    $ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xA16EB94D
    $ gpg --list-keys 0xA16EB94D
      pub   2048R/A16EB94D 2008-08-15 [expires: 2023-08-12]

For your convenience we also include file checksums:

    * sha1sum  1156c7ac43eb96f3fd3807ce40161721b9ca6278
    * md5sum   99c25c24b891b48217d74f8d80b5aed7

You can calculate these on your end and compare to check for errors, but
cryptographic verification is recommended for security reasons.
