PGP - Eliminating Temp Files?

I've been following the tutorial at: http://cephas.net/blog/2004/04/01/pgp-encryption-using-bouncy-castle/.

Following this example, I have been able to encrypt files in PGP. The problem is, I just want a few strings that I can then pass along -- I don't need an encrypted file. The strings will be passed in a web query.

Is there a way to only encrypt Strings and not have to first write them to a file? Does the file encryption have to happen? (I'm struggling to find anything to make me believe otherwise,but that just doesn't make sense to me).

thanks

I have not looked at the example in detail but just use any of the memory-based alternatives, for example for a Writer you can use a CharArrayWriter or StringWriter instead of a FileWriter. Similiarly for Readers, InputStreams, etc.

Thanks Greg, will do that today and see what I come up with.

The current solution creates 3 files, I think this will eliminate at least two of them.
