Data encryption

Cryptography that transforms plaintext into unreadable ciphertext using an algorithm and a key: securing data at rest and in transit.

Data encryption is the core process for information security, rendering sensitive data unusable without the correct key. The technology employs two primary methods: symmetric (like AES-256) and asymmetric (like RSA). Symmetric algorithms use a single key for both encryption and decryption, offering rapid performance for bulk data. Asymmetric algorithms use a public/private key pair, primarily for secure key exchange and digital signatures. Correct implementation is non-negotiable, ensuring compliance and robust protection against unauthorized access across all storage and network layers.
