XML Encryption (Password)

This adapter encrypts or decrypts any XML document according to the W3C standard XML-Encryption (XML-Enc) based on a password. This adapter supports the AES encryption algorithm with 128, 192 or 256 Bit key length as well as the Triple-DES algorithm. For encryption/decryption based on a keystore, see XML Encryption (Keystore).

Properties

Operation	Defines the operation executed by the function adapter Possible values: `Encrypt`: Encrypt input XML document `Decrypt`: Decrypt input XML document
Adapter	Main adapter class (do not change!) Possible values: de.softproject.integration.adapter.xml.encryption.XmlEncryption: Main class (Default)
method	Algorithm used for encryption/decryption Possible values: `AES_128`: Use AES algorithm with 128 Bit key length `AES_192`: Use AES algorithm with 192 Bit key length `AES_256`: Use AES algorithm with 256 Bit key length `TRIPLEDES`: Use Triple-DES algorithm
xpath	Path to the element(s) to be encrypted/decrypted addressed using an XPath expression Possible values: Any valid XPath expression, e.g. `//Data`
scope	Defines the encryption scope within the XML document structure that matches the XPath expression `Element`: Encrypt the whole element `Content`: Encrypt only the element content
password	Password for encryption/decryption Possible values: Any string

Status values

-1 (error)

An error occurred during the adapter's execution (see X4 Server log).

In case of an error, this adapters also outputs a text file that contains the corresponding exception.

0 (empty)

Document has not been changed. No matching elements were found.

1 (successful)

Document has been processed, and all matching elements have been encrypted/decrypted.

Example

In the following XML document, all Data elements are to be encrypted using XML-Encryption with the AES128 algorithm:

Input

XML

<RootElement>
  <Data>Hello</Data>
  <Data>World!</Data>
  <Public>© SoftProject GmbH</Public>
</RootElement>

As an example, the adapter returns the following encrypted result XML document:

Result
