Symmetric Encryption: secure data using a single shared key for both encryption and decryption.

Symmetric Encryption

Symmetric encryption is a type of encryption where the same key is used for both encryption and decryption of data.

This means that the sender and receiver must have a shared secret key that is used to encrypt and decrypt the data.

Symmetric encryption is commonly used for securing sensitive data such as passwords, credit card numbers, and other confidential information.

The process of symmetric encryption involves taking plaintext data and using an encryption algorithm and a secret key to transform the data into ciphertext.

The ciphertext can then be sent over a network or stored in a database, and can only be decrypted by someone who has the secret key.

This makes symmetric encryption a secure way to protect data from unauthorized access.

Some popular symmetric encryption algorithms include AES (Advanced Encryption Standard), DES (Data Encryption Standard), and 3DES (Triple Data Encryption Standard).

These algorithms use different key lengths and encryption techniques to provide varying levels of security.
