A shared secret key
and other words;
Both the sender and receiver share the same key
Symmetric key encryption is also called secret key encryption. In this method, the same key is used for both encryption and decryption, meaning that both the sender and recipient must securely share and maintain this key. This type of encryption is efficient for processing large amounts of data but requires secure key management to prevent unauthorized access.
DES
Encryption with a 48-bit key involves using a specific algorithm to scramble the data into a code that can only be deciphered with the correct key. The key, which is 48 bits long, determines how the data is encrypted and decrypted. The longer the key, the more secure the encryption, as there are more possible combinations to crack.
The asymmetric key algorithms are used to create a mathematically related key pair: a secret private keyand a published public key.
Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
A shared secret key.
A shared secret key
In symmetric key techniques there is a single key and that key is kept secret. Symmetric key is a like a sub part of classical encryption.
A: Symmetric
Symmetric encryption requires that both parties (sender and receiver) know and have the exact same encryption key. This key is used both for encrypting and decrypting the data. Using the same encryption algorithm means that only those individuals that know or have the same key will be able to read any messages encrypted by the symmetric key.
Symmetric encryption requires one key known by both parties. Asymmetric encryption uses two keys, one encryption key known publicly and one decryption key known only by the recipient.Or more simply put,YesA public and private key

This type of encryption is efficient for processing large amounts of data but requires secure key management to prevent unauthorized access.
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
The term "symmetric encryption" refers to a form of computerized cryptography that uses a singular encryption key to guise an electronic message so that it can be sent in a secure manner.
DES
A key is used to encipher something. The same key can be used to decipher it.
