What is the primary difference between symmetric and asymmetric $($public$-$key$)$ cryptography? $($Select all that apply$)$

Group of answer choices

Symmetric cryptography uses a single secret key, while asymmetric cryptography uses both a secret key and a public key.

Symmetric cryptography is primarily used for digital signatures, while asymmetric cryptography is primarily used for data encryption.

Asymmetric cryptography was introduced in $1976,$ while symmetric cryptography has been in use since ancient times.

Asymmetric cryptography employs both a secret key and a public key, whereas symmetric cryptography only uses a single secret key.

Symmetric cryptography is mainly used for data encryption and integrity checks.
