What tools can be used to debug 'error iv' issues in code?

Debugging 'error iv' issues often involves logging the IV values used during encryption and decryption. Tools like debuggers (GDB, Visual Studio Debugger) can help step through the code and inspect the IV. Network analysis tools (Wireshark) can be useful if the IV is being transmitted as part of the encrypted data. Code analysis tools can also help identify potential IV reuse vulnerabilities.
