The Role of Encryption in Data Security

Encryption is one of the most powerful tools for protecting sensitive data from unauthorized access. It transforms readable data into an unreadable format using complex algorithms, making it useless to hackers without the decryption key.

Types of Encryption:

Symmetric Encryption: Uses a single key for both encryption and decryption (e.g., AES – Advanced Encryption Standard).

Asymmetric Encryption: Uses a pair of keys (public and private) for encryption and decryption (e.g., RSA – Rivest-Shamir-Adleman).

End-to-End Encryption (E2EE): Ensures that data remains encrypted throughout transmission, commonly used in messaging apps like WhatsApp and Signal.

Why Encryption Matters:

Protects sensitive financial and personal information from cybercriminals.

Ensures compliance with data protection laws.

Secures communication channels, preventing eavesdropping and data leaks.

Encryption should be a standard security practice for businesses and individuals handling sensitive data.
