Decrypt given data previously encoded with 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 Triple DES with CFB is more secure than single DES but still considered outdated due to performance concerns and the relatively short key length.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 decryption process assumes the IV string is prepended in the encoded string during the encryption process. You can not decrypt and get the correct results if the IV or passphrase mismatch occurs between encryption and decryption process.
