# XMLEncrypt Component

The XMLEncrypt component is used to encrypt and decrypt XML.

## Syntax

```text
nsoftware.IPWorksEncrypt.XMLEncrypt
```

## Remarks

The XMLEncrypt component provides a simple API for encrypting and decrypting XML. The [Encrypt](#encrypt-method-xmlencrypt-component) method will encrypt the XML document, or a specific element. Multiple elements may be encrypted at one time by setting [EncryptedDataDetails](#encrypteddatadetails-property-xmlencrypt-component). The [Decrypt](#decrypt-method-xmlencrypt-component) method will decrypt the XML document.

The component supports encrypting and decrypting with a shared [SymmetricKey](#symmetrickey-property-xmlencrypt-component), and also using asymmetric encryption to encrypt the [SymmetricKey](#symmetrickey-property-xmlencrypt-component) (session key) via the [RecipientCert](#recipientcert-property-xmlencrypt-component) and [Certificate](#certificate-property-xmlencrypt-component) properties.

**Encrypt**

To begin first specify a XML document by calling [SetInputStream](#setinputstream-method-xmlencrypt-component) or setting [InputFile](#inputfile-property-xmlencrypt-component), or [InputXML](#inputxml-property-xmlencrypt-component).

The [EncryptedDataDetails](#encrypteddatadetails-property-xmlencrypt-component) property specify the XML element to encrypt. By default the entire XML document is encrypted.

The [SymmetricKey](#symmetrickey-property-xmlencrypt-component) property specifies the key which will be used to encrypt the data.

If the [RecipientCert](#recipientcert-property-xmlencrypt-component) property is set, then the [SymmetricKey](#symmetrickey-property-xmlencrypt-component) 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](#symmetrickey-property-xmlencrypt-component)) is that knowledge of the key value is not needed ahead of time to process the encrypted data. Note that if specified, [RecipientCert](#recipientcert-property-xmlencrypt-component) MUST have a RSA key, not a DSA key.

If the [RecipientCert](#recipientcert-property-xmlencrypt-component) property is not set, then the recipient must know the value of [SymmetricKey](#symmetrickey-property-xmlencrypt-component) before decrypting the XML. The [KeyName](#KeyName) setting may be set to provide a key identifier to the recipient.

Optionally set [EncryptingAlgorithm](#encryptingalgorithm-property-xmlencrypt-component), and then call [Encrypt](#encrypt-method-xmlencrypt-component) to encrypt the XML.

The following properties are applicable when calling this method:

- [SymmetricKey](#symmetrickey-property-xmlencrypt-component) (required)
- [EncryptingAlgorithm](#encryptingalgorithm-property-xmlencrypt-component)
- [EncryptedDataDetails](#encrypteddatadetails-property-xmlencrypt-component)
- [RecipientCert](#recipientcert-property-xmlencrypt-component)
- [KeyName](#KeyName)

**Input and Output Properties**

The component 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](#setinputstream-method-xmlencrypt-component)
- [InputFile](#inputfile-property-xmlencrypt-component)
- [InputXML](#inputxml-property-xmlencrypt-component)

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

- [SetOutputStream](#setoutputstream-method-xmlencrypt-component)
- [OutputFile](#outputfile-property-xmlencrypt-component)
- [OutputXML](#outputxml-property-xmlencrypt-component): The output data is written to this property if no other destination is specified.

**Decrypt**

To begin first specify a XML document by calling [SetInputStream](#setinputstream-method-xmlencrypt-component) or setting [InputFile](#inputfile-property-xmlencrypt-component), or [InputXML](#inputxml-property-xmlencrypt-component).

The [SymmetricKey](#symmetrickey-property-xmlencrypt-component) property specifies the key used to decrypt the data. This may be set before calling [Decrypt](#decrypt-method-xmlencrypt-component) or inside the [EncryptedDataInfo](#encrypteddatainfo-event-xmlencrypt-component) event. The [EncryptedDataInfo](#encrypteddatainfo-event-xmlencrypt-component) event fires once for each encrypted element when [Decrypt](#decrypt-method-xmlencrypt-component) is called.

If the data was encrypted using an session key, set the [Certificate](#certificate-property-xmlencrypt-component) property to the certificate with private key before calling [Decrypt](#decrypt-method-xmlencrypt-component). The certificate will be used to decrypt the encrypted session key. In this case the [SymmetricKey](#symmetrickey-property-xmlencrypt-component) property is ignored.

