Parameters:
(password[], salt[], ret_hash[], ret_hash_len)
password[]The password to hash.
salt[]The salt to use in the hash.
ret_hash[]The returned hash.
ret_hash_lenThe returned hash maximum length.

This function does not return any specific values.


Tips

  • The salt is appended to the end of the password, meaning password 'foo' and salt 'bar' would form 'foobar'.
  • The salt should be random, unique for each player and at least as long as the hashed password. It is to be stored alongside the actual hash in the player's account.


Example Usage: 

public OnGameModeInit()
{
    new MyHash[64 + 1]; // + 1 to account for the required null terminator
    SHA256_PassHash("test", "78sdjs86d2h", MyHash, sizeof MyHash);
    printf("Returned hash: %s", MyHash);
    return 1;
}
