Random use of this method may result in sensitive information being printed out in plaintext by the service when it should have been hidden, leading to leakage of sensitive information.If output is necessary, it is recommended to prioritize encoding before outputting (e.g., nonsensitive(sha256(var.sensitive_value)))