The following properties are applicable when calling this method:

- [SymmetricKey](#symmetrickey-property-xmlencrypt-component)
- [Certificate](#certificate-property-xmlencrypt-component)

**Input and Output Properties**

The component 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](#setinputstream-method-xmlencrypt-component)
- [InputFile](#inputfile-property-xmlencrypt-component)
- [InputXML](#inputxml-property-xmlencrypt-component)

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

- [SetOutputStream](#setoutputstream-method-xmlencrypt-component)
- [OutputFile](#outputfile-property-xmlencrypt-component)
- [OutputXML](#outputxml-property-xmlencrypt-component): The output data is written to this property if no other destination is specified.

**Encrypt Notes**

When calling [Encrypt](#encrypt-method-xmlencrypt-component) if the [RecipientCert](#recipientcert-property-xmlencrypt-component) property is set, then the SymmetricKey will be encrypted and included in the XML as an encrypted key. Using asymmetric encryption to encrypt the SymmetricKey allows for secure transmission of the key. This is also referred to as using a session key, as no prior knowledge of the SymmetricKey is required by the recipient.

If the [RecipientCert](#recipientcert-property-xmlencrypt-component) property is set and SymmetricKey is left empty, then a SymmetricKey value will automatically be generated by the component when [Encrypt](#encrypt-method-xmlencrypt-component) is called.

When calling [Encrypt](#encrypt-method-xmlencrypt-component) if the [RecipientCert](#recipientcert-property-xmlencrypt-component) property is are not set, then the SymmetricKey value must be known by the recipient before the message can be decrypted.

Whether to use Optimal Asymmetric Encryption Padding (OAEP).

## Syntax

```text
public bool UseOAEP { get; set; }
```

## Default Value

False

## Remarks

This setting specifies whether to use Optimal Asymmetric Encryption Padding (OAEP) when encrypting the [SymmetricKey](#symmetrickey-property-xmlencrypt-component) with the certificate specified by [RecipientCert](#recipientcert-property-xmlencrypt-component). It is only applicable when calling [Encrypt](#encrypt-method-xmlencrypt-component) and [RecipientCert](#recipientcert-property-xmlencrypt-component) is specified.

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

# Config Method ([XMLEncrypt](#xmlencrypt-component) Component)

Sets or retrieves a configuration setting.

## Syntax

```text
public string Config(string configurationString);

Async Version
public async Task<string> Config(string configurationString);
public async Task<string> Config(string configurationString, CancellationToken cancellationToken);
```

## Remarks

Config is a generic method available in every component. It is used to set and retrieve [configuration settings](#config-settings-xmlencrypt-component) for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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](#config-settings-xmlencrypt-component), you must call *Config("PROPERTY")*. The value will be returned as a string.

# Decrypt Method ([XMLEncrypt](#xmlencrypt-component) Component)

Decrypts the XML.

## Syntax

```text
public void Decrypt();

Async Version
public async Task Decrypt();
public async Task Decrypt(CancellationToken cancellationToken);
```

## Remarks

This method decrypts the specified XML.

To begin first specify a XML document by calling [SetInputStream](#setinputstream-method-xmlencrypt-component) or setting [InputFile](#inputfile-property-xmlencrypt-component), or [InputXML](#inputxml-property-xmlencrypt-component).

The [SymmetricKey](#symmetrickey-property-xmlencrypt-component) property specifies the key used to decrypt the data. This may be set before calling Decrypt or inside the [EncryptedDataInfo](#encrypteddatainfo-event-xmlencrypt-component) event. The [EncryptedDataInfo](#encrypteddatainfo-event-xmlencrypt-component) event fires once for each encrypted element when Decrypt is called.

If the data was encrypted using an session key, set the [Certificate](#certificate-property-xmlencrypt-component) 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](#symmetrickey-property-xmlencrypt-component) property is ignored.

