Decrypt given data previously encoded with aria-192-gcm cipher algo. ARIA with GCM (Galois/Counter Mode) provides both encryption and data integrity checks, commonly used in modern systems. Part of ARIA's development for secure encryption and integrity. Very secure, widely used in secure protocols like TLS and IPsec. 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.
