SMIMEEmail Task

The SMIMEEmail Component adds S/MIME-protected email capability to the SSIS Package.

Remarks

The SMIMEEmail Task adds support for sending and receiving S/MIME-protected emails to BizTalk Server. The task allows you to encrypt and sign emails before sending and decrypt and verify signatures on received emails.

SMIMEEmail Receiver Task

The SMIMEEmail Receiver task is the S/MIME enabled equivalent of the Email Receive task. In addition to standard IMAP and POP3 functions, the SMIMEEmail Receiver task can decrypt and/or verify message signatures. In order to use the SMIMEEmail Receiver task, you must first select a ServerType. You must also enter a MailServer and User. For servers that require authentication, you will also have to enter a Password. To activate SSL, you must also set the SSLAcceptServerCert and SSLStartMode. The adapter will attempt to determine the correct port to connect to based on the server type and SSL settings. However, you may override the default by directly setting the MailPort in the property pages.

Once you have your port set up, the task will connect to the server once every PollingInterval and download messages. To control how the messages are downloaded, or to prevent duplicate messages from being fetched from the mail server, you may set the DeleteMode to an appropriate value. For IMAP connections, you may also set a Filter.

The task will populate the MessageList property with the information retrieved from the downloaded emails.

When it receives an email, the SMIMEEmail Reciever task will detect if the message is encrypted and attempt to decrypt it using the certificate in the Certificate property. If the message is signed, it will also attempt to verify the signature using the certificate in the SignerCert property.

SMIMEEmail Sender Task

The SMIMEEmail Sender Task is a complete SMTP client that can also encrypt and sign emails. To send emails from the task you must set at a minimum your SMTPServer, as well as your From and SendTo email addresses. Should you need to guarantee a secure transmission, you may set the SSLCert and SSLStartMode properties, as well as a specific SSLAcceptServerCert.

You may also add carbon copy and blind carbon copy recipients via the Cc and BCc properties. If you wish to receive delivery or read notifications, you can set the DeliveryReceipt and ReadReceipt properties. You may set the Subject of your message. The contents of the outbound message will be sent as the body of the email.

If you want to encrypt an email you are sending, set the RecipientCert property to the receiver's certificate, set the EncryptData property to true, and set EncryptingAlgorithm to the encryption algorithm you want to use. To sign an email, set the Certificate property to your certificate, set the SignData property to true, and set the SigningAlgorithm property to the hash algorithm you want to use for signing.

The DuplicateAttachmentAction will determine what happens if a file with the same name already exists.

This property is not available in the Sender.

Attachments Property (SMIMEEmail Task)

Specifies which files the component should include as attachments in the outgoing message.

Data Type

String

Default Value

Remarks

Attachments may be used when sending an email to specify which files will be included as attachments to the outgoing message.

The value should be a pipe ("|") -delimited sequence of one or more filenames. The filenames should be specified with paths if necessary, so that the files may be found on the local file system.

If this property is set to an empty string, no attachments will be included in the outgoing message.

This property is not available in the Receiver.

This property is not available in the Sender.

SigningAlgorithm Property (SMIMEEmail Task)

Textual description of the signature hash algorithm.

Data Type

String

Default Value

"SHA256"

Remarks

This property specifies the hash algorithm used to prepare the message digest for signature.

This property must contain either the name of the algorithm (such as "MD5" or "SHA1"), or an object id (OID) string representing the hash algorithm. Possible values are:

sha1
md5
sha-256 (default)
sha-384
sha-512
sha-224

When read, the value of the property always contains the OID of the algorithm, or an empty string if the algorithm is unknown.

This property is not available in the Receiver.

SMTPMessageId Property (SMIMEEmail Task)

The id of the mail message (optional).

Data Type

String

Default Value

Remarks

This property is used to specify the value of the SMTP MessageId header in the outgoing message. When this property is not set, the task will automatically calculate the MessageId. It is recommended that this property be left blank to allow the task to automatically create the MessageId value unless there is a specific need to define this value.

This property is not available in the Receiver.

SMTPPort Property (SMIMEEmail Task)

The server port for SMTP (default 25).

