我们目前遇到的问题是,当用户安装我们的应用程序时,应用程序会尝试访问并在密钥库中生成密钥,但密钥库会抛出此异常:

Caused by: java.lang.IllegalStateException: could not generate key in keystore
        at android.security.AndroidKeyPairGenerator.generateKeyPair(AndroidKeyPairGenerator.java:100)
        at java.security.KeyPairGenerator$KeyPairGeneratorImpl.generateKeyPair(KeyPairGenerator.java:275)

我们认为它与手机上的解锁模式有关,无法解锁密钥库,和/或设备管理员锁定密钥库.

这是密钥库的创建方式以及密钥的生成方式:

public SecretKeyWrapper(Context context, String alias) throws GeneralSecurityException, IOException {
    mCipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
    final KeyStore keyStore = KeyStore.getInstance("AndroidKeyStore");
    keyStore.load(null);

    if (!keyStore.containsAlias(alias)) {
        generateKeyPair(context, alias);
    }

    final KeyStore.PrivateKeyEntry entry = (KeyStore.PrivateKeyEntry) keyStore.getEntry(alias, null);
    mPair = new KeyPair(entry.getCertificate().getPublicKey(), entry.getPrivateKey());
}

private static void generateKeyPair(Context context, String alias) throws GeneralSecurityException {
    final Calendar start = new GregorianCalendar();
    final Calendar end = new GregorianCalendar();
    end.add(Calendar.YEAR, 100);
