### Create it { #create-it }

Create a file `main.py` with:

```Python

        byte[] originalEncKey = testEncryptionKey.clone();

        // Ensure keys are not zero initially
        assertFalse(isAllZeros(originalEncKey), "Original encryption key should not be all zeros");
        assertFalse(isAllZeros(originalDecKey), "Original decryption key should not be all zeros");

    private byte[] preauthIntegrityHash;
    private static final int SIGNATURE_OFFSET = 48;
    private static final int SIGNATURE_LENGTH = 16;

    @BeforeAll
    static void setupClass() {

        }
    }

	VersionID string `xml:"VersionId"`