Data Type

Integer

Default Value

Remarks

A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is established by the task

For implicit SSL, use port 465 (please refer to the SSLStartMode property for more information).

This property is not available in the Receiver.

SMTPServer Property (SMIMEEmail Task)

The name or address of a mail server (mail relay).

Data Type

String

Default Value

Remarks

The SMTPServer property specifies the IP address (IP number in dotted internet format) or Domain Name for a mail relay through which messages will be routed.

The current version of the task does not provide a default value for the mail relay. You must provide a host name yourself. Generally, any internet host with an SMTP server will suffice (a UNIX host for example), but it is preferable to select an SMTPServer that is close to the machine sending mail.

This property is not available in the Receiver.

SSLAcceptServerCert Property (SMIMEEmail Task)

Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.

Data Type

Certificate

Remarks

If it finds any issues with the certificate presented by the server, the task will normally terminate the connection with an error. You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

This property is used to set a Public Key Certificate.

Ordinarily, the system will attempt to locate the public key in trusted certificate stores in the system registry. If a match is found, the certificate is trusted, and the process proceeds without error. If the certificate is not trusted, the task will report an error.

You may explicitly set a public key, either to accept a key that is not installed on the system, or to ensure that a specific key is presented. Public key certificates may be loaded from the machine registry or from file. If you click on the ellipses, a certificate selection dialog will open. To select a public key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of available certificates will be shown below.

Alternatively, you may specify a public key on file. Select the PEM or Certificate File tabs to load a public key from file. You can use the browse button to examine the file system for the certificate that you wish to use. Public keys typically are stored in .CER, .DER, or .PEM files, but other formats may be used. You can click on the Open button to examine the contents of the certificate. Or, if you have a certificate stored in memory, you can write the contents of the certificate into the text box provided. Note that if you are loading a certificate from memory, the certificate must be Base-64 encoded, or the string representation of the certificate may become corrupted and uninterpretable.

Regardless of how you selected the certificate, once you hit the OK button, the task will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the task was not able to verify the selection, a dialog box will appear instead detailing the verification error.

Note: You may also set SSLAcceptServerCertAcceptAny to True without opening the certificate selection dialog to force the task to unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes.

SSLAcceptServerCertAcceptAny Property (SMIMEEmail Task)

Tells the component to accept any server certificate.

Data Type

Boolean

Default Value

false

Remarks

When set to true, the task will unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes.

SSLCert Property (SMIMEEmail Task)

The certificate to use for client authentication during the SSL handshake.

Data Type

Certificate

Remarks

This property is used to assign a specific certificate for SSL client authentication.

This field is used to set a Private Key Certificate.

Private key certificates may be loaded from the registry, from files in PKCS#12 format, or from a PEM file format. If you click on the ellipses, a certificate selection dialog will open. To select a private key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of certificates which have private keys will be shown below.

To select a private key certificate from a file in PKCS#12 format, select the PFX Store tab. The browse button can be used to examine the file system for PKCS#12 (.pfx or .p12) certificates. If you wish to examine the certificate, provide the password in the field provided and click on the Open button to examine the file store for certificates present. To load a certificate from PEM files, select the PEM tab. Like the PFX file selection, you can specify the password and click the Open button to examine the certificates in the PEM store, or you may paste any PEM data stored in memory.

SSLStartMode Property (SMIMEEmail Task)

Determines how the component starts the SSL negotiation.

Data Type

Enumeration

Possible Values

Automatic (0)
Implicit (1)
Explicit (2)
None (3)

Default Value

Remarks

The SSLStartMode property may have one of the following values:


Automatic	If the remote port is set to the standard plaintext port of the protocol (where applicable), the task will behave the same as if SSLStartMode is set to Explicit. In all other cases, SSL negotiation will be implicit (Implicit).
Implicit	The SSL negotiation will start immediately after the connection is established.
Explicit	The task will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS.
None	No SSL negotiation, no SSL security. All communication will be in plaintext mode.

Subject Property (SMIMEEmail Task)

The subject of the mail message (optional).

Data Type

String

Default Value

Remarks

The string in Subject is sent with a Subject SMTP header to the mail recipient.

