    I WAS PLAYING AROUND WITH THIS SITE: site: [url removed, login to view] and wanted something similar with some serious additions. I wish a user to be able to upload any file and have that file transfered into code. such as hexadecimal, however they will then be able to use a generator to be able to then turn the code back into its original form as they wish. I wish this to be simple and easy, however the user should be able to transfer any kind of file in this format no matter how large, such as videos, mp3, text, word docs, pdf's, images...anything. I would like this project to be delivered as an online project with addition option to download the converter software if possible. for example i transfered a youtube video to hexadecimal and this is the output it gave me: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

    Hello, I need to have bitcoin functionality integrated into my website. This would require wallet functionality for users to deposit bitcoin on the site. From there users can use the amount they deposited on website activities and then to be able to withdraw the currency afterwards if they still have a balance remaining. Possible platforms to complete the project would be the use of the Bitcoin BlockChain and BitGo API. Thank you
