## Security

As a basic form of security __Fix::Its__ provides a set of SHA512 checksums for
every Gem release.  These checksums can be found in the `checksum/` directory.
Although these checksums do not prevent malicious users from tampering with a
built Gem they can be used for basic integrity verification purposes.

The checksum of a file can be checked using the `sha512sum` command.  For
example:

    $ sha512sum pkg/fix-its-0.1.0.gem
    26198b7812a5ac118a5f2a1b63927871b3378efb071b37abb7e1ba87c1aac9f3a6b45eeae87d9dc647b194c15171b13f15e46503a9a1440b1233faf924381ff5  pkg/fix-its-0.1.0.gem
