Symmetric-key encryption

Symmetric-key algorithm

Symmetric-key algorithms use the same cryptographic key for both encryption and decryption of data. This shared secret between two or more parties is used to maintain a private information link, but requires all parties to have access to the key. Symmetric-key encryption is usually better for bulk encryption due to its smaller key size and faster transmission. Asymmetric-key encryption is often used to exchange the secret key for symmetric-key encryption.
