The XMLEncrypt component is used to encrypt and decrypt XML.

Syntax

TipcXMLEncrypt

Remarks

The XMLEncrypt component 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 the EncryptedDataDetail* properties. The Decrypt method will decrypt the XML document.

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

Encrypt

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

The EncryptedDataDetail* properties 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* properties are 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* properties are 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 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:

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

Decrypt

To begin first specify a XML document by 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 Cert* properties 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:

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:

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

property SymmetricKeyB: TBytes read get_SymmetricKeyB write set_SymmetricKeyB;

Default Value

''

Remarks

This property specifies the symmetric key used to encrypt and decrypt the XML.

Encrypt Notes

When calling Encrypt if the RecipientCert* properties are 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* properties are set and SymmetricKey is left empty, then a SymmetricKey value will automatically be generated by the component when Encrypt is called.

When calling Encrypt if the RecipientCert* properties are are not set, then the SymmetricKey value must be known by the recipient before the message can be decrypted.

Decrypt Notes

When calling Decrypt if the data contains an encrypted key the component will attempt to use the certificate specified by the Cert* properties to decrypt the encrypted key and this property is ignored.

When calling Decrypt if the data does not contain an encrypted key then SymmetricKey must be set either before calling Decrypt, or within the EncryptedDataInfo event.

Legal Key and Block Sizes (in bits)

AES DES 3DES
Minimum Key Size 128 64 128
Maximum Key Size 256 64 192
Key Size Step 64 0 64
Block Size 128 64 64

This property is not available at design time.

UseOAEP Property (XMLEncrypt Component)

Whether to use Optimal Asymmetric Encryption Padding (OAEP).

Syntax

property UseOAEP: Boolean read get_UseOAEP write set_UseOAEP;

Default Value

false

Remarks

This setting specifies whether to use Optimal Asymmetric Encryption Padding (OAEP) when encrypting the SymmetricKey with the certificate specified by RecipientCert. It is only applicable when calling Encrypt and RecipientCert is specified.

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

Config Method (XMLEncrypt Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings 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, you must call Config("PROPERTY"). The value will be returned as a string.

Decrypt Method (XMLEncrypt Component)

Decrypts the XML.

Syntax

procedure Decrypt();

Remarks

This method decrypts the specified XML.

To begin first specify a XML document by 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 Cert* properties 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:

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:

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

DoEvents Method (XMLEncrypt Component)

Processes events from the internal message queue.

Syntax

procedure DoEvents();

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 Component)

Encrypts the XML.

Syntax

procedure Encrypt();

Remarks

This method encrypts the specified XML.

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

The EncryptedDataDetail* properties 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* properties are 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* properties are 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 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:

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

Reset Method (XMLEncrypt Component)

Resets the component.

Syntax

procedure Reset();

Remarks

When called, the component will reset all of its properties to their default values.

SetInputStream Method (XMLEncrypt Component)

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

Syntax

procedure SetInputStream(InputStream: TStream);

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 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 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:

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

SetOutputStream Method (XMLEncrypt Component)

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

Syntax

procedure SetOutputStream(OutputStream: TStream);

Remarks

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

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:

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

EncryptedDataInfo Event (XMLEncrypt Component)

Fired once for each encrypted element when Decrypt is called.

Syntax

type TEncryptedDataInfoEvent = procedure (
  Sender: TObject;
  const EncryptedDataId: String;
  Scope: Integer;
  const MIMEType: String
) of Object;

property OnEncryptedDataInfo: TEncryptedDataInfoEvent read FOnEncryptedDataInfo write FOnEncryptedDataInfo;

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 Component)

Information about errors during data delivery.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent read FOnError write FOnError;

Remarks

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

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Progress Event (XMLEncrypt Component)

Fired as progress is made.

Syntax

type TProgressEvent = procedure (
  Sender: TObject;
  BytesProcessed: Int64;
  PercentProcessed: Integer;
  Operation: Integer;
  var IsEOF: Boolean
) of Object;

property OnProgress: TProgressEvent read FOnProgress write FOnProgress;

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 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 component. When the Operation is Write (2) this value may be queried to determine when all data has been processed.

Status Event (XMLEncrypt Component)

Provides information about the current operation.

Syntax

type TStatusEvent = procedure (
  Sender: TObject;
  const Message: String
) of Object;

property OnStatus: TStatusEvent read FOnStatus write FOnStatus;

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.

XMLEncryptedDataDetail Type

This type defines details about the data to be encrypted.

Remarks

This type defines details about the data to be encrypted. The element to encrypt is defined by XMLElement.

Fields

Id
String

Default Value: ""

This property is an optional identifier for the encrypted data.

MIMEType
String

Default Value: ""

This property specifies the MIME type of the encrypted data. For example: "image/png". This property is optional.

Scope
TipcScopes

Default Value: 0

This property specifies the scope of the encryption. When calling Encrypt the entire XML element specified by XMLElement may be encrypted, or only the content may be encrypted. This setting controls the scope of the encryption. Possible values are:

0 (sElement - default) The entire XML element is encrypted.
1 (sContent) Only the content of the XML element is encrypted.

XMLElement
String

Default Value: "/"

This property specifies the XPath to the element which will be encrypted. For instance:

/root/myElement XPath syntax
/root/[1] XPath syntax using an index
/root/ns:myElement XPath syntax where the element has a namespace
myElement Just the element name
@id=myid Attribute selector: This will select an element with an attribute "id" whose value is "myid".
/root/myElement[1]/ns:name2[@attr=attrValue] XPath syntax using an index and attribute selector

Constructors

constructor Create();

Config Settings (XMLEncrypt 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 method.

XMLEnc Config Settings

DecryptWithCryptoAPI:   Whether to use the Crypto API for decrypt operations.

This setting determines whether to use the Microsoft Crypto API to decrypt. This is helpful in cases where the certificate is present in the Windows Certificate Store but the private key is not marked as exportable. For instance when using a USB security key. The default value is False.

Note: This functionality is only available on Windows.

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"

Note: This setting is not applicable when 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 and OAEPMGF1HashAlgorithm values. In this case the 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 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 component 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 component 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.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).
