Android 9 - KeyStore exception android.os.ServiceSpecificException
提问by phnmnn
If I run this code on Android 9, I receive the follow exception:
如果我在 Android 9 上运行此代码，则会收到以下异常：
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;
}
}
Exception:

Please help to fix it.
请帮助修复它。

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.
最后我找到了解决方案。看起来因为 Android P(KeyStore.PrivateKeyEntry) keyStore.getEntry("alias", null)不是获取私钥的正确方法。
I was able to get rid of this warning by accessing private/public key this way
我能够通过这种方式访问私钥/公钥来摆脱这个警告
KeyStore keyStore = KeyStore.getInstance("AndroidKeyStore");
keyStore.load(null);
PrivateKey privateKey = (PrivateKey) keyStore.getKey("alias", null);
PublicKey publicKey = keyStore.getCertificate("alias").getPublicKey();

I had the same problem retrieving an asymmetricKey from AndroidKeyStore
我有同样的问题从检索非对称密钥 AndroidKeyStore
My solution based on Dr Glass answer to get keys is the following: (aliasKey is your alias string)
我基于 Dr Glass 的答案获取密钥的解决方案如下：（aliasKey 是您的别名字符串）
PublicKey:
公钥：
val keyStore = KeyStore.getInstance("AndroidKeyStore")
keyStore.load(null)
val asymmetricPublicKey = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
keyStore.getCertificate(aliasKey).publicKey
} else {
val asymmetricKey = keyStore.getEntry(aliasKey, null) as KeyStore.PrivateKeyEntry
asymmetricKey.certificate.publicKey
}
PrivateKey:
私钥：
val keyStore = KeyStore.getInstance("AndroidKeyStore")
keyStore.load(null)
val asymmetricPrivateKey = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
keyStore.getKey(aliasKey, null) as PrivateKey
} else {
val asymmetricKey = keyStore.getEntry(aliasKey, null) as KeyStore.PrivateKeyEntry
asymmetricKey.privateKey
}
and with this code I have no warning in the emulator and/or device with Android P
使用此代码，我在模拟器和/或 Android P 设备中没有警告

I found a solution how to remove the warning, would be great if you can test it all as well. Actually the order of calling the methods is the problem.
我找到了如何删除警告的解决方案，如果您也可以对其进行测试，那就太好了。实际上调用方法的顺序是问题所在。
val privateKey = keyStore.getKey(alias, null)
val publicKey = if (privateKey != null) keyStore.getCertificate(alias).publicKey else null
if (privateKey != null && publicKey != null) {
KeyPair(publicKey, privateKey as PrivateKey)
}
This is the correct ordering of how to call the methods.
这是如何调用方法的正确顺序。
When you do it like this:
当你这样做时：
val privateKey = keyStore.getKey(alias, null)
val certificate = keyStore.getCertificate(alias)
if (privateKey != null && certificate != null) {
KeyPair(certificate.publicKey, privateKey as PrivateKey)
}
You will receive the following warning (because of keyStore.getCertificate(alias):
您将收到以下警告（由于 keyStore.getCertificate(alias)）：
KeyStore exception
android.os.ServiceSpecificException: (code 7)
at android.os.Parcel.createException(Parcel.java:2085)
at android.os.Parcel.readException(Parcel.java:2039)
at android.os.Parcel.readException(Parcel.java:1987)
at android.security.keystore.IKeystoreService$Stub$Proxy.get(IKeystoreService.java:978)
at android.security.KeyStore.get(KeyStore.java:236)
at android.security.KeyStore.get(KeyStore.java:225)
at android.security.keystore.AndroidKeyStoreSpi.engineGetCertificate(AndroidKeyStoreSpi.java:160)
at java.security.KeyStore.getCertificate(KeyStore.java:1120)
This means, that there is no private key and you should first create and store a keypair beforeyou search for it in the key store.
这意味着，没有私钥，您应该先创建并存储一个密钥对，然后再在密钥库中搜索它。
Now with the answer of MatPag it should look like this:
现在有了 MatPag 的答案，它应该是这样的：
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
val privateKey = keyStore.getKey(alias, null)
val publicKey = if (privateKey != null) keyStore.getCertificate(alias).publicKey else null
return if (privateKey != null && publicKey != null) {
KeyPair(publicKey, privateKey as PrivateKey)
} else {
null
}
} else {
val asymmetricKey = keyStore.getEntry(alias, null) as KeyStore.PrivateKeyEntry
val privateKey = asymmetricKey.privateKey
val publicKey = if(privateKey != null) asymmetricKey.certificate.publicKey else null
return if(privateKey != null && publicKey != null) {
KeyPair(publicKey, privateKey as PrivateKey)
} else {
null
}
}
