• Description: The manifest associated with the encrypted data.

payload

• Type: Uint8Array
• Description: The encrypted data as a byte array.

b64Payload

• Type: string
• Description: The encrypted data as a Base64-encoded string.

Methods

toJson()

• Description: Converts the instance to a serializable JSON object.
• Returns: A JSON object containing the metadata, Base64-encoded payload, and associated manifest.

fromJson(input)

• Description: Creates a new SdsdkZtdf instance from a JSON object.
• Parameters:
  • input: The JSON object to convert.
• Returns: A new SdsdkZtdf instance.
• Throws: SdsdkError if the input is invalid or required properties are missing.

Example Usage

const jsonData = {
  metadata: {
    version: 1,
  },
  b64payload: 'aBase64EncodedString',
  manifest: {
    // Manifest properties
  },
};

const ztdfInstance = SdsdkZtdf.fromJson(jsonData);

// Accessing instance properties
console.log(ztdfInstance.manifest);
console.log(ztdfInstance.payload);
console.log(ztdfInstance.b64Payload);

// Converting the instance to a JSON object
const jsonData2 = ztdfInstance.toJson();
console.log(jsonData2);

// Serialize into base64 data
b64OfZtdfInstance = Buffer.from(JSON.stringify(jsonData2)).toString('base64');
