Decrypt given data previously encoded with aria-128-ofb cipher algo. ARIA with 128-bit key in OFB (Output Feedback) mode. Transforms ARIA into a stream cipher. Secure but vulnerable 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.
