问题 I cannot obtain a (private) key from KeyStore on Android. Problem occurs mainly on Samsung devices (S6, S6 Edge) and Android 6. android.security.KeyStoreException: Invalid key blob is thrown when following line is called (where alias is name for store key). KeyStore.PrivateKeyEntry privateKeyEntry = (KeyStore.PrivateKeyEntry)keyStore.getEntry(alias, null); The KeyStore itself is obtained by KeyStore.getInstance("AndroidKeyStore"); And key is generated by the following method: private static

问题 I'm attempting to write a few testcases that work against the Android Keystore. However, when I write the following test case: @RunWith(RobolectricGradleTestRunner.class) @Config(constants = BuildConfig.class, sdk = 21) public class FancyPantsUnitTest { @Test public void buildKey() { keyPairGenerator = KeyPairGenerator.getInstance("RSA", "AndroidKeyStore"); keyPairGenerator.initialize(4096); final KeyPair keyPair = keyPairGenerator.generateKeyPair(); } } This fails with the following

问题 In newer versions of Android (I guess since 4.2) there is an option called "hardware-backed" and "software only". As Google supposes: Android also now supports hardware-backed storage for your KeyChain credentials, providing more security by making the keys unavailable for extraction. That is, once keys are in a hardware-backed key store (Secure Element, TPM, or TrustZone) , they can be used for cryptographic operations but the private key material cannot be exported. Even the OS kernel

问题 I am using Ionic 2 with GooglePlus Authentication. Everything works perfectly for iOS . For Android I build my app as follows: ionic build android For the Android build, I need a SHA1 keystore for Google Authentication. I have a Macintosh HD/Users/myname/.android/debug.keystore , so according to these instructions, I generate a keystore using (default password ' android '): keytool -exportcert -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore The output looks correct. I use

问题 I'm developping an Android App that generates an EC Asymetric key. When my app gets connected to a device, they exchange their public key. They then use ECDH to establish a shared secret. This shared secret is then used to derive an AES session key. All this is working fine. I'm now working on the storage of the asymetric key. I wanted to put it in the Android KeyStore but I don't see how I can then do the ECDH operation. The key in the key store can be used to sign, decrypt or encrypt but I

问题 I have created an application and published on android market. now i want to publish its 2nd version. the few thing i want to make clear: I have kept same package name. I do not have previous keystore cause i changed the windows so keystore deleted and i do not have backup of that keystore.

问题 I'm following guideline how to sign Android apk with Jenkins. I have parametrized Jenkins job with KSTOREPWD and KEYPWD. A part of Jenkins' job configuration (Build->Execute shell) is to take those parameters and store them as environment variables: export KSTOREPWD=${KSTOREPWD} export KEYPWD=${KEYPWD} ... ./gradlew assembleRelease The problem is when the build is over anybody can access the build "Console Output" and see what passwords were entered; part of that output: 08:06:57 + export
