XMLEncrypt Component
Properties Methods Events Config Settings Errors
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:
- SymmetricKey (required)
- EncryptingAlgorithm
- EncryptedDataDetail*
- RecipientCert*
- 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:
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:
- SymmetricKey
- Certificate
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.

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:
- SymmetricKey
- Certificate
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:
- SymmetricKey (required)
- EncryptingAlgorithm
- EncryptedDataDetail*
- RecipientCert*
- KeyName
Input and Output Properties
The component will determine the source and destination of the input and output based on which properties are set.

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:
0 | Element |
1 | Content |
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 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:
0 | None |
1 | Read |
2 | Write |
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;
