Decrypt given data previously encoded with aria-192-ctr cipher algo. ARIA in CTR (Counter) mode is a block cipher mode that turns ARIA into a stream cipher. Part of ARIA's official suite of modes. Considered secure, but performance may vary depending on implementation. 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.
