+**Usage:**
+
+```python
+int_cipher_text, signature = build_address_input_text(plaintext, user_aes_key, sender, contract, func_selector, signing_key)

+- `user_aes_key`: The user's AES key.
+- `sender`: The sender's address.
+- `contract`: The contract address.
+- `func_selector`: The function selector.
+- `signing_key`: The private key used for signing.
