What is Encryption?
Encryption transforms readable data (plaintext) into an unreadable format (ciphertext) using mathematical algorithms and keys. Two main types exist: symmetric encryption (same key for encryption and decryption, like AES) and asymmetric encryption (public/private key pairs, like RSA). Encryption protects data at rest (stored on disk), in transit (moving over networks via TLS), and in use. It is fundamental to secure communications, data protection, and regulatory compliance.
