Decrypt given data previously encoded with aria-128-cfb8 cipher algo. ARIA with 128-bit key in CFB-8 mode, encrypting one byte at a time. Similar to CFB1 but operating at the byte level. Secure but inefficient for most applications. 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.
