Decrypt given data previously encoded with aria128 cipher algo. ARIA with a 128-bit key. A variant of the ARIA cipher with a smaller key size. Developed as a part of South Korea’s cryptographic standards. Less secure compared to 192-bit and 256-bit ARIA variants. 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.