This property is not available in the Receiver.

TempPath Property (SMIMEEmail Task)

The path to which temporary files are written at runtime.

Data Type

String

Default Value

Remarks

If you are planning on working with binary files or large files, it is recommended that you set a valid path for this property. When set to a valid path this property tells the task to use temp files when performing operations. If this is not set, all operations are done in memory and require that all input and output is in ASCII.

This property accepts the "%TEMP%" macro, which will be replaced with the default system temporary directory at runtime.

Timeout Property (SMIMEEmail Task)

A timeout for the component.

Data Type

Integer

Default Value

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 task will wait for the operation to complete before returning control.

If Timeout expires, and the operation is not yet complete, the task 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 data is successfully sent or received.

Optionally, the behavior of the task may be changed to absolute timeouts, i.e. the task will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the AbsoluteTimeout configuration setting.

The default value for the Timeout property is 60 (seconds).

UseOAEP Property (SMIMEEmail Task)

Whether to use OAEP when encrypting the MIME data.

Data Type

Boolean

Default Value

false

Remarks

By default, the task will use PKCS1 when encrypting the message. To use Optimal Asymmetric Encryption Padding (OAEP) instead, set this property to true.

This property is not available in the Receiver.

UsePSS Property (SMIMEEmail Task)

Whether to use RSA-PSS when signing.

Data Type

Boolean

Default Value

false

Remarks

To use RSA Probabilistic Signature Scheme (RSA-PSS) when signing, set this property to true. Note that the certificate used to sign does not itself need to be signed with RSA-PSS; any valid RSA certificate may be used with this setting.

This property is not available in the Receiver.

User Property (SMIMEEmail Task)

A user id for login.

Data Type

String

Default Value

Remarks

If the User property is set to a non-empty string, then when connecting to the mail server an AUTH or CRAM-MD5 (depending on the value of AuthMode) command is sent in order to provide authentication information for the user.

NOTE: POP3 and IMAP servers typically require User to be set.

Certificate Type

The digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Store
String

The name of the certificate store for the client certificate.

The StoreType field specifies 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 in order to specify client certificates. If Store has a value, and Subject is set, a search for a certificate is initiated. Please refer to the Subject field for details.

Designations of certificate stores are platform-dependent.

The following are designations of 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.
SPC	Software publisher certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

If the provider is OpenSSL, the certificate store is a file containing a certificate and a private key. This property must be set to the name of the file.

StorePassword
String

If the certificate store is of a type that requires a password, this property is used to specify that password in order to open the certificate store.

StoreType
CertStoreTypes

The type of certificate store for this certificate.

The task supports both public and private keys in a variety of formats. When the cstAuto value is used, the task will automatically determine the type. This field can take one of the following values:


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: This store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.

22 (cstBCFKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: This store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, the necessary data must first be collected using the CERTMGR task. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN. Code Example. SSH Authentication with Security Key: `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Subject
String

The subject of the certificate used for client authentication.

When this property is set, a search is performed in the current certificate store certificate with matching subject.

If an exact match is not found, the store is searched for subjects containing the value of the property.

When setting the property to a partial subject, CN= should be omitted. For example, the following code would find the certificate with subject CN=Test Certificate, OU=People, C=US

Example (Searching with partial subject)

Control.CertSubject = "Test"

If a match is not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

If a matching certificate is found, Subject is set to the full subject of the matching certificate.

Thumbprint
String (read-only)

The thumbprint of the certificate.

This field is used to specify the thumbprint of the certificate. When there are multiple certificates in the store that have the same subject, the thumbprint will be used to distinguish between them.

Firewall Type

The firewall the component will connect through.

Remarks

When connecting through a firewall, this type is used to specify different properties of the firewall such as the firewall Host and the FirewallType.

Fields

AutoDetect

Note that the Port is set automatically when FirewallType is set to a valid value. See the description of the FirewallType field for details.

User
String

A user name if authentication is to be used connecting through a firewall. If the Host is specified, the User and Password fields are used to connect and authenticate to the given Firewall. If the authentication fails, a trappable error is fired.

