Aegypten development library from gnupg.org
Created attachment 3271 [details] libksba-0.4.4.ebuild I'd place in dev-libs since libgcrypt is there too. Also, there is very little documentation for this, so I'm not really sure what it is used for, but gpgsm needs it, and I'm making an ebuild for that right now.

Just found out libksba is a X.509 support library.
Commited, thanks for the ebuild!
