Decrypt given data previously encoded with aria-192-ofb cipher algo. ARIA in OFB (Output Feedback) mode is a stream cipher variant of the ARIA cipher. Part of the ARIA suite developed for South Korean standards. Secure, but slower compared to other modes like CTR. 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.
