Symmetric cryptography and asymmetric cryptography are two types of encryption techniques used in cryptography. In symmetric cryptography, the same key is used for encryption and decryption. It is fast, but the key must be shared between the sender and receiver, making it vulnerable to attacks if the key is intercepted. In contrast, asymmetric cryptography, also known as public-key cryptography, uses two keys for encryption and decryption. The public key is used for encryption, and the private key is used for decryption. This makes it more secure, but slower compared to symmetric cryptography.[/b]
