| Password Check With State Machine |
Great crackme! Reverse engineering Rust binaries is always a fun challenge due to the massive amount of noise the compiler generates.
The biggest struggle was definitely fighting through the headless analysis and static decompilation to clean up the noise and find the true logic. Once the 'process_bytes' function was isolated and the state machine's register optimization layout became clear, tracking the state transitions and decoding the correct constraints was a brilliant puzzle to solve.
Thanks for sharing this, looking forward to more of your challenges!
