Decrypt given data previously encoded with aria-128-ecb cipher algo. ARIA with 128-bit key in ECB (Electronic Codebook) mode. A straightforward mode of ARIA but vulnerable to pattern leakage. Insecure due to lack of diffusion. 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.
