Where the other one was saying `document-documents-main`. The same applies to the image. With the image there is also that kind of behavior. It says uikitImageUploader, this one is not using the FileUploader, it is using the ImageUploader which is a little different.

-Regarding the hidden if I was to take one of the hidden fields, let's say the Documents Hidden field, you'll see there is some naming conventions that you need to follow. It says main-documents, it doesn't say documents. You'll see when we add the value back to the page, we're able to target it based on these naming conventions.  That's quite important.

 ### Security - Different Encryption Options

-Then for some security, which is a little extra layer. Like the one guy said, that it's not that we can really stop them, we can just make it very hard. There are different encryption options. This medium encryption (local-file-key) is better than the basic. The basic stores the key in the database, which in that case means that if somebody swiped your database, they do have the key. It could happen that they are able to get hold of your database, but not all of your files. Specially those that are behind the public repository. The medium encryption option can generate a file behind the public folder, which therefore is not publicly accessible. That makes it just that little bit more difficult to get a key to open the value. [00:31:19](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h31m19s) The reason is let's say your documents are not available to every group on your system, maybe  some groups can access that document, then this is another layer of security that's already by default built into the field behavior. That is just looking at the fields.

You'll see, let me show you if we go back on 'allcomplete' there is a function. At some point when everything is satisfied it has a setFilekey, and it passes a bunch of variables to it. It is this function that we're going to look at. [00:32:36](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h32m36s) Let's use that setFileJS and search it.

It has an 'allcomplete'. Even if you look at 'allcomplete' which is a place where the server has told you it's done, everything is good. You can do some house cleaning in the browser. That's what we doing. We're checking if it's done, we take away the progressbar, and if it has an error, we pop out the errors and alert. If it's successful, because we decide what this response going to be. So we will decide to give a successful [00:33:43](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h33m43s) value in the array.

It's quite a lot of code, but it's all being added to the Admin View and it can be used for different Admin Views, [00:34:13](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h34m13s) if it's dealing with either images, documents, or media.
