The Cedato macro encryption uses a symmetric key algorithm. It uses an encryption key for the encryption and decryption of the relevant values, while authenticating the received data. For this purpose, use the key generated using the Cedato Dashboard. You can find it under the Network Settings->Encryption Key tab. The encryption mechanism uses the AES-128 cipher in CBC mode and Base64 encoding to provide delivery via URL.
