Encryption is the process of converting data or information into a coded format that can only be accessed or read by authorized users with the correct decryption key. It is a fundamental technique used to protect sensitive data from unauthorized access, cyberattacks, and identity theft.
Encryption is widely used in online banking, email communications, cloud storage, messaging apps, and secure websites. It ensures that even if data is intercepted, it remains unreadable and secure.
There are two main types of encryption:
Symmetric Encryption: Uses a single key for both encryption and decryption. Examples include AES (Advanced Encryption Standard).
Asymmetric Encryption: Uses a pair of keys—a public key to encrypt data and a private key to decrypt it. Examples include RSA (Rivest-Shamir-Adleman).
Encryption works in conjunction with other cybersecurity measures, such as authentication and secure protocols like HTTPS, to provide comprehensive protection for digital communications and stored data.
