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",
new X500Principal(new X500Name()),
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 it fails on the
android emulator, this is the stack trace:
06-22 04:41:06.143: WARN/System.err(337):

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
