Cryptography is the practice of securing information by transforming it into a code that is difficult to understand without the correct key or method to decode it. It involves creating and using techniques to ensure that messages and data remain confidential and protected from unauthorized access. Cryptography is commonly used to protect sensitive information, such as personal communications and financial transactions, by encoding it in a way that only authorized individuals can read or interpret.
