The XMLEncrypt class is used to encrypt and decrypt XML.

Syntax

ipworksencrypt.XMLEncrypt

Remarks

The XMLEncrypt class provides a simple API for encrypting and decrypting XML. The Encrypt method will encrypt the XML document, or a specific element. Multiple elements may be encrypted at one time by setting EncryptedDataDetails. The Decrypt method will decrypt the XML document.

The class supports encrypting and decrypting with a shared SymmetricKey, and also using asymmetric encryption to encrypt the SymmetricKey (session key) via the RecipientCert and Certificate properties.

Encrypt

To begin first specify a XML document by calling SetInputStream or setting InputFile, or InputXML.

The EncryptedDataDetails property specify the XML element to encrypt. By default the entire XML document is encrypted.

The SymmetricKey property specifies the key which will be used to encrypt the data.

If the RecipientCert property is set, then the SymmetricKey will be encrypted and included in the encrypted data. This allows for the recipient to decrypt the key, with their certificate. Encrypting the symmetric key is also referred to as using a session key. The benefit of using certificate to encrypt and decrypt a session key (SymmetricKey) is that knowledge of the key value is not needed ahead of time to process the encrypted data. Note that if specified, RecipientCert MUST have a RSA key, not a DSA key.

If the RecipientCert property is not set, then the recipient must know the value of SymmetricKey before decrypting the XML. The KeyName setting may be set to provide a key identifier to the recipient.

Optionally set EncryptingAlgorithm, and then call Encrypt to encrypt the XML.

The following properties are applicable when calling this method:

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

Decrypt

To begin first specify a XML document by calling SetInputStream or setting InputFile, or InputXML.

The SymmetricKey property specifies the key used to decrypt the data. This may be set before calling Decrypt or inside the EncryptedDataInfo event. The EncryptedDataInfo event fires once for each encrypted element when Decrypt is called.

If the data was encrypted using an session key, set the Certificate property to the certificate with private key before calling Decrypt. The certificate will be used to decrypt the encrypted session key. In this case the SymmetricKey property is ignored.

By default this value is False and the class will use PKCS1.

Config Method (XMLEncrypt 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.

Decrypt Method (XMLEncrypt Class)

Decrypts the XML.

Syntax

public void decrypt();

Remarks

This method decrypts the specified XML.

To begin first specify a XML document by calling SetInputStream or setting InputFile, or InputXML.

The SymmetricKey property specifies the key used to decrypt the data. This may be set before calling Decrypt or inside the EncryptedDataInfo event. The EncryptedDataInfo event fires once for each encrypted element when Decrypt is called.

If the data was encrypted using an session key, set the Certificate property to the certificate with private key before calling Decrypt. The certificate will be used to decrypt the encrypted session key. In this case the SymmetricKey property is ignored.

The following properties are applicable when calling this method:

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

DoEvents Method (XMLEncrypt Class)

This method processes events from the internal message queue.

Syntax

public void doEvents();

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Encrypt Method (XMLEncrypt Class)

Encrypts the XML.

Syntax

public void encrypt();

Remarks

This method encrypts the specified XML.

To begin first specify a XML document by calling SetInputStream or setting InputFile, or InputXML.

The EncryptedDataDetails property specify the XML element to encrypt. By default the entire XML document is encrypted.

The SymmetricKey property specifies the key which will be used to encrypt the data.

If the RecipientCert property is set, then the SymmetricKey will be encrypted and included in the encrypted data. This allows for the recipient to decrypt the key, with their certificate. Encrypting the symmetric key is also referred to as using a session key. The benefit of using certificate to encrypt and decrypt a session key (SymmetricKey) is that knowledge of the key value is not needed ahead of time to process the encrypted data. Note that if specified, RecipientCert MUST have a RSA key, not a DSA key.

If the RecipientCert property is not set, then the recipient must know the value of SymmetricKey before decrypting the XML. The KeyName setting may be set to provide a key identifier to the recipient.

Optionally set EncryptingAlgorithm, and then call Encrypt to encrypt the XML.

The following properties are applicable when calling this method:

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

SetInputStream Method (XMLEncrypt Class)

Sets the stream from which the class will read data to encrypt or decrypt.