The following properties are applicable when calling this method:

- [SymmetricKey](#symmetrickey-property-xmlencrypt-component)
- [Certificate](#certificate-property-xmlencrypt-component)

**Input and Output Properties**

The component 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](#setinputstream-method-xmlencrypt-component)
- [InputFile](#inputfile-property-xmlencrypt-component)
- [InputXML](#inputxml-property-xmlencrypt-component)

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

- [SetOutputStream](#setoutputstream-method-xmlencrypt-component)
- [OutputFile](#outputfile-property-xmlencrypt-component)
- [OutputXML](#outputxml-property-xmlencrypt-component): The output data is written to this property if no other destination is specified.

# DoEvents Method ([XMLEncrypt](#xmlencrypt-component) Component)

This method processes events from the internal message queue.

## Syntax

```text
public void DoEvents();

Async Version
public async Task DoEvents();
public async Task DoEvents(CancellationToken cancellationToken);
```

## Remarks

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

# Encrypt Method ([XMLEncrypt](#xmlencrypt-component) Component)

Encrypts the XML.

## Syntax

```text
public void Encrypt();

Async Version
public async Task Encrypt();
public async Task Encrypt(CancellationToken cancellationToken);
```

## Remarks

This method encrypts the specified XML.

To begin first specify a XML document by calling [SetInputStream](#setinputstream-method-xmlencrypt-component) or setting [InputFile](#inputfile-property-xmlencrypt-component), or [InputXML](#inputxml-property-xmlencrypt-component).

The [EncryptedDataDetails](#encrypteddatadetails-property-xmlencrypt-component) property specify the XML element to encrypt. By default the entire XML document is encrypted.

The [SymmetricKey](#symmetrickey-property-xmlencrypt-component) property specifies the key which will be used to encrypt the data.

If the [RecipientCert](#recipientcert-property-xmlencrypt-component) property is set, then the [SymmetricKey](#symmetrickey-property-xmlencrypt-component) 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](#symmetrickey-property-xmlencrypt-component)) is that knowledge of the key value is not needed ahead of time to process the encrypted data. Note that if specified, [RecipientCert](#recipientcert-property-xmlencrypt-component) MUST have a RSA key, not a DSA key.

If the [RecipientCert](#recipientcert-property-xmlencrypt-component) property is not set, then the recipient must know the value of [SymmetricKey](#symmetrickey-property-xmlencrypt-component) before decrypting the XML. The [KeyName](#KeyName) setting may be set to provide a key identifier to the recipient.

Optionally set [EncryptingAlgorithm](#encryptingalgorithm-property-xmlencrypt-component), and then call Encrypt to encrypt the XML.

The following properties are applicable when calling this method:

- [SymmetricKey](#symmetrickey-property-xmlencrypt-component) (required)
- [EncryptingAlgorithm](#encryptingalgorithm-property-xmlencrypt-component)
- [EncryptedDataDetails](#encrypteddatadetails-property-xmlencrypt-component)

## Syntax

```text
public void SetInputStream(System.IO.Stream inputStream);

Async Version
public async Task SetInputStream(System.IO.Stream inputStream);
public async Task SetInputStream(System.IO.Stream inputStream, CancellationToken cancellationToken);
```

## Remarks

This method sets the stream from which the component will read data to encrypt or decrypt. If an input stream is set before calling [Encrypt](#encrypt-method-xmlencrypt-component) or [Decrypt](#decrypt-method-xmlencrypt-component), the data is read from the input stream instead of from the [InputFile](#inputfile-property-xmlencrypt-component) or [InputXML](#inputxml-property-xmlencrypt-component) 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**

# EncryptedDataInfo Event ([XMLEncrypt](#xmlencrypt-component) Component)

Fired once for each encrypted element when Decrypt is called.

## Syntax

```text
public event OnEncryptedDataInfoHandler OnEncryptedDataInfo;

public delegate void OnEncryptedDataInfoHandler(object sender, XMLEncryptEncryptedDataInfoEventArgs e);

public class XMLEncryptEncryptedDataInfoEventArgs : EventArgs {
  public string EncryptedDataId { get; }
  public int Scope { get; }
  public string MIMEType { get; }
}
```

## Remarks

This event fires once for each encrypted element in the XML document when [Decrypt](#decrypt-method-xmlencrypt-component) is called. The parameters of this event provide information about the encrypted data. Additionally, the [KeyName](#KeyName) setting may be queried to identify the encryption key. [SymmetricKey](#symmetrickey-property-xmlencrypt-component) 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:

|  |  |
| --- | --- |
| 0 | Element |
| 1 | Content |

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

# Error Event ([XMLEncrypt](#xmlencrypt-component) Component)

Fired when information is available about errors during data delivery.

