Зашифрованные сообщения с RSA и PHP

0 голосов
/ 20 марта 2020

Я новичок в разработке в php, и я студент, моя цель - разработать зашифрованный чат с сервером на одной стороне, который шифрует параметры отправки сообщений через сокет, и на стороне клиента, которая дешифрует сообщение значениями.

Я уже выполнил алгоритм шифрования RSA. html, но не могу получить значение сокета на стороне клиента RSAde c. html.

На клиенте со стороны мы отправляем поля n и d и зашифрованное сообщение для серверной части.

И я знаю, как записать их значения на их расшифрованной стороне на стороне клиента, но я не сделал этого в своем коде.

Я сделал клиент только с PHP clientvxx. php В противном случае, в форме чата, это 2-й шаг. Я также нашел способ общаться в JavaScript, он работает, но вы должны получить сообщение, кодирующее и декодирующее его, я не могу этого сделать.

Я использовал: socket_send () для отправки пакета socket_recv I невозможно получить

Примечание: у вас есть право менять языки программирования, например, на JAVA или даже на JAVASCRIPT / PHP;)

Вот мои коды: RSA код части передатчика:
