is False.
The date-time should be formatted according to the IMAP RFC specifications. For example, "22-Jan-2013 12:34:56 -0500" indicates January 22nd, 2013, at 12:34:56 PM EST.
By default, if this setting is not specified, no date-time is sent with the APPEND request, and the server will use the current time.
Bearer ya29.AHES6ZRmS-8xPbpGetC1VbABJIBRdKm-c4X7wMVGAbgxdGt5q8Ts3Q
Note: When using amXOAUTH2, User must be specified, but Password is not required.
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.

This configuration setting specifies whether the class will use the IMAP4 Id extension defined in RFC 2971 and send the Id command to the server. When set to true, the class will send the Id command with the value IPWorksIMAP if the server supports this as defined in the server's response to the CAPABILITY command.
The default value is false, and this command will not be sent.
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 classs that do not directly expose Firewall properties.
If this entry is set, the class acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.
RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.
The connection to the firewall is made by calling the Connect method.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
Note: This configuration setting is provided for use by classs 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 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 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 multihomed 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 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.

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.
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.

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

By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the 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.
Note: This value must be set after SSLProvider is set.
Example values:
obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA");

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 class 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 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 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.
Note: When SSLProvider is set to Internal this value is automatically set to true. This is needed for proper validation when using the internal provider.
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 traffic for debugging purposes. When writing to this file, the class 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:
server.Config("SSLNegotiatedCipherStrength[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

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 ...

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

Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
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.

Base Config Settings
In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

The Java edition requires installation of the FIPS-certified Bouncy Castle library regardless of the target operating system. This can be downloaded from https://www.bouncycastle.org/fips-java/. Only the "Provider" library is needed. The jar file should then be installed in a JRE search path.
The following classes must be imported in the application in which the component will be used:
import java.security.Security;
import org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider;
The Bouncy Castle provider must be added as a valid provider and must also be configured to operate in FIPS mode:
System.setProperty("org.bouncycastle.fips.approved_only","true");
Security.addProvider(new BouncyCastleFipsProvider());
When UseFIPSCompliantAPI is true, Secure Sockets Layer (SSL)-enabled classes can optionally be configured to use the Transport Layer Security (TLS) Bouncy Castle library. When SSLProvider is set to sslpAutomatic (default) or sslpInternal, an internal TLS implementation is used, but all cryptographic operations are offloaded to the Bouncy Castle FIPS provider to achieve FIPS-compliant operation. If SSLProvider is set to sslpPlatform, the Bouncy Castle JSSE will be used in place of the internal TLS implementation.
To enable the use of the Bouncy Castle JSSE take the following steps in addition to the steps above. Both the Bouncy Castle FIPS provider and the Bouncy Castle JSSE must be configured to use the Bouncy Castle TLS library in FIPS mode. Obtain the Bouncy Castle TLS library from https://www.bouncycastle.org/fips-java/. The jar file should then be installed in a JRE search path.
The following classes must be imported in the application in which the component will be used:
import java.security.Security;
import org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider;
//required to use BCJSSE when SSLProvider is set to sslpPlatform
import org.bouncycastle.jsse.provider.BouncyCastleJsseProvider;
The Bouncy Castle provider must be added as a valid provider and also must be configured to operate in FIPS mode:
System.setProperty("org.bouncycastle.fips.approved_only","true");
Security.addProvider(new BouncyCastleFipsProvider());
//required to use BCJSSE when SSLProvider is set to sslpPlatform
Security.addProvider(new BouncyCastleJsseProvider("fips:BCFIPS"));
//optional - configure logging level of BCJSSE
Logger.getLogger("org.bouncycastle.jsse").setLevel(java.util.logging.Level.OFF);
//configure the class to use BCJSSE
component.setSSLProvider(1); //platform
component.config("UseFIPSCompliantAPI=true");
Note: TLS 1.3 support requires the Bouncy Castle TLS library version 1.0.14 or later.
FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.
For more details, please see the FIPS 140-2 Compliance article.
Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.
Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.
This setting is set to false by default on all platforms.