Syntax

public void setInputStream(java.io.InputStream inputStream);

Remarks

This method sets the stream from which the class will read data to encrypt or decrypt. If an input stream is set before calling Encrypt or Decrypt, the data is read from the input stream instead of from the InputFile or InputXML properties.

The content of the stream will be read from the current position all the way to the end and no bytes will be skipped.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

SetOutputStream Method (XMLEncrypt Class)

The stream to which the class will write the encrypted or decrypted XML.

Syntax

public void setOutputStream(java.io.OutputStream outputStream);

Remarks

This method sets the stream to which the class will write the encrypted or decrypted XML. If an output stream is set before calling Encrypt or Decrypt, the class will write the data to the output stream instead of populating OutputXML or writing to OutputFile.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:
  • SetOutputStream
  • OutputFile
  • OutputXML: The output data is written to this property if no other destination is specified.

EncryptedDataInfo Event (XMLEncrypt Class)

Fired once for each encrypted element when Decrypt is called.

Syntax

public class DefaultXMLEncryptEventListener implements XMLEncryptEventListener {
  ...
  public void encryptedDataInfo(XMLEncryptEncryptedDataInfoEvent e) {}
  ...
}

public class XMLEncryptEncryptedDataInfoEvent {
  public String encryptedDataId;
  public int scope;
  public String MIMEType;
}

Remarks

This event fires once for each encrypted element in the XML document when Decrypt is called. The parameters of this event provide information about the encrypted data. Additionally, the KeyName setting may be queried to identify the encryption key. SymmetricKey may be set from within this event.

EncryptedDataId is the Id of the encrypted data (if any).

Scope indicates the scope of the encrypted data. This defines whether the entire XML element was encrypted, or only the content. Possible values are:

0Element
1Content

MIMEType holds the MIME type of the encrypted data (if any). For example: "image/png".

Error Event (XMLEncrypt Class)

Fired when information is available about errors during data delivery.

Syntax

public class DefaultXMLEncryptEventListener implements XMLEncryptEventListener {
  ...
  public void error(XMLEncryptErrorEvent e) {}
  ...
}

public class XMLEncryptErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

  ...
}

public class XMLEncryptProgressEvent {
  public long bytesProcessed;
  public int percentProcessed;
  public int operation;
  public boolean isEOF; //read-write
}

Remarks

This event is fired automatically as data is processed by the class.

The PercentProcessed parameter indicates the current status of the operation.

The BytesProcessed parameter holds the total number of bytes processed so far.

The Operation parameter is only applicable when either ReadFromProgressEvent or WriteToProgressEvent is set to True. This parameter defines whether a Read or Write operation is required. If the configuration settings are not set this parameter will always return 0. Possible values are:

0None
1Read
2Write

The IsEOF parameter is only applicable when either ReadFromProgressEvent or WriteToProgressEvent is set to True. This parameter defines whether the Read or Write operation is complete. When the Operation is Read (1) this parameter must be set to indicate that all data has been supplied to the class. When the Operation is Write (2) this value may be queried to determine when all data has been processed.

Status Event (XMLEncrypt Class)

Provides information about the current operation.

Syntax

public class DefaultXMLEncryptEventListener implements XMLEncryptEventListener {
  ...
  public void status(XMLEncryptStatusEvent e) {}
  ...
}

public class XMLEncryptStatusEvent {
  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.

    14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
    15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
    16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
    17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
    18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
    19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
    21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store).

    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 class. 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.

    Version
    String (read-only)
    Default Value: ""

    The certificate's version number. The possible values are the strings "V1", "V2", and "V3".

    Subject
    String
    Default Value: ""

    The subject of the certificate used for client authentication.

    This field will be populated with the full subject of the loaded certificate. When loading a certificate, the subject is used to locate the certificate in the store.

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

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

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

    The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

    FieldMeaning
    CNCommon Name. This is commonly a hostname like www.server.com.
    OOrganization
    OUOrganizational Unit
    LLocality
    SState
    CCountry
    EEmail Address

    If a field value contains a comma, it must be quoted.

