Paid on delivery
Functionality is needed for an existing ASP.NET web forms application to upload/download files that are encrypted/decrypted in the browser with JavaScript prior to uploading to the server. A form should be built that includes a file upload component that allows multiple files, unlimited file size, and has a progress bar. The component should use AES and accept a password which is used to create the key (must use a strong PBKDF). Other details regarding cryptography and security details will be discussed later. The selected Freelancer must have strong JavaScript skills as well as security knowledge (e.g. cryptographic standards).

Hi there I can build you something which send data from client side in a encrypted way to the server side. We can use AES as we already have done it before. And for good security we can make the AES private key dynamic by using session or view bag. So please ping me for more details.

I have worked with uploading and downloading files(unlimited size) from server on c#. It should not take much time. I need the exact requirements for progress bar. So for the safest side, I have given my estimate as 7 days. If the progress bar needs to show the progress of uploading a file, then it's doable within 5 days.
