Cryptography is a method used to protect data by converting it into a secret form so that only authorized users can access or understand it. This method is valuable because it ensures the integrity, confidentiality, and authenticity of information, which are crucial in today’s digital world. By using cryptography, sensitive data—such as passwords, bank transactions, and private communications—can be kept secure from unauthorized access and tampering. One key application is in verifying the integrity of data. Digital signatures, for example, help ensure that the information hasn’t been altered during transmission. If someone tries to change the data, the digital signature will no longer match, indicating a potential security breach. Overall, cryptography plays a critical role in protecting personal and organizational data from cyberattacks, ensuring that sensitive information remains private and trustworthy. It builds trust in digital systems, making it essential for online activities like banking, shopping, and communications.
