"WebSymmetric key encryption requires that all intended message recipients have access to the shared key. Therefore, a secure communication channel must be established among the participants so that the key can be transmitted to each along with the ciphertext. This presents practical problems and limits the use of direct symmetric key exchange. " - Cryptography symmetric key