OAuthAuthorizationParam Type

This type holds details of the OAuth authorization.

Remarks

This type holds details of the OAuth authorization.

Fields

AuthorizationScopes
String

A space separated list of scopes as defined by the authorization server.

AuthorizationString
String

The OAuth Authorization string. This field holds the current OAuth authorization string. This is retrieved during the OAuth authorization process and is used to authenticate the request. This is a string like:

Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ

CacheLocation
String

The location on disk of the OAuth Cache File.

This field specifies the location on disk of the OAuth cache file. This file holds OAuth credentials that may be automatically used during runtime and by other ports using the same provider. The task uses the data within the cache file to automatically refresh expired tokens at runtime. Do not alter the contents of the file directly.

One file for each provider is used by default. For instance for Box the value is: %APPDATA%\nsoftware\CloudStorage BizTalk Adapter\BoxOAuthCache.txt

This value may be specified manually as well.

CallbackURL
String

The Callback URL used during OAuth authorization.

This field specifies the local URL to which the browser is redirected when initially performing authorization. When initially establishing Authorization set this value to the redirect URI that is registered for your application with the service provider. For instance "http://localhost:7777".

The task will parse this URL and start a small embedded web server on the specified port to receive the OAuth response from the provider during OAuth authorization.

This value is required to perform OAuth authorization.

ClientId
String

The id of the client assigned when registering the application.

This field holds the id of the client that was assigned when initially registering the application.

This value is required to perform OAuth authorization.

ClientSecret
String

The secret of the client assigned when registering the application.

This field holds the secret of the client that was assigned when initially registering the application.

This value is required to perform OAuth authorization.

ExpiresIn
Integer

The expiration time of the current OAuth authorization string.

This value is populated after OAuth authorization and holds the expiration time of the OAuth access token as reported by the service provider. This is used at runtime to calculate whether the token should be refreshed before attempting an operation. If the token is expired the task will automatically refresh the token. If the token is not expired the task will use the current token.

This value should not be set manually.

Note: Not all providers provide this value. For instance Dropbox access tokens never expire.

RefreshToken
String

The refresh token received from or sent to the authorization server.

This field holds the refresh token received during the initial OAuth authorization. It is used by the task to automatically request a new AuthorizationString when the current value expires.

ServerAuthURL
String

The URL of the authorization server.

ServerTokenURL
String

The URL of the token server.

ServiceProvider
String

The service provider to authenticate with.

This field defines the service provider. This is used when performing OAuth authorization. OAuth authorization is only applicable to some providers. If the provider does not support OAuth a warning will be displayed. Possible values when using the Cloud Storage task are:

Amazon S3
Azure Blob
Azure File
Backblaze B2
Box.com
Digital Ocean Spaces

TimeStamp
String

The timestamp of the OAuth authorization string.

This field holds the timestamp of when the AuthorizationString was retrieved. This is used in conjunction with ExpiresIn to calculate if refreshing the token is required. For more details see ExpiresIn.

This value should not be set manually.

Config Settings (SMIMEEmail Task)

The task 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 task, access to these internal properties is provided through the Other property.

SMIMEEMail Config Settings

AutoNormalizeLF: Whether to automatically determine how to normalize the MIC when verifying a signature.

If set to False (default), the task will use "\n" as the line ending when normalizing the MIC to verify a signature. When set to true, if verification fails using "\n" the component will automatically try again using "\r\n".

This is only applicable when receiving.

ContinueOnSMIMEError: Specifies whether further emails are processed after encountering an error.

If set, the task will throw a warning and skip any email it cannot process. This is False by default.

SMIMECapabilities: Specifies the algorithms to include in the sMIMECapabilities object in the signature.

If set, the task will include the listed algorithms in the sMIMECapabilities object in the signature. By default this value is empty, and no sMIMECapabilities object will be included. This setting takes a string containing the object Ids of the algorithms to include, separated by a comma. Any parameters should be separated by a dash, like "1.2.840.113549.3.2,1.2.840.113549.3.4-64".

This is only applicable when sending.

