1 GnuPG-2 provides several utilities that are used by mail clients,
2 such as Kmail and Balsa, including OpenPGP and S/MIME support.
3 GnuPG-2 has a different architecture than GnuPG-1 (e.g. 1.4.5) in that
4 it splits up functionality into several modules. However, both
5 versions may be installed alongside without any conflict. In fact,
6 the gpg version from GnuPG-1 is able to make use of the gpg-agent as
7 included in GnuPG-2 and allows for seamless passphrase caching. The
8 advantage of GnuPG-1 is its smaller size and the lack of dependency on
9 other modules at run and build time.
