keychain exporter/ing code?

[René J.V. Bertin]

Hi,

I'm looking for some code that will allow me to export the entire contents of Apple keychains, if possible directly in a way that I can import the data in another cross-platform utility.
I should be able to write something based on the "security" (example?) tool but would of course prefer to use an already tested library.

Any suggestions?

Thanks,
René
