WebFeb 8, 2024 · For SHA-256 hash it is impossible to find neither the preimage (the real password) nor the second preimage (some other password that produces the same hash). Thus the only way to attack is brute-forcing. The space of SHA-256 hashes is much bigger than the space of MD5 hashes. WebThe hashing function is run against the salt concatenated along with the password and then the salt is concatenated again with the resulting hash from the function and that string is what is stored in the password database like /etc/shadow.