Email Config Settings

AddAttachmentsAsMessageParts: Includes attachments as additional parts on the message.

When retrieving messages from a mail server, this setting may be set to True to include incoming attachments as additional message parts. This setting is valid only when receiving messages, and is supported when using both the IMAP and POP protocols. If DuplicateAttachmentAction is set to "overwrite", an error will be thrown if there are duplicate attachments on the same email.

AttachmentEncoding[index]: Content-Transfer-Encoding for attached file (at index).

This configuration setting allows you to set the Content-Transfer-Encoding for each attached file in the Attachments array property. Valid array indices are from 0 to AttachmentCount - 1. When set to one of the below integer values, the attachment will be encoded using the specified encoding. The following encodings are supported:


0	7-bit
1	Quoted-Printable
2	Base64
3	8-bit

AttachmentName[index]: Filename for the attached file (at index).

This configuration setting allows you to set the filename for each attached file when IncludeAttachments is used. Valid array indices are from 0 to AttachmentCount - 1. An index of -1 can be used to set the filename to the same value for all potential attachments. To set the filename for the attachment at index 2, you would set the string "AttachmentName[2]=%SourceFileNameNoExt%.txt".

AttachmentNameSource: Specifies the source location in the MIME entity from which the filename is retrieved.

When set to 0 (default), the task will use the usual header attributes to determine the filename of the attachment that is saved to disk. If these values are not present, the name attribute from the Content-Type header may be used by setting this configuration setting to 1. Note that use of the name attribute for Content-Type is deprecated, but this configuration setting is present to allow for backward compatibility. Possible value are:


0	Auto (default)
1	Auto including legacy attributes

AutoDecodeHeaders: Whether to decode headers.

When retrieving messages from the server, this setting specifies whether headers are automatically decoded by the task. When IncludeHeaders is set to True this setting may also be set to False to ensure that the original header values are included without any processing applied. This is helpful in scenarios when further processing of the message is done outside of the task. The default value is True.

AutoDecodeMessageText: Whether to decode non-MIME message text.

When retrieving non-MIME encoded messages from the server, this setting specifies whether encoded messages (e.g., Base64 encoded message) are automatically decoded by the task. This configuration option is only valid for messages that are not MIME encoded. The default value is False.

DuplicateAttachmentAction: Specifies what action to take when a duplicate filename is encountered.

This setting determines what happens when AttachmentDirectory is set and a duplicate filename is encountered. Possible values are:


0	Overwrite. The file is overwritten in the AttachmentDirectory.
1 (default)	Rename. The file is renamed so both files are kept.

The default value is 1 (Rename). With that setting the filename will include text indicating it is a duplicate. For instance "test.txt" would be renamed to "test-duplicate-1.txt" in the event of a filename conflict. If set to 0 (Overwrite) the previous file will be overwritten.

FoldHeaders: Whether incoming message headers should be folded.

By default, when IncludeHeaders is true, the task will unfold headers so that each header is on a single line. To instruct the task to fold the headers, set this configuration setting to True. Folding the headers may resolve line-length issues if the header value is long.

This is only applicable when receiving. The default value is False.

Logoff: Whether or not to logoff from the server after execution.

This configuration is only used when PersistentConnection has been set to true. Set this to true to tell the task to logoff from the persisted connection once execution completes.

The default for this configuration setting is false.

MaskSensitive: Whether sensitive properties should be masked when logging.

By default, Verbose logging will include the raw commands sent to the mail server in plain text. To mask sensitive values such as passwords and prevent them from appearing in the log, set this option to True. The default value is true.

MaxParts: The maximum number of parts to be parsed from a mime message.

This config should be set to limit the amount of parts that will be parsed from an email. By default, this value is 100. Therefore up to 100 parts (the body and 99 attachments) will be parsed from an email by default.

MessageHTMLFile: Specifies a file that will be included as the email's HTML content.

This configuration setting can be used to specify a file that will be included in the HTML content of the email. If the MessageHTML property is also specified, the contents of the file will be included after the value in the MessageHTML property.

MoveTo: Specifies the IMAP folder on the server to which messages will be moved.

