Decrypt given data previously encoded with id-aes192-GCM cipher algo. AES with 192-bit key size in GCM mode, offering authenticated encryption with strong performance and parallelization capabilities. AES-192-GCM is widely used in modern cryptographic protocols like TLS and IPsec for secure communications and data integrity. AES-192-GCM is very secure and efficient, providing excellent performance for both encryption and authentication. 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.
