问题 I am using AndroidKeystore to generate RSA Keypair and doing encryption and decryption using this keypair My keypair generation code looks like this var keypairGen:KeyPairGenerator = KeyPairGenerator.getInstance(KeyProperties.KEY_ALGORITHM_RSA, "AndroidKeyStore") var keyPairGeneratorSpec: KeyGenParameterSpec = KeyGenParameterSpec .Builder(this.Key_Name, KeyProperties.PURPOSE_ENCRYPT or KeyProperties.PURPOSE_DECRYPT) .setDigests(KeyProperties.DIGEST_SHA256, KeyProperties.DIGEST_SHA512)

问题 I'm using google drive api in my app which works fine on both debug and release builds when I install it using .apk file. But if I publish the same release .apk on playstore and then download it from there I can't sign in to Google.

问题 I am performing an experiment: using Android keystore in a command-line Java application. I have an Activity hello world example of the keystore: https://github.com/phanirajabhandari/android-keystore-example I have just converted private method getKeyStore() in EncryptionUtils and added a single line on MainActivity, to print the getKeyStore(). The MainActivity is as follows: public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) {

问题 Android API 28 running on a Pixel 3 gives the option to require User Presence for keys generated inside the Android KeyStore. But how do I actually test for user presence when creating a signature with that key? Am I missing something in the docs? KeyGenParameterSpec.Builder keyGenSpec = new KeyGenParameterSpec.Builder("alias", KeyProperties.PURPOSE_SIGN) .setDigests(KeyProperties.DIGEST_SHA256) .setKeySize(256) .setIsStrongBoxBacked(true) .setUserPresenceRequired(true); KeyPairGenerator

问题 I lost my keystore after updating Android Studio (I searched everywhere on my machine.) Now I want to avoid losing days making a request for a new Key to Google's support. I found that I still have the initial private_key.pepk, and distribution/upload certificates (.der) as well as the keystore passwords and Alias. Is it possible to regenerate a valid keystore from these information, to sign an APK? 回答1: Are you using Android Studio? If so, then you should be able to generate a new keystore
