Decrypt given data previously encoded with aria-128-cfb cipher algo. ARIA with 128-bit key in CFB (Cipher Feedback) mode, a stream-like encryption method. ARIA was introduced as an alternative to AES with similar security goals. Secure but susceptible to bit-flipping attacks. 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.
