Bouncy Castle: PGPKeyRingGenerator

[Alan Melrose]

Hi,
I'm triying to create a software tha generate pgp keys for blackberry. I am using Bouncy castle pgp library. I had no problem creating pgp key pairs but i can't figure out how to create PGP key rings and this is what i need because pgp for blackberry requires subkeys. Here is my code:

public PGPSecretKeyRing createKey(String email,char[] password) {
		KeyPair keyPair = null;
		PGPKeyPair secretKey=null;
		PGPSecretKeyRing skr=null;
		try {
			
			KeyPairGenerator  keyPairGen = KeyPairGenerator.getInstance("RSA", "BC");
			keyPairGen.initialize(4096);

			keyPair = keyPairGen.generateKeyPair();
			
			PGPSignatureSubpacketGenerator hashedGen = new PGPSignatureSubpacketGenerator();
			

			hashedGen.setKeyFlags(true, KeyFlags.CERTIFY_OTHER | KeyFlags.SIGN_DATA
			                             | KeyFlags.ENCRYPT_COMMS | KeyFlags.ENCRYPT_STORAGE);


			hashedGen.setPreferredCompressionAlgorithms(false,
					new int[] {CompressionAlgorithmTags.ZIP});

			hashedGen.setPreferredHashAlgorithms(false,
					new int[] {HashAlgorithmTags.SHA1} );

			hashedGen.setPreferredSymmetricAlgorithms(false,
					new int[] { SymmetricKeyAlgorithmTags.AES_256});

			secretKey = new PGPKeyPair(
					PGPSignature.POSITIVE_CERTIFICATION, 	
					keyPair.getPublic(), 		
					keyPair.getPrivate(), 	
					new Date());				

			PGPKeyRingGenerator    keyRingGen = new
			PGPKeyRingGenerator(PGPSignature.POSITIVE_CERTIFICATION, secretKey,
					email+"<"+email+"@"+gui.getDomain()+">", PGPEncryptedData.AES_256, password,true, 
					hashedGen.generate(), null, new SecureRandom(), "BC"); 


			 skr=keyRingGen.generateSecretKeyRing();
			 

		} catch (Exception e) {

			e.printStackTrace();
		}
		

		return skr;
	}

Here are the errors I get:

If anyone ever used Bouncy castle and knoe hoe to generate pgp key rings any help would be appreciated!
Thanks

Ok found my problem here's the solution:

secretKey = new PGPKeyPair(
					PGPPublicKey.RSA_GENERAL, 	
					keyPair,	
					new Date());	
			PGPKeyPair secretKey2 = new PGPKeyPair(
					PGPPublicKey.RSA_GENERAL, 	
					keyPair2,	
					new Date());		

			PGPKeyRingGenerator    keyRingGen = new
			PGPKeyRingGenerator(PGPSignature.POSITIVE_CERTIFICATION, secretKey,
					email+"<"+email+"@"+gui.getDomain()+">", PGPEncryptedData.AES_256, password,true, 
					hashedGen.generate(), null, new SecureRandom(), "BC"); 

			keyRingGen.addSubKey(secretKey2);
			 skr=keyRingGen.generateSecretKeyRing();

Hi,
I am also working on PGP keypair generation in blackberry and I am totally new to this.Can you please guide me how to do that?
