In this howto we'll install the pepperflashplugin-nonfree package from the contrib section of Wheezy backports. When both are installed on one system, then Chromium currrently only sees the Pepper Flash Player. Pepper Flash Player uses a different interface with the browser than Adobe Flash Player, so it doesn't fit in the mechanism of 'alternatives' (flash-mozilla.so).

Both packages will co-exist for some time, until Adobe finally ends security support for the Adobe Flash Player. Users can choose between Adobe Flash Player and Pepper Flash Player by installing the corresponding Debian package. The package is a separate Debian package, not integrated in flashplugin-nonfree. Pepper Flash Player can currently only be used with Chromium (and with Chrome). Google provides newer features in Pepper Flash Player. Adobe currently still provides security fixes for Adobe Flash Player.

Pepper Flash Player is maintained by Google, and is newer than Adobe Flash Player. Though much content can be viewed with html5, still many pages require flash to work.
