Decrypt given data previously encoded with aes-192-gcm cipher algo. AES with 192-bit key in Galois/Counter Mode (GCM), providing both encryption and authentication. Developed for high-performance encryption with integrity checks, widely used in TLS and secure communications. Highly secure when used with proper IV management, making it a preferred mode for authenticated encryption. 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.
