Начал я тут как-то смотреть всякие научные методички по некоторым функциям в программировании. Почему-то подумал, что нужно освежить знания. Так вот, я начал вспоминать все с азов и просто не мог найти нормальный, человеческий материал, который можно просто спокойно прочесть и понять, что прочитал. В конечном итоге, в голову пришла идея, объяснять сложные вещи простыми словами. И так, я начинаю #курс по изучению самых сложных систем, которыми мы пользуемся ежедневно. Сегодня поговори о том, что такое суть слоя защищенных сокетов (SSL).
Вы когда-нибудь замечали замочек в виде значка, который находится в правом углу www-ссылки, на которой вы находитесь? Например, когда вы сидите в онлайн банке или социальной сети. Ну или на худой конец, сайты поисковых систем. Бывает, когда вы этот замочек не замечаете. Например, общаясь в известных мессенджерах или используя какой-то специальную программу, в которой храните определенные данные, которые должны передаваться. В общем, так или иначе, этот замочек имеет название #SSL.
Так что такое SSL?
SSL переводится как Secure Sockets Layer — слой защищённых сокетов. Простыми словами, эта штука обеспечивает более безопасную связь, путем специальных протоколов. Когда вы находитесь на таком соединении, всю информацию, которую вы передаете на сайте, в банке, в приложении или где-либо ещё, надежно шифруется. SSL обладает специальными ключами 2х типов: Общий секретный #ключ и пара открытый/приватный ключ. Открытый ключ используют, чтобы зашифровать данные, а приватный, чтобы их расшифровать. Общий в свою очередь и шифрует, и расшифровывает данные.
#HTTPS (Безопасный протокол передачи гипертекста) обладает безопасностью непосредственно с помощью SSL. Именно поэтому, когда Вы вводите данные своих банковских карт, их видят только Вы и сам протокол, когда вы их передаете. Ведь во время передачи ваших данных находясь, например на сайте, все что бы Вы не сделали, будет зашифровано.
Замечали ли Вы надпись “Небезопасное соединение” или типа-того, когда заходите на сайт? Вот это как раз таки из-за того, что сайт не обладает той заветной S в протоколе HTTPs:// . Это как быть в презервативе. Безопасный #секс намного лучше, чем какой-либо Я постарался вкратце описать суть .
