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 can be broken down into three different types: Secret Key Cryptography; Public Key Cryptography; Hash Functions; Secret Key Cryptography, or symmetric cryptography, uses a single key to encrypt data. Both encryption and decryption in symmetric cryptography use the same key, making this the easiest form of cryptography. … dictionary\u0027s jx
