bouncycastle - Android bouncy castle: IOException

Question

I am using Sun's keytool to create a Bouncy castle keystore and import a certificate into it. The keytool does produce a keystore in the Bouncy castle format.

I then attempt to import the Bouncy castle keystore into an Android program. I am able to get an instance of the "BKS" keystore but calling load on the keystore throws

"java.io.IOException: Wrong version of key store".

This is the code

KeyStore keyStore = KeyStore.getInstance("BKS");
InputStream is = new FileInputStream("/mnt/sdcard/ArcGIS/mystore.bks");
keyStore.load(is, "abcdef".toCharArray());

I tried various versions of the Bouncy castle JAR downloaded from http://www.bouncycastle.org/latest_releases.html

What am I doing wrong?

Thanks, Ranjit

It seems the version of BouncyCastle shipped with Android 4.0.3 (API version 15) fails when trying to open keystores produced using the most recent BouncyCastle library. When I created a keystore using bcprov-jdk15on-147.jar, my sample Android app failed with the java.io.IOException: Wrong version of key store error.

However, if the keystore was created with the bcprov-jdk16-146.jar library, then it could be loaded by the application. My solution was to create the keystore with this older library.

Presumably this will also be the case for older API versions; try older versions of BouncyCastle when creating the keystore.
