Hello:
I'm very new to android and java both, so hopefully I'm missing something easy here. All I want to do is create a simple PKCS10 certificate signing request. I have some code that will compile and run on my ubuntu box (java-6-openjdk), but throws a null pointer exception in the android emulator:
KeyPair myKeyPair = KeyPairGenerator.getInstance("RSA").generateKeyPair();
X500Principal subject = new X500Principal("CN=Test V3 Certificate");
PKCS10CertificationRequest csr = new PKCS10CertificationRequest
( "SHA1withRSA",
subject,
myKeyPair.getPublic(),
null,
myKeyPair.getPrivate()
);
byte[] outBytes = csr.getEncoded();
return new String(outBytes);
In the debugger I can see I have apparently constructed a PKCS10CertificationRequest, but I can't do anything with it (like getEncoded() or even toString()) without error. When I call getEncoded() it fails on the android emulator; this is the stack trace:

I've tried this with both the API levels 7 and 8. I know there's a ton of other details I could post about the versions of various components of my system. Like I said, I'm new to this, so right now I'm more looking for a direction to go in than necessarily a final answer.
Thanks very much,
Adam Mackler
