### Why is symmetric encryption used?

Mostly for performance - symmetric encryption is much much faster (order of magnitudes) than asymmetric encryption.

A: Symmetric

### Symmetric encryption involves what key?

A shared secret keyand other words;Both the sender and receiver share the same key

### What does the word symmetric encryption mean?

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.

### How are classical encryption techniques like modern symmetric-key cipher?

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.

### How does symmetric key encryption work?

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.

### Which cryptographic algorithms is a symmetric encryption method?

Twofish, Advanced Encryption Standard, Blowfish, Serpent, CAST 5, RC4, TDES, and IDEA are all examples of symmetric encryption methods. In short, any algorithm that uses the same or similar cryptographic keys for encryption and decryption is a symmetric encryption method. Symmetric encryption methods are also divided into two different categories, stream ciphers and block ciphers. These two encryption methods are much like the difference between an interpreter and a compiler in programming. Stream encrypts individual bytes one at a time, while Block encrypts volumes as a whole.
