Bouncy Castle API: invalid header encountered - using GnuPG v1.4.9 (MingW32) key

[Rakesh Megharaj]

Actually the application which was using GNUPG tool, I am replacing it to use Bouncy Castle (with bcprov-jdk15on-147.jar in the lib folder).I tried to encrypt a file in Bouncy castle api using a public key GnuPG (tried using .gpg as well as .asc file). I am using the bouncy-castle API, I am getting the below error mesage, please advise what direction I should take?

The key I have is using GnuPG v1.4.9 (MingW32) key


java.io.IOException: invalid header encountered

So what code are you using to encrypt? You do mean encrypt and not decrypt don't you?

I've resolved the issue, needed to convert java.IO.InputStream to a BCPGInputStream using PGPUtil.getDecoderStream before creating PGPPublicKeyRingCollection.
Thanks
