Decrypt given data previously encoded with aria-256-cbc cipher algo. ARIA with a 256-bit key in CBC (Cipher Block Chaining) mode. Developed as part of South Korea's national cryptographic standards. Considered secure with a 256-bit key size, offering high encryption strength. 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.