## Syntax

```text
public event OnErrorHandler OnError;

public delegate void OnErrorHandler(object sender, XMLEncryptErrorEventArgs e);

public class XMLEncryptErrorEventArgs : EventArgs {
  public int ErrorCode { get; }
  public string Description { get; }
}
```

## Remarks

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

The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-xmlencrypt-component) section.

# Progress Event ([XMLEncrypt](#xmlencrypt-component) Component)

Fired as progress is made.

## Syntax

```text
public event OnProgressHandler OnProgress;

public delegate void OnProgressHandler(object sender, XMLEncryptProgressEventArgs e);

public class XMLEncryptProgressEventArgs : EventArgs {
  public long BytesProcessed { get; }
  public int PercentProcessed { get; }
  public int Operation { get; }
  public bool IsEOF { get; set; }
}
```

## Remarks

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

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](#ReadFromProgressEvent) or [WriteToProgressEvent](#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:

|  |  |
| --- | --- |
| 0 | None |
| 1 | Read |
| 2 | Write |

The *IsEOF* parameter is only applicable when either [ReadFromProgressEvent](#ReadFromProgressEvent) or [WriteToProgressEvent](#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 component. When the *Operation* is Write (2) this value may be queried to determine when all data has been processed.

# Status Event ([XMLEncrypt](#xmlencrypt-component) Component)

Provides information about the current operation.

## Syntax

```text
public event OnStatusHandler OnStatus;

public delegate void OnStatusHandler(object sender, XMLEncryptStatusEventArgs e);

public class XMLEncryptStatusEventArgs : EventArgs {
  public string Message { get; }
}
```

## 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](#LogLevel) setting.

                               "CN=cert_subject");
sftp.SSHUser = "test";
sftp.SSHLogon("myhost", 22);
```

```csharp
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);
```

# Config Settings ([XMLEncrypt](#xmlencrypt-component) Component)

 The component 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 component, access to these *internal properties* is provided through the [Config](#config-method-xmlencrypt-component) 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](#encrypt-method-xmlencrypt-component). When calling [Decrypt](#decrypt-method-xmlencrypt-component) this may be queried inside the [EncryptedDataInfo](#encrypteddatainfo-event-xmlencrypt-component) 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](#status-event-xmlencrypt-component) 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](#useoaep-property-xmlencrypt-component) is set to True. The default value is *SHA256*. Possible values are as follows:

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

Note: This setting is not applicable when [UseFIPSCompliantAPI](#UseFIPSCompliantAPI) is set to *true* or when the private key of the signing certificate is not exportable since the underlying system implementation does not support separate [OAEPRSAHashAlgorithm](#OAEPRSAHashAlgorithm) and [OAEPMGF1HashAlgorithm](#OAEPMGF1HashAlgorithm) values. In this case the [OAEPRSAHashAlgorithm](#OAEPRSAHashAlgorithm) is also used for MGF1.

**OAEPParams**: The hex encoded OAEP parameters.This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when [UseOAEP](#useoaep-property-xmlencrypt-component) 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](#useoaep-property-xmlencrypt-component) 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](#useoaep-property-xmlencrypt-component) 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](#progress-event-xmlencrypt-component) event. The component will repeatedly fire the [Progress](#progress-event-xmlencrypt-component) event to ask for data. Inside the event set [InputXML](#inputxml-property-xmlencrypt-component) 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](#progress-event-xmlencrypt-component) event. The component will repeatedly fire the [Progress](#progress-event-xmlencrypt-component) event to provide output data. Inside the event check [OutputXML](#outputxml-property-xmlencrypt-component) 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 component 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](#GUIAvailable) to *false* will ensure that the component 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 component 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*.

**UseFIPSCompliantAPI**: Tells the component whether or not to use FIPS certified APIs.When set to *true*, the component 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.

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 components 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](https://www.nsoftware.com/kb/articles/fips.rst) article.

NOTE: This setting is applicable only on Windows.

NOTE: Enabling FIPS compliance requires a special license; please contact [sales@nsoftware.com](mailto:sales@nsoftware.com) for details.

**UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the component 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 component 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.

NOTE: This setting is static. The value set is applicable to all components 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.
