To jumpstart its trust relationship with various software and browser makers \u2013 necessary for its digital certificates to be accepted \u2013 it piggybacked on IndenTrust&#8217;s DST Root X3 certificate. As a result, the non-profit&#8217;s certificates could be presented by websites and be trusted by all the major web browsers to connect to them securely.<\/p>\n<p>The CA, overseen by the Internet Security Research Group (ISRG), subsequently issued its own root certificate (ISRG Root X1) and applied for it to be trusted with the major software platforms. By July, 2018, the ISRG Root X1 had been accepted by Microsoft, Google, Apple, Mozilla, Oracle, and Blackberry, and it was no longer really necessary to have IndenTrust&#8217;s DST Root X3 vouch for Let&#8217;s Encrypt&#8217;s character.<\/p>\n<p>Next year, on September 1, 2021, the DST Root X3 certificate that Let&#8217;s Encrypt initially relied for <a target=\"_blank\" rel=\"nofollow noopener noreferrer\" href=\"https:\/\/letsencrypt.org\/2015\/10\/19\/lets-encrypt-is-trusted.html\">cross-signing<\/a> will expire and devices that haven&#8217;t been updated in the past four years to trust the X1 root certificate may find they&#8217;re unable to connect to websites securely, not without throwing up error messages, at least. We&#8217;re looking at you, Android.<\/p>\n<p>&#8220;Some software that hasn\u2019t been updated since 2016 (approximately when our root was accepted to many root programs) still doesn\u2019t trust our root certificate, ISRG Root X1,&#8221; explained Jacob Hoffman-Andrews, a lead developer on Let&#8217;s Encrypt and senior staff technologist at the Electronic Frontier Foundation, in a <a target=\"_blank\" rel=\"nofollow noopener noreferrer\" href=\"https:\/\/letsencrypt.org\/2020\/11\/06\/own-two-feet.html\">notice<\/a> on Friday.<\/p>\n<p>&#8220;Most notably, this includes versions of Android prior to 7.1.1. That means those older versions of Android will no longer trust certificates issued by Let\u2019s Encrypt.&#8221;<\/p>\n<p>The trust lapse will hit about a third of the Android devices currently operating, Hoffman-Andrews claims. With more than 2.5bn active Android users, the impact will be noticeable, though not too much so \u2013 those aging Android devices account for only about one to five per cent of internet traffic, apparently. Still, it&#8217;s worth mentioning.<\/p>\n<div class=\"promo_article\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/regmedia.co.uk\/2019\/11\/20\/shutterstock_us_police.jpg?x=174&amp;y=115&amp;crop=1\" width=\"174\" height=\"115\" alt=\"Police officers in the US\"><\/p>\n<h2 title=\"Massive public records request reveals scale of warrantless surveillance\">Thought the FBI were the only ones able to unlock encrypted phones?

And that remains the case today.<\/p>\n<p>Unfortunately, Hoffman-Andrews says that there&#8217;s not much that can be done to ensure Android hardware partners update their devices. And, he adds, buying everyone a new phone isn&#8217;t a realistic option.<\/p>\n<p>One meaningful thing that affected Android users can do is use Firefox, which comes with its own list of trusted root certificates and thus should recognize the ISRG Root X1 certificate.<\/p>\n<p>Hoffman-Andrews says that starting January 11, 2021, Let&#8217;s Encrypt will implement a change in its API to allow Automatic Certificate Management Environment (ACME) <a target=\"_blank\" rel=\"nofollow noopener noreferrer\" href=\"https:\/\/letsencrypt.org\/docs\/client-options\/\">clients<\/a> like Certbot to serve a certificate chain pointing to the ISRG Root X1 by default. But the plan is to maintain an option to set up an alternate link relation tied to the older DST Root X3 certificate for the sake of compatibility.<\/p>\n<p>Those who get Let&#8217;s Encrypt certs from their hosting provider are advised to get in touch with the provider if there are issues with the root certificate being presented. \u00ae<\/p>\n<p> READ MORE <a
