What is a symmetric key and what are its advantages and disadvantages?

What will be an ideal response?


Symmetric keys (also known as secret keys) use the same key to encrypt and decrypt the data. Anyone with the key can decode the data. This may be a problem when transferring data over the Internet or other networks because both the key and the encrypted data are being transferred. It is, however, the most commonly used form of encryption for protecting or storing data as it offers much better performance than asymmetric encryption.