If set, the task will move the downloaded messages to the folder specified. This is only applicable when ServerType is set to IMAP. Only successfully downloaded messages will be moved.

This is only applicable when receiving.

ReturnOnlyPlainTextPart: Specifies if the task should return the first plain text part or the entire message.

If set to true the task will return only the first plain text part of a message. This is false by default. This is only applicable when receiving messages.

ReturnPath: Sets the Return-Path to be used for sending email.

Setting this property sets the Return-Path to be used for sending email. If this is not set, the value in From is used.

This is only applicable when sending emails.

UIDMode: If True, permanent message identifiers will be used instead of temporary identifiers.

When False, the IMAP server uses temporary message identifiers that are valid only during the current session. If this configuration setting is True (default), permanent message identifiers will be used instead.

The IMAP protocol operations where UID mode is used are the following: COPY, FETCH, STORE, SEARCH.

Note: This configuration setting only applies when ServerType is set to IMAP;

SSL Config Settings

ReuseSSLSession: Determines if the SSL session is reused.

If set to true, the task 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 task is the same.

SSLCipherStrength: The minimum cipher strength used for bulk encryption.

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.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

SSLEnabledCipherSuites: The cipher suite to be used in an SSL negotiation.

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 task 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 UseInternalSecurityAPI is False (default): // The "Other" property could contain ONE of the following lines: SSLEnabledCipherSuites=* SSLEnabledCipherSuites=CALG_AES_256 SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES Possible values when UseInternalSecurityAPI is False (default) include:

If SSLEnabledProtocols is configured to use TLS 1.3 the following values are supported:

TLS_AES_128_GCM_SHA256
TLS_AES_256_GCM_SHA384

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols: Used to enable/disable the supported security protocols.

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) (Experimental)
TLS1.2	3072 (Hex C00) (Default)
TLS1.1	768 (Hex 300) (Default)
TLS1	192 (Hex C0) (Default)
SSL3	48 (Hex 30)
SSL2	12 (Hex 0C)

Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.

Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.

SSLIncludeCertChain: Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the transport log contains the full certificate chain. By default this value is False and only the leaf certificate will be present.

If set to True all certificates returned by the server will be present in the transport log. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.

SSLSecurityFlags: Flags that control certificate verification.

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).

TLS12SignatureAlgorithms: Defines the allowed TLS 1.2 signature algorithms when UseInternalSecurityAPI is True.

This setting specifies the allowed server certificate signature algorithms when UseInternalSecurityAPI is True and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the task 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 task will fail with an error.

The format of this value is a comma separated list of hash-signature combinations. For instance: // The "Other" could contain ALL of these lines: UseInternalSecurityAPI=true SSLEnabledProtocols=3072 TLS12SignatureAlgorithms=sha1-rsa,sha1-dsa,sha256-rsa,sha256-dsa The default value for this setting is "sha1-rsa,sha1-dsa,sha224-rsa,sha224-dsa,sha256-rsa,sha256-dsa,sha384-rsa,sha384-dsa,sha512-rsa,sha512-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.

TLS12SupportedGroups: The supported groups for ECC.

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 UseInternalSecurityAPI is set to True, the values refer to the supported groups for ECC. The following values are supported:

"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

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_x25519" (default)
"ecdhe_x448"
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1"
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096"
"ffdhe_6144"
"ffdhe_8192"

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

"rsa_pkcs1_sha256" (default)
"rsa_pkcs1_sha384" (default)
"rsa_pkcs1_sha512" (default)

The default value is rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.

TLS13SupportedGroups: The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

"ecdhe_x25519" (default)
"ecdhe_x448" (default)
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096" (default)
"ffdhe_6144" (default)
"ffdhe_8192" (default)

General Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

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.

LocalHost: The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

The LocalHost configuration contains the name of the local host as obtained by the Gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the task initiate connections (or accept in the case of server tasks) only through that interface.

If the task is connected, the LocalHost configuration 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).

TcpNoDelay: Whether or not to delay when sending packets.

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.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to False, the task will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to True.

Setting this configuration setting to True tells the task 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.

If using the .NET Standard Library, this setting will be True on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all tasks used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
