+This is the Security Policy for the Perl distribution Crypt-URandom.
+
+The latest version of this Security Policy can be found in the git repository at
+[https://github.com/robrwo/Crypt-URandom](https://github.com/robrwo/Crypt-URandom).
+
+This text is based on the CPAN Security Group's Guidelines for Adding
+a Security Policy to Perl Distributions (version 0.1.9).
+https://security.metacpan.org/docs/guides/security-policy-for-authors.html
+
+# How to Report a Security Vulnerability
+
+Security vulnerabilties can be reported by e-mail to the current
+project maintainer(s) at <ddick@cpan.org>.
+
+Please include as many details as possible, including code samples
+or test cases, so that we can reproduce the issue.
+
+If you would like any help with triaging the issue, or if the issue
+is being actively exploited, please copy the report to the CPAN
+Security Group (CPANSec) at <cpan-security@security.metacpan.org>.
+
+Please *do not* use the public issue reporting system on RT or
+GitHub issues for reporting security vulnerabilities.
+
+Please do not disclose the security vulnerability in public forums
+until past any proposed date for public disclosure, or it has been
+made public by the maintainers or CPANSec.  That includes patches or
+pull requests.
+
+For more information, see
+[Report a Security Issue](https://security.metacpan.org/docs/report.html)
+on the CPANSec website.
+
+## Response to Reports
+
+The maintainer(s) aim to acknowledge your security report as soon as
+possible.  However, this project is maintained by a single person in
+their spare time, and they cannot guarantee a rapid response.  If you
+have not received a response from the them within a week, then
+please send a reminder to them and copy the report to CPANSec at
+<cpan-security@security.metacpan.org>.
+
+Please note that the initial response to your report will be an
+acknowledgement, with a possible query for more information.  It
+will not necessarily include any fixes for the issue.
+
+The project maintainer(s) may forward this issue to the security
+contacts for other projects where we believe it is relevant.  This
+may include embedded libraries, system libraries, prerequisite
+modules or downstream software that uses this software.
+
+They may also forward this issue to CPANSec.
+
+# What Software this Policy Applies to
+
+Any security vulnerabilities in Crypt-URandom are covered
+by this policy.
+
+Security vulnerabilities are considered anything that allows users
+to execute unauthorised code, access unauthorised resources, or to
+have an adverse impact on accessibility or performance of a system.
+
+Security vulnerabilities in upstream software (embedded libraries,
+prerequisite modules or system libraries, or in Perl), are not covered
+by this policy unless they affect Crypt-URandom, or
+Crypt-URandom can be used to exploit vulnerabilities in
+them.
+
+Security vulnerabilities in downstream software (any software that
+uses Crypt-URandom, or plugins to it that are not included
+with the Crypt-URandom distribution) are not covered by
+this policy.
+
+## Which Versions of this Software are Supported?
+
+The maintainer(s) will only commit to releasing security fixes for the
+latest version of Crypt-URandom.
+
+Note that the Crypt-URandom project only supports major
+versions of Perl released in the past ten (10) years, even though
+Crypt-URandom will run on older versions of Perl.  If a
+security fix requires us to increase the minimum version of Perl that
+is supported, then we may do that.
+
+# Installation and Usage Issues
+
+Please see the module documentation for more information.
