According to [this reddit thread](https://www.reddit.com/r/Bitcoin/comments/69czq6/does_anyone_still_use_bitcoin_armory_im_concerned/) and the comment below, the old Armory developers could no longer work on Armory and the project is maintained by a former employee.

https://www.bitcoinarmory.com/ is the website of the old project, is abandoned, but still has higher Google rank.

https://btcarmory.com/ is the website of the new project.

See Andrew Chow's answer for info about the keys.
