WebbJWT cracker A multi-threaded JWT brute-force cracker written in C. If you are very lucky or have a huge computing power, this program should find the secret key of a JWT token, allowing you to forge valid tokens. This is for testing purposes only, do not put yourself in trouble :) I used the Apple Base64 implementation that I modified slightly. WebbThe implementation of JWT is very crucial for the safety of an API. Another important factor is the strength of the secret key used for signing the tokens. This challenge is all about bruteforcing the weak JWT secret key used by the REST API. Objective: Determine the secret key and leverage it to read the flag stored on the target server.

Webb11 juli 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 … Webb18 maj 2024 · Brute Force JWT token. Author: Marco Brotto.
