Thus the certificates used in Istio do not have service name, which is the information that curl needs to verify server identity. As a result, we use curl option ‘-k’ to prevent the curl client from verifying service identity in server’s (i.e., productpage) certificate. Please check secure naming <a href="/v0.3/docs/concepts/security/mutual-tls.html#workflow">here</a> for more information about how the client verifies the server’s identity in Istio.</p><h2 id="further-reading">Further reading</h2><ul><li>Learn more about the design principles behind Istio’s automatic mTLS authentication between all services in this <a href="/v0.3/blog/istio-auth-for-microservices.html">blog</a>.</li></ul></div></div></div></div></div></div><script src="/v0.3/js/sidemenu.min.js"></script><footer><div class="container"><div class="row"><div class="col-lg-2 col-md-2 col-sm-2"></div><div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 center-block"><ul><li><a class="header" href="/v0.3/docs/welcome">Docs</a></li><li><a href="/v0.3/docs/concepts">Concepts</a></li><li><a href="/v0.3/docs/setup">Setup</a></li><li><a href="/v0.3/docs/tasks">Tasks</a></li><li><a href="/v0.3/docs/guides">Guides</a></li><li><a href="/v0.3/docs/reference">Reference</a></li></ul></div><div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 center-block"><ul><li><a class="header" href="/v0.3/help">Help</a></li><li><a href="/v0.3/faq">FAQ</a></li><li><a href="/v0.3/glossary">Glossary</a></li><li><a href="/v0.3/troubleshooting">Troubleshooting</a></li><li><a href="/v0.3/bugs">Report Bugs</a></li><li><a href="https://github.com/istio/istio.github.io/issues/new?title=Issue with _docs/tasks/security/mutual-tls.md">Doc Bugs & Gaps</a></li><li><a href="https://github.com/istio/istio.github.io/edit/master/_docs/tasks/security/mutual-tls.md">Edit This Page</a></li></ul></div><div class="col-lg-3 col-md-3 col-sm-3 col-xs-12 center-block"><ul><li> <a class="header" href="/v0.3/community">Community</a></li><li> <a href="https://groups.google.com/forum/#!forum/istio-users" target="_blank" rel="noopener">User</a> | <a href="https://groups.google.com/forum/#!forum/istio-dev" target="_blank" rel="noopener">Dev Mailing Lists</a></li><li><a href="https://twitter.com/IstioMesh" target="_blank" rel="noopener">Twitter</a></li><li><a href="https://stackoverflow.com/questions/tagged/istio" target="_blank" rel="noopener">Stack Overflow</a></li><li><a href="https://github.com/istio/community" target="_blank" rel="noopener">GitHub</a></li><li><a href="https://github.com/istio/community/blob/master/WORKING-GROUPS.md" target="_blank" rel="noopener">Working Groups</a></li></ul></div><div class="col-lg-1 col-md-1 col-sm-1"></div></div><div class="row"><p class="description small text-center"> Istio 0.3, Copyright © 2017 Istio Authors<br> Archived on 08-Dec-2017</p></div></div></footer><script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.15.0/jquery.validate.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.form/4.2.1/jquery.form.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-visible/1.2.0/jquery.visible.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/slick-carousel/1.6.0/slick.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/1.7.1/clipboard.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script src="/v0.3/js/common.min.js"></script> <script src="/v0.3/js/search.js"></script> <script src="/v0.3/js/prism.min.js"></script></body></html>
