Encryption is a process of converting information or data into a code or cipher to protect it from unauthorized access. It is a fundamental security measure used in various applications, such as secure communication, data storage, and online transactions. Encryption ensures that even if data is intercepted, it remains unreadable without the proper decryption key.
The use of encryption is widespread in securing online activities, from HTTPS (SSL/TLS encryption for web traffic) to encrypting sensitive files on a computer. For example, when you log in to your online banking account, your username and password are transmitted securely via encryption, ensuring the confidentiality of your login information.
