Encryption is the process of converting plain or readable text into coded or unreadable text in a secure manner. It is a technique of converting sensitive information or data into a form that cannot be easily understood or read by unauthorized users. Encryption uses complex mathematical algorithms and rules to transform data and makes it unreadable. To read the encrypted data, authorized users require a specific key or password. Encryption is widely used to protect sensitive data, such as financial information, personal information, and login credentials during data transmission and storage. By securing the information, encryption helps to prevent unauthorized access, theft, or interception by cybercriminals and other malicious actors.
