Decrypt given data previously encoded with aria-192-cfb cipher algo. ARIA in CFB (Cipher Feedback) mode is a stream cipher variant using a 192-bit key. Part of the ARIA family, created for cryptographic standards in South Korea. Secure, but less efficient than AES in stream cipher mode. 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.
