php javascript java апплет смарт-карты подписание pdf на сервере

Вам понадобится что-то, что работает на компьютере пользователя, и это позволяет вырваться из его обычной песочницы, например, подписанного java-апплета. С такой штукой вещи, некоторые javascript + AJAX и обратно и вперед связь с вашим сервером, вы, безусловно, могли бы сделать то, о чем вы говорите.

Возможно, вам придется загрузить файл с компьютера пользователя.

Как написать апплет смарт-карты java

официальный сайт технологии Java Card

Я, будучи бельгийским гражданином, также имею идентификационную карту смарт -карты , которую можно использовать для подписи документов через Интернет или доступа к вещам через апплет

Уэтер это легко, теперь это другой вопрос. 🙂

Я закончил апплет, используя bouncy castle и itext libs.У меня были проблемы с подписью моего апплета и libs.This была решена с помощью Ant в Eclipse. Апплет можно увидеть по адресу http: // www. correatemeonline.com/applet/japplet.html .
