VKEncrypt Extension

Данное расширение предназначено для шифрования личных сообщений социальной сети «ВКонтакте».

- Легко использовать;
- Не сохраняются данные между сессиями для обеспечения защиты;
- Обеспечивается защита от различных криптографических атак (атака повторного воспроизведения, аналитические атаки);
- Имеется возможность генерации ключа для одноразовой переписки;
- Используется алгоритм шифрования AES-256;
- Частичная поддержка мобильной версии (m.vk.com)

ПОЛИТИКА КОНФИДЕНЦИАЛЬНОСТИ
VKEncrypt использует разрешение для редактирования содержимого страницы сайта vk.com/vk.ru. Данное разрешение необходимо для отображения элементов управления расширения и замены шифротекста сообщений на расшифрованный текст.
Никакие данные пользователя не используются дополнением для сбора информации, статистики или с любой другой целью.
Никакие данные пользователя не сохраняются дополнением в хранилище браузера, файл или другое хранилище информации.

VKEncrypt использует следующую информацию для своей работы:
1. Уникальный идентификатор пользователя - Адрес страницы (Profile link), установленный вручную пользователем или же оставленный по умолчанию самой социальной сетью (вида idXXXXXXXXX). Идентификатор пользователя используется исключительно в процессе генерации криптографического ключа. Изменение уникального идентификатора пользователя приведет к невозможности расшифровать ранее отправленные сообщения.
2. Локальное время компьютера/мобильного устройства - число миллисекунд, прошедшее с 1 января 1970 года до момента отправки сообщения. Значение времени отправки сообщения используется как в процессе генерации криптографического ключа, так и при составлении заголовка сообщения, который отправляется в незашифрованном виде. Изменение локального времени может привести к ошибочной работе системы обнаружения атаки повторного воспроизведения (replay attack).

Перечисленная выше информация используется исключительно для работы систем дополнения.

PRIVACY POLICY
VKEncrypt uses permission for changing the content of the website vk.com/vk.ru. This permission is required for displaying controls and changing the content of the encrypted messages to decrypted text.
No personal data is used by this add-on for information gathering, statistics or with any other purpose.
No personal data will be stored by this add-on in browser storage, local file or any other kind of information storage.

VKEncrypt uses the following data for its work:
1. Unique user identifier - Profile link set by user or by the social network as default one (like idXXXXXXXXX). User identifier is used for cryptographic key generation only. Any changes of user unique identifier will cause inability to decrypt any previous messages.
2. Local time of computer/mobile device - amount of milliseconds from 1 January 1970 to the message sending. This value is used both in the cryptographic key generation process and as a part of encrypted message header which will be unencrypted. Any changes to local time can cause inconsistent behaviour of the system of replay attack detection.

This information is used only for the extension functioning.
