This signature file may be used to cryptographically verify file integrity,
like this::

    $ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xA16EB94D
    $ gpg --list-keys 0xA16EB94D
      pub   2048R/A16EB94D 2008-08-15 [expires: 2023-08-12]
      uid   Turnkey Linux Release Key <release@turnkeylinux.com>

    $ gpg --verify turnkey-nginx-php-fastcgi-12.1-squeeze-i386.iso.sig
      gpg: Signature made Thu Apr 18 13:18:23 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  4f13b6aeef515a327faaaffb2ac6059ec8a1d284
    * md5sum   d96dbd2eb6b3bc2dc17526dea9cb3c63

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