How can we do transaction signing in mozilla firefox by loading PKCS#11 library to database. after some research i found about capicom library. but the thing is this library does not support with windows7 and higher versions.
回答1:
you cannot use c code but you can do the same by java applets which are to be signed. Please refer http://www.nakov.com/books/signatures/Java-for-Digitally-Signing-Documents-in-Web-book-Nakov.html

Extension signTextJS does exactly what you need and can be easily modified if needed because its source code is available on GitHub.
