Encrypt given data using des-ede cipher algo. DES-EDE (Triple DES) applies DES encryption three times, using two or three unique keys for stronger encryption. Triple DES was introduced as a more secure alternative to DES, compensating for its short key length by applying DES multiple times. Triple DES is more secure than DES, but it is considered outdated and slower compared to modern algorithms like AES. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
