Android 应用程序登录屏幕 - 错误的变量和共享首选项比较

Question

我正在尝试将加密密码存储在我的应用程序的 SharedPreferences 中。根据日志密码正确保存并在加密后匹配键入的密码，但在比较中它们不相等。每次它运行 else 指令时。我找不到问题所在，所以我寻求帮助！顺便说一句，有什么更好、更安全的密码存储方式，甚至是加密的？public class LoginActivity extends AppCompatActivity {    private static final String PREFERENCES_NAME = "passHashed";    private static final String PREFERENCES_TEXT_FIELD = "textField";    public EditText Password;    public TextView Info;    private String passSavedHash;    private SharedPreferences preferences;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_login);        Password = (EditText) findViewById(R.id.etPassword);        Info = (TextView) findViewById(R.id.Info);        Button loginBtn = findViewById(R.id.loginButton);        preferences = getSharedPreferences(PREFERENCES_NAME, AppCompatActivity.MODE_PRIVATE);        if(!passRead().equals("0")) {            passSavedHash = passRead();            Log.d("Password", "passHashed: " + passSavedHash);        }        else{            loginBtn.setText(R.string.set_pass);        }    }    public void onClickValidate(View view) throws Exception {        String password = Password.getText().toString();        String passHash = CipherAlgorithm.encrypt(password);        Log.d("Password", "passHashed:    " + passSavedHash);        Log.d("Password", "passSavedHash: " + passHash);        if(passRead().equals("0") && password.length() > 3) {            passSave();            Intent intent = new Intent(LoginActivity.this, MainActivity.class);            startActivity(intent);        }        else {            if (Objects.equals(passSavedHash, passHash)) {                Intent intent = new Intent(LoginActivity.this, MainActivity.class);                startActivity(intent);            } else {                Info.setText(R.string.wron_pass);            }        }        Password.setText("");    }
