使用指纹密码时,创建密钥的时候,原代码如下:
/** * 创建密钥 * invalidatedByBiometricEnrollment是false的话,录入新的指纹创建的密钥不会失效 * 默认是true,true的话,注册新指纹,密钥将失效 * 7.0以上的系统这个参数才有效 */ public void createKey(boolean invalidatedByBiometricEnrollment) { try { mKeyStore.load(null); final KeyGenerator generator = KeyGenerator.getInstance(KeyProperties.KEY_ALGORITHM_AES, "AndroidKeyStore"); final int purpose = KeyProperties.PURPOSE_ENCRYPT | KeyProperties.PURPOSE_DECRYPT; final KeyGenParameterSpec.Builder builder = new KeyGenParameterSpec.Builder(AppParam.getInstance().getKeyName(), purpose); builder.setBlockModes(KeyProperties.BLOCK_MODE_CBC); builder.setUserAuthenticationRequired(true);//每次使用这个密钥,需要指纹验证 builder.setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_PKCS7); //添加这个会报错:android.security.KeyStoreException: Key user not authenticated // if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { // builder.setInvalidatedByBiometricEnrollment(invalidatedByBiometricEnrollment); // } generator.init(builder.build()); generator.generateKey(); } catch (Exception e) { throw new RuntimeException(e); } }我在魅蓝E(安卓7.0)的手机上测试的时候,添加上面那个条件,不是像demo写那样,判断录入新指纹,而是报错
android.security.KeyStoreException: Key user not authenticated
找了好久的问题才找到。
