Symmetric Key

+**Symmetric Key**

+Symmetric-key encryption employs a single, shared [Secret Key](/wiki/secret_key) for both encrypting and decrypting data. This method allows for swift, private communication, as long as the key is securely exchanged and remains known only to the intended parties, contrasting with [Public Key](/wiki/public_key) cryptography.
