    $ gpg --list-keys 0xA16EB94D
      pub   2048R/A16EB94D 2008-08-15 [expires: 2023-08-12]

For your convenience we also include file checksums:

    * sha1sum  f2629574a504bab447d1212a01b242d5ae6dab19
    * md5sum   88c887fb90aa8b85941981ee6afe15a8

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