Thanks @letsencrypt for providing the world with free and easy encryption. Upgrade your Android or install Firefox on it if you want to stay compatible with Let’s Encrypt protected websites after Sept 2021. https://t.co/XSpVZ9Bj0x

May I ask a question? Google created this mess by not having a working update process for Android. Google owns (afair old, widely installed) CA roots. Couldn't Google cross-sign a new LE intermediate? https://t.co/3Sun71MbvZ

On Jan 11 2021, @letsencrypt will switch to the R3 Intermediate and certificates will chain the X1 Root. https://t.co/XlN8NXkcmt

If you use Let's Encrypt SSL certificates for your org, this article is a must read. They are changing their Root Cert, as well as the ACME client API. https://t.co/xmsRIEJgnQ

Ugh: Some websites will stop working on older Android versions on Sep 1, 2021

Currently, 33.8% of Android devices are running v7.0 or lower. After 9/1/21 those devices would receive certificate errors when users visit sites w/a Let’s Encrypt certificate: https://t.co/Phs6M1gGyy pic.twitter.com/dvTS5NDOWy

私もお世話になってる Let's Encryptは2021年9月1日にクロス署名に依存していたDSTルートX3証明書の有効期限が切れるので、過去4年間更新されていないデバイスではX1ルート証明書を信頼出来ない場合があるとのこと。Androidデバイスの3分の1がそうなる可能性があるとのこと。 https://t.co/d8PwST4ZZS

세계 최대 규모의 CA인 렛츠인크립트가 내년부터 자체 루트 인증서만을 사용키로 결정함에 따라(기존까지는 IdenTrust의 루트인증서도 교차서명함) 안드로이드 7.1.1 이전의 구식 기기에서 렛츠인크립트 인증서를 사용하는 사이트들이 열리지 않게된다고. https://t.co/dYWCsoyrQl

— inlets (@inletsdev) November 7, 2020

Let's Encryptは最初IdenTrustからクロスシグニチャを受ける形で立上げたが、今後は自前のroot証明書で自立する。これに伴い、v7.1.1未満のAndroidからLet's Encrypt使用サーバに繋がらなくなる可能性があると。Oculus Goと初代Questは確かAndroid 7.1なので該当するか…？ https://t.co/foebVBkVZt
