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("");

    }
