Let’s Encrypt предложила вариант продления срока службы своих сертификатов в старых версиях Android

В Let’s Encrypt рассказали, как избежать проблемы истекающего корневого сертификата на устройствах со старыми версиями Android. В 2021 году завершается срок соглашения Let’s Encrypt с IdenTrust, поэтому браузеры и ОС без корневого сертификата Let’s Encrypt больше не будут работать с сайтами и службами, которые используют этот сертификат. Проблема коснется устройств с версиями Android до 7.1.1 Nougat.

Согласно официальной статистике Google, 33,8% активных пользователей Android используют более ранние версии. Это примерно 845 млн человек.

Теперь Let’s Encrypt объявил, что нашел решение, которое позволит старым смартфонам Android работать, продолжая использовать просроченный сертификат от IdenTrust. В центре сертификации пояснили, что IdenTrust согласился выпустить трехлетнюю перекрестную подпись для Let’s Encrypt ISRG X1 и их собственного корневого центра сертификации DST X3. Решение будет работать благодаря тому, что в Android не обеспечивается соблюдение сроков истечения действия сертификатов доверия. ISRG и IdenTrust уже обратились к аудиторам, чтобы убедиться в отсутствии проблем.

Срок действия самоподписанного сертификата, который представляет собой пару ключей DST Root CA X3, истекает. Но корневые хранилища браузера и ОС не содержат сертификатов как таковых, а включают якоря доверия и стандарты для проверки. Android намеренно решил не использовать поле notAfter для якорей доверия. ISRG Root X1 не был добавлен в старые доверенные хранилища Android, а DST Root CA X3 не был удален. То есть, он может без проблем выдать перекрестную подпись, срок действия которой превышает срок действия его собственного самоподписанного сертификата.

Let’s Encrypt начнет предоставлять сертификаты ISRG Root X1 и DST Root CA X3, которые обеспечат «бесперебойное обслуживание всех пользователей и предотвратят потенциальные сбои».

Таки образом, ранее запланированная отмена режима перекрестной подписи начнется 11 января 2021 года. Одновременно пользователям предоставят новую цепочку по умолчанию. Срок действия новой перекрестной подписи истекает в начале 2024 года.

Ранее пользователям предлагали другой вариант решения проблемы. Они могли установить Firefox, который использует собственное хранилище сертификатов. Однако этот шаг решал проблему браузеров, но не клиентов или функций.

Обновление пользовательской версии Android также доступно не всем, так как производители прекращают поддержку смартфонов, как правило, через три года после выпуска.

Install SSL Certificate on Android

Android, developed by Google and active since 2007, is the world’s most used Mobile operating system—it has been adopted by millions of mobile users. Its simplified & an eye-catching User interface (UI), End-to-End encryption and security, robust architecture, Open-source platforms, and other useful features are the reason that it has attracted so many device manufacturers and End-Users.

Android offers the following security to its users:

  • Android Application Sandbox to isolate app data and code execution from other applications.
  • An SSL certificate or HTTPS certificate protects the application code and App-server communication in public Wi-Fi zones and private VPN.
  • To eliminate Memory Management Errors, it uses ASLR, NX, ProPolice, safe_iop, OpenBSD dlmalloc, OpenBSD calloc, and Linux mmap_min_addr technologies.
  • It helps to encrypt the function of file system management, which is usually inbuilt in phone system by vendors to decrease the changes of data loss.
  • To restrict the access of some features and data it offers User-granted permissions and settings.
  • It offers application-defined permissions for controlling the application data for individual Apps.
  • Robust Security functions such as cryptography, permissions, and secure

Let’s talk about Android security with an SSL Certificate.

An SSL Certificate (aka TLS – Transport Layer Security) is a bridge between clients (Android App) and servers, which secures ongoing communication. So, when an Android user accesses an SSL certificate enabled application, SSL ensures the information shared will not be intercepted or accessible by any other person or robot.

While doing online transactions, accessing social media accounts, email accounts, social apps, accessing images and videos, synchronizing one app with another app/function, accessing banking apps, playing online games, etc. Security is needed most because Cyber Criminals may target applications directly or by injecting malware/threats into users’ devices. Lack of security in an android device can cause a user to become the victim of cyber-attacks. Public Wi-Fi ports can be even riskier, and are one of attackers’ favorite spots to dig into users’ systems.

SSL certificate offers a secured environment, which is vital to an Android user, whether the user is operating apps over Wi-Fi or using VPN, SSL will always protect the information.

How to Secure an Android App with an SSL Certificate?

First of all, get an SSL certificate from a trusted SSL Certificate Authority such as Comodo, Symantec, RapidSSL, GeoTrust or Thawte. Complete the SSL purchase and validation process as per the Certificate Authority’s instructions.
