Encrypt given data using des-ede-cfb cipher algo. Triple DES (DES-EDE) in CFB (Cipher Feedback) mode, applying DES three times with feedback for encryption of smaller data units. Triple DES was introduced to provide stronger encryption than DES, and CFB mode was chosen for its ability to handle smaller blocks of data. Triple DES with CFB is more secure than single DES but still considered outdated due to performance concerns and the relatively short key length. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
