Difference between grep with and without extended-regex

• by default grep interpret search pattern as basic regular expression i.e. the meta-characters ?, +, |, ( and ) are interpreted as literal, hence need to escape with backslash
• can pass in extended regular expresson option -E (or --extended-regex) which means it doesn't take the meta-characters literally hence do not need to escape with backslash

Про токены, JSON Web Tokens (JWT), аутентификацию и авторизацию. Token-Based Authentication

Основы:

Аутентификация(authentication, от греч. αὐθεντικός [authentikos] – реальный, подлинный; от αὐθέντης [authentes] – автор) - это процесс проверки учётных данных пользователя (логин/пароль). Проверка подлинности пользователя путём сравнения введённого им логина/пароля с данными сохранёнными в базе данных.

Авторизация(authorization — разрешение, уполномочивание) - это проверка прав пользователя на доступ к определенным ресурсам.

Например после аутентификации юзер sasha получает право обращатся и получать от ресурса "super.com/vip" некие данные. Во время обращения юзера sasha к ресурсу vip система авторизации проверит имеет ли право юзер обращатся к этому ресурсу (проще говоря переходить по неким разрешенным ссылкам)

The following attack will display a "you've been signed out" page for GMail, and attempt to steal your account credentials.

DO NOT PUT ANY ACCOUNT CREDENTIALS INTO ANY TABS CREATED AFTER VISITING THESE LINKS :)

I received an email in my GMail inbox with a fake attachment image, styled to look like the real GMail attachment UI:

This linked to a page that ended up displaying a fake "you've been signed out" link, via the data:text/html... URL feature of Chrome:
