Android 9-KeyStore异常android.os.ServiceSpecificException [英] Android 9 - KeyStore exception android.os.ServiceSpecificException

问题描述

如果我在Android 9上运行此代码，则会收到以下异常:

If I run this code on Android 9, I receive the follow exception:

private static KeyStore.PrivateKeyEntry getPrivateKeyEntry(String alias) {
        try {
            KeyStore ks = KeyStore
                    .getInstance(SecurityConstants.KEYSTORE_PROVIDER_ANDROID_KEYSTORE);
            ks.load(null);
            KeyStore.Entry entry = ks.getEntry(alias, null);

            if (entry == null) {
                Log.w(TAG, "No key found under alias: " + alias);
                Log.w(TAG, "Exiting signData()...");
                return null;
            }

            if (!(entry instanceof KeyStore.PrivateKeyEntry)) {
                Log.w(TAG, "Not an instance of a PrivateKeyEntry");
                Log.w(TAG, "Exiting signData()...");
                return null;
            }
            return (KeyStore.PrivateKeyEntry) entry;
        } catch (Exception e) {
            Log.e(TAG, e.getMessage(), e);
            return null;
        }
    }

例外:

请帮助修复它.

推荐答案

最后，我找到了解决方案.由于Android P (KeyStore.PrivateKeyEntry) keyStore.getEntry("alias", null)并不是获取私钥的正确方法，因此似乎.

Finally I found a solution. It looks like since Android P (KeyStore.PrivateKeyEntry) keyStore.getEntry("alias", null) is not a proper way to get private key.

我能够通过这种方式访问​​私钥/公钥来摆脱此警告

I was able to get rid of this warning by accessing private/public key this way

KeyStore keyStore = KeyStore.getInstance("AndroidKeyStore");
keyStore.load(null);

PrivateKey privateKey = (PrivateKey) keyStore.getKey("alias", null);
PublicKey publicKey = keyStore.getCertificate("alias").getPublicKey();
