Encrypt given data using desx cipher algo. DES-X is an enhanced version of DES, using key whitening techniques to improve its security by adding additional bits to the DES algorithm. DES-X was introduced as an attempt to strengthen DES by mitigating its vulnerability to brute-force attacks by expanding the key space. Although more secure than DES, DES-X is still considered vulnerable due to the short key size and its reliance on the aging DES algorithm. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
