Secured Client-Side script

Question

I have got a particular requirement where some critical algorithms have to be handled in the client-side script and it got to be secured. Using javascript will just expose the algorithm. I am currently evaluating ways to secure the algorithm on the client script. Appreciate any suggestions and alternative approaches.

One option I am thinking about is to download a small applet to the local PC, get the calculations done in it and update the results back. Before deciding on this, I want to know if a client script itself can be made secure coz that would be much easier.

Thanks in advance!

Answer 1

You CANNOT secure anything on a client PC.

Everything you are doing client-side is crackable and spuffable.

That's the PC of the client. It will be doing anything the client has requested it to do.
