**Asymmetric**algorithms use two interdependent keys, one to

**encrypt**the data, and the other to decrypt it. As RSA is much slower than

**symmetric encryption**, what typically happens is that data is

**encrypted**with a

**symmetric**algorithm and then the comparatively short

**symmetric**key is

**encrypted**using RSA.

Subsequently, one may also ask, what is the difference between symmetric and asymmetric keys?

**What is the difference between symmetric and asymmetric**encryption?

**Symmetric**encryption is strong and

**asymmetric**encryption is weak.

**Symmetric**uses one key to both encrypt and decrypt, and

**asymmetric**uses two keys.

**Symmetric**is one way, and

**asymmetric**is a two way function.

What is an asymmetric key?

**Asymmetric cryptography**, also known as

**public key cryptography**, uses

**public**and private

**keys**to encrypt and decrypt data. The

**keys**are simply large numbers that have been paired together but are not identical (

**asymmetric**). One

**key**in the pair can be shared with everyone; it is called the

**public key**.

Is AES 256 symmetric or asymmetric?

**Symmetric**key

**encryption**is a type of

**encryption**that makes use of a single key for both the

**encryption**and decryption process. Some of the

**encryption**algorithms that use

**symmetric**keys include:

**AES**(Advanced

**Encryption**Standard), Blowfish, DES (Data

**Encryption**Standard), Triple DES, Serpent, and Twofish.
