You tagged this question "C++"; I have corrected it for you.

Not clear. And there is not such thing as "java script" (Java is not a scripting language ;-)

I believe you are having a fundamental issue understanding what happens on what code is executed on the server and what code is executed on the client.
If you are attempting to encrypt something using javascript and you want to use server side code to achieve this, you are going to be sending the raw, unencrypted data over the internet back to your site to initiate the encryption. The way you would do this is using an ajax call to a WebMethod on your server which acts as a wrapper to the business layer object.
I would highly suggest that you DO NOT DO IT LIKE THIS! If you have sensitive information being passed from the page to the server then your better solution would be to implement SSL for that portion of the site.

Hi,

You can do one thing please call that business layer method before your javascript function call and put that in hiddenfield and after that use hiddenfield's value as the parameter value.

Thanks!
