Symmetric key establishment is a fundamental concept in cybersecurity that plays a crucial role in ensuring the confidentiality, integrity, and authenticity of data transmission. It involves the secure exchange of cryptographic keys between two or more entities to establish a shared secret key for encryption and decryption purposes. This process is essential for maintaining secure

The process of decrypting a ciphertext using the Data Encryption Standard (DES) algorithm involves several steps that are essential for recovering the original plaintext. DES is a symmetric key block cipher, meaning that the same key is used for both encryption and decryption. The decryption process is essentially the reverse of the encryption process, and
