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

For your convenience we also include file checksums:

    * sha1sum  174bc89618a30db2509fd991df7becf0fd17ff9b
    * md5sum   bf5822863b98d25277b362e80b4ef198

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