Symmetric Key Cryptography:
Symmetric key cryptography, also known as secret key cryptography, is a cryptographic method where the same key is used for both encryption and decryption of the message. In this approach, the communicating parties share a common secret key, and this key is kept confidential between them. The primary goal of symmetric key cryptography is to ensure secure communication by keeping the key secret and using it to protect the confidentiality and integrity of the transmitted data.
