Java Security

Hi,

I need to do encryption using a GPG Public Key.

This i understand cannot be used in Java Key Store which accepts only X.509 Certificates.

I see from some docs which states Bouncy Castle support s GPG encryption.

I am unable to get the exampel to work.

This is what i want to do:

Given a string, encrypt using a GPG public key.

I would want to do the decryption too using it's corresponding private key.

This is what i see when i run the ByteArrayHandler (BouncyCastle Sample - open

"The provider BC may not be signed by a trusted party"
Starting PGP test
Exception in thread "main" org.bouncycastle.openpgp.PGPException: Exception creating cipher
at org.bouncycastle.openpgp.PGPEncryptedDataGenerator.open(PGPEncryptedDataGenerator.java:451)
at org.bouncycastle.openpgp.PGPEncryptedDataGenerator.open(PGPEncryptedDataGenerator.java:475)
at org.bouncycastle.openpgp.examples.ByteArrayHandler.encrypt(ByteArrayHandler.java:170)
at org.bouncycastle.openpgp.examples.ByteArrayHandler.main(ByteArrayHandler.java:190)


Some of the other samples like , SingedFileProcessor works and generates the key files.

Appreciate if somebody could assist me in getting this to work or any other sample that allows me to work with GPG.

Thanks,
