c 我已经加密和解密了存储在 Android Keystore 中的登录密码。在 Android 9 上，我观察到应用程序在尝试解密密码时崩溃（我无法重现它，但拥有 Pixel 3 的人是崩溃的设备之一）。下面是我从密钥库解密密码的方法。

private static final String TRANSFORMATION = "AES/GCM/NoPadding";
private static final String ANDROID_KEY_STORE = "AndroidKeyStore";

private KeyStore keyStore;

public Decryptor() throws CertificateException, NoSuchAlgorithmException, KeyStoreException,
        IOException {
    initKeyStore();
}

private void initKeyStore() throws KeyStoreException, CertificateException,
        NoSuchAlgorithmException, IOException {
    keyStore = KeyStore.getInstance(ANDROID_KEY_STORE);
    keyStore.load(null);
}

@TargetApi(19)
public String decryptData(final String alias, final byte[] encryptedData, final byte[] encryptionIv)
        throws UnrecoverableEntryException, NoSuchAlgorithmException, KeyStoreException,
        NoSuchProviderException, NoSuchPaddingException, InvalidKeyException, IOException,
        BadPaddingException, IllegalBlockSizeException, InvalidAlgorithmParameterException {
