Question

What type of key is used in symmetric cryptography, must be known by both parties, and is used for both encryption and decryption?

Answer 1

A form of encryption known as symmetric encryption uses a single secret key to both encrypt and decrypt electronic data.

What is symmetric cryptography?

In symmetric cryptography, also called secret key cryptography, parties exchange encrypted data using a single shared secret. Because you use the same key to encrypt and decode the data, symmetric ciphers fall under this category.

What do you mean by secret key?

When a cryptographic method is applied to a piece of data, often a string of numbers or letters that is saved in a file, the result is a key that may be used to encode or decode cryptographic data.

A cryptographic variable used with an algorithm to encrypt and decrypt data is called a private key, also referred to as a secret key. Only those parties who have been given permission to decode the data and the key generator should have access to secret keys.
