For the DESEncryption or DESDecryption client actions to function, the DES Script must be explicitly referenced in the Scope.

How to add the Script:

1. In Service Studio, navigate to the Interface tab.
2. Select the Screen or Block where you are calling the DES actions.
3. In the Properties pane, locate the Scripts folder/property.
4. Right-click and select Add Required Script.
5. Select the DES script from the component's library.

[!CAUTION]

Runtime Error: If this script is missing, the client actions will fail to initialize the cryptographic library, resulting in a "ReferenceError: DES is not defined" in the browser console.

3. Client Actions Reference

A. DESEncryption

Used to secure sensitive data before storage or transmission.

• Inputs:
  • Plaintext: The string to be encrypted.
  • SecretKey: A 64-bit symmetric key.
• Outputs:
  • Ciphertext: The resulting encrypted string (Base64).

B. DESDecryption

Used to retrieve original data from a secured string.

• Inputs:
  • Ciphertext: The encrypted Base64 string.
  • SecretKey: The same 64-bit key used for encryption.
• Outputs:
  • DecryptedResult: The original plaintext (e.g., PROJECT ZERO ALPHA).

5. Demo & Testing

You can verify the logic and UI implementation by visiting the Symmetric DES Engine Demo. The demo showcases the Plug & Play Script Architecture and the parameter-driven sample data workflow.
