Re: PGPPublicKeyRing from PGPSecretKeyRing

Hi!

Thanks for the hint! Unfortunately the PGPKeyRingGenerator does not what
I need, as I already have an existing PGPSecretKeyRing and don't want to
generate a fresh one.

However, the class pointed me to the List-Constructor of
PGPPublicKeyRing, which unfortunately is package-private in BC 1.59. I
assume, that this constructor will be come public in the next release,
as it already is public in the master branch.

I ended up accessing that constructor using reflections for now, which
does the job for me :)

Thank you for your input :)


PS: Do you have any hint about when the next BC version will be released? :)
