algorithm identifier 1.2.840.10045.2.1 in key not recognised

[mahermeg17]

Hi,
need to convert pkcs8 to pkcs12 so I used this code to load privatekey from pkcs8 file :

public static PrivateKey loadPrivateKey(String keyFile) { try { File f = new File(keyFile); FileInputStream fis = null; fis = new FileInputStream(f); DataInputStream dis = new DataInputStream(fis); byte[] keyBytes = new byte[(int) f.length()]; dis.readFully(keyBytes); dis.close(); PKCS8EncodedKeySpec spec = new PKCS8EncodedKeySpec(keyBytes); KeyFactory kf = KeyFactory.getInstance("RSA"); PrivateKey pk = kf.generatePrivate(spec); return pk; } catch (FileNotFoundException e) { e.printStackTrace(); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (InvalidKeySpecException e) { e.printStackTrace(); } return null; }

but I have an exception org.spongycastle.jcajce.provider.asymmetric.util.ExtendedInvalidKeySpecException

org.spongycastle.jcajce.provider.asymmetric.util.ExtendedInvalidKeySpecException: unable to process key spec: java.io.IOException: algorithm identifier 1.2.840.10045.2.1 in key not recognised at org.spongycastle.jcajce.provider.asymmetric.rsa.KeyFactorySpi.engineGeneratePrivate(KeyFactorySpi.java:105) at java.security.KeyFactory.generatePrivate(KeyFactory.java:186) at org.XXXXXX.loadPrivateKey(CertProvider.java:45) at android.app.Activity.performCreate(Activity.java:5104) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1080) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2144) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2230) at android.app.ActivityThread.access$600(ActivityThread.java:141) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1234) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:5041) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:793) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:560) at dalvik.system.NativeStart.main(Native Method) Caused by: java.io.IOException: algorithm identifier 1.2.840.10045.2.1 in key not recognised at org.spongycastle.jcajce.provider.asymmetric.rsa.KeyFactorySpi.generatePrivate(KeyFactorySpi.java:153) at org.spongycastle.jcajce.provider.asymmetric.rsa.KeyFactorySpi.engineGeneratePrivate(KeyFactorySpi.java:91) ... 17 more

any indication to solve this? or may SC on android can handle *.pkcs8, so I don't need to convert to pkcs12 (at least for this momment I just need *.pkcs8 files).
