Cryptography is very important in keeping data safe and trustworthy. It uses special methods to protect information so that only the right people can read or change it. The main purpose of cryptography is to make sure that data stays private, accurate, and secure while being stored or sent over a network.

One of the key uses of cryptography is encryption, which changes readable data into a secret code. Only someone with the correct key can unlock and read it. This protects sensitive information such as passwords, credit card numbers, and company files from hackers. Another use is digital signatures, which help confirm that a message or document really came from a trusted sender and was not changed.

Cryptography also supports data integrity by detecting any unauthorized changes. Whether used in emails, online banking, or cloud storage, cryptography builds trust and keeps personal and business data safe from cyber threats.
