Decrypt given data previously encoded with id-aes128-GCM cipher algo. AES with 128-bit key size in GCM (Galois/Counter Mode), offering authenticated encryption with excellent performance and parallelization capabilities. AES-128-GCM is used extensively in protocols like TLS and IPsec for secure data transmission and integrity verification. AES-128-GCM is very secure and efficient, widely regarded as one of the best choices 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.
