If you use one key to encrypt and decrypt data, then it means you’re using symmetric encryption. But if you’re using two separate keys — one to encrypt data and the other to decrypt it — then you’re using asymmetric encryption (public key encryption). great wall chinese restaurant bradford paWeb1.Symmetric Encryption: Symmetric encryption is a type of encryption where the same secret key is used for both encryption and decryption of data. It is also known as shared-key or secret-key encryption. The sender and receiver both use the same key to encrypt and decrypt the data. great wall chinese restaurant bowling green

"WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used. " - Cryptogrophy what is composite key
