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.