    Encoded
    String
    Default Value: ""

    The certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

    When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

    EncodedB
    byte[]
    Default Value: ""

    The certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

    When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

    Constructors

    public Certificate();

    Creates a instance whose properties can be set. This is useful for use with when generating new certificates. 

    public Certificate( certificateFile);

    Opens CertificateFile and reads out the contents as an X.509 public key. 

    public Certificate( encoded);

    Parses Encoded as an X.509 public key. 

    public Certificate( storeType,  store,  storePassword,  subject);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format. 

    public Certificate( storeType,  store,  storePassword,  subject,  configurationString);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

    ConfigurationString is a newline-separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CryptoAPI option. The default value is True (the key is persisted). "Thumbprint" - an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to the cstUser , cstMachine , cstPublicKeyFile , and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations.

    After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format. 

    public Certificate( storeType,  store,  storePassword,  encoded);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the class will load Encoded as an X.509 certificate and search the opened store for a corresponding private key. 

    public Certificate( storeType,  store,  storePassword,  subject);

    StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array containing the certificate data. StorePassword is the password used to protect the store.

    After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

    Config Settings (XMLEncrypt 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.

    XMLEnc Config Settings

    EncryptedKeyXPath:   The XPath of the EncryptedKey element.

    This setting specifies the XPath where the EncryptedKey element will be written. In most cases this does not need to be changed. By default it is included in the EncryptedData element.

    KeyName:   The name of the key used to encrypt the XML.

    This setting optionally holds the key name which may be useful to the recipient to help identify the key used to encrypt the data. This may be set before calling Encrypt. When calling Decrypt this may be queried inside the EncryptedDataInfo event.

    Note that this value is only informative, it does not affect processing.

    LogLevel:   Specifies the level of detail that is logged.

    This setting controls the level of detail that is logged through the Status event. Possible values are:

    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.
    OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used with OAEP.

    This configuration setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"

    OAEPParams:   The hex encoded OAEP parameters.

    This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when UseOAEP is set to True. The specified value should be hex encoded.

    OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

    This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"
    The RSA hash algorithm used when encrypting a key.

    When encryption is enabled, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the message content. Possible values are:

    • "SHA1" (default)
    • "SHA224"
    • "SHA256"
    • "SHA384"
    • "SHA512"
    OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

    This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

    • "SHA1"
    • "SHA224"
    • "SHA256" (default)
    • "SHA384"
    • "SHA512"
    • "RIPEMD160"
    • "MD2"
    • "MD5"
    • "MD5SHA1"
    The RSA hash algorithm used when encrypting a key.

    When encryption is enabled, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the message content. Possible values are:

    • "SHA1" (default)
    • "SHA224"
    • "SHA256"
    • "SHA384"
    • "SHA512"
    ReadFromProgressEvent:   Whether to read input data from inside the progress event.

    When set to True this setting allows input data to be specified from within the Progress event. The class will repeatedly fire the Progress event to ask for data. Inside the event set InputXML when the Operation parameter of the event is 1 (Read). When all data has been provided set the IsEOF parameter of the event to True. This allows input data to be chunked and provided piece by piece. The default value is False.

    WriteToProgressEvent:   Whether to write output data so it is accessible from inside the progress event.

    When set to True this setting allows output data to be obtained from within the Progress event. The class will repeatedly fire the Progress event to provide output data. Inside the event check OutputXML when the Operation parameter of the event is 2 (Write). The IsEOF parameter should be checked inside the event to determine when all output data has been provided. This allows output data to be chunked and obtained piece by piece. The default value is False.

    Base Config Settings

    BuildInfo:   Information about the product's build.

    When queried, this setting will return a string containing information about the product's build.

    GUIAvailable:   Whether or not a message loop is available for processing events.

    In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

    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.

    LicenseInfo:   Information about the current license.

    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.
    MaskSensitiveData:   Whether sensitive data is masked in log messages.

    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.

    UseDaemonThreads:   Whether threads created by the class are daemon threads.

    If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

    UseFIPSCompliantAPI:   Tells the class whether or not to use FIPS certified APIs.

    When set to true, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

    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.

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

    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.

    This setting is set to false by default on all platforms.
