Encryption: Protecting Data in Transit and at Rest
Encryption is the process of converting data into a code to prevent unauthorized access. It is one of the most effective ways to protect sensitive data, whether it’s stored on a device or transmitted over the internet. There are two primary types of encryption:
Symmetric Encryption: Both the sender and receiver use the same key to encrypt and decrypt data. AES (Advanced Encryption Standard) is one of the most widely used symmetric encryption algorithms.
Asymmetric Encryption: Involves two keys: a public key for encryption and a private key for decryption. RSA and ECC (Elliptic Curve Cryptography) are commonly used asymmetric encryption algorithms.
Encryption ensures that even if attackers intercept data, they won’t be able to read or manipulate it without the appropriate decryption keys.
