WebJul 11, 2024 · HS256 is HMAC with sha256 which is going to be computationally infeasible to brute force as long as the key is long and random enough. In this case, it's 512 bits which is sufficient given a decent pseudorandom number generator. The hexadecimal conversion is probably due to the expected input format, you can't just make it non-hexadecimal.
