WebMar 15, 2024 · There are two main types of encryption systems: symmetric encryption and asymmetric encryption. Here’s how they’re different. Symmetric encryption uses a single password to encrypt and decrypt data. Asymmetric encryption uses two keys for encryption and decryption. A public key, which is shared among users, encrypts the data. WebCryptography (or cryptology; from Greek κρυπτός, kryptos, "hidden, secret"; and γράφ, gráph, "writing", or -λογία, -logia, respectively) is the practice and study of hiding information.
