I asked AI about my code to solve my API key problem which is an ecrypted json file for the api key stored on google and then downloaded locally it said:

This code uses a salted password-based key derivation function (PBKDF2) with 100,000 iterations to generate a key for AES-256 in Galois/Counter Mode (GCM). In modern cryptography, AES-256 is widely regarded as secure when implemented correctly, especially in GCM mode, which provides both confidentiality and integrity checks [[1]]. Moreover, employing a sufficiently large iteration count (e.g., 100,000) significantly hardens the key against brute-force or dictionary attacks by increasing the time required for each guess.
