How to encrypt pdf files and display them in web in a way that the data is encrypted in the inspect element and no one can see the direct link so that cannot be downloaded.
Is there any web service or software to do this?
Do you mean you want prevent them from save?

A client has asked that I include a "View in browser" link to a pdf attached to an email. This should open the same PDF in the user's default web browser. I have a PDF editor (PDFescape Desktop) that I can successfully use to add links to webpages, and it seems capable of opening files, and even executing javascript, though I've never tried it (I am proficient in JS though so that's an option if anyone has any ideas).
The only thing I can think of is to host the PDF somewhere and then link to it's location, but I'd rather not use a third party server if I can help it.
Is there any way to reference a link in a PDF to the same PDF the link exists in?
I am working on React-Native mobile app and I need to handle pdf file coming from the server. The idea is when the user clicks on button, a request to the server is made and a pdf file is returned. My question is how to download and parse this file and show it to the user?
You can do it in app BUT you are going to have a lot of pain, especially with android devices.
My advice is using the Linking api and open a webbrowser:
https://facebook.github.io/react-native/docs/linking
The idea is to check if your url contains a .pdf. You can use a mix of:
https://lodash.com/docs/#includes
https://lodash.com/docs/#filter
https://lodash.com/docs/#split
When you are sure that your url is a pdf, you can use:
Linking.openURL(url);
I am trying to download (backup) images that customers upload for products that take custom logos (these are typically JPG, PNG, PDF, etc.) These customer files are downloadable by clicking on a hyperlink in the BigCommerce admin page for the order in question. The link is not a link to the image path but instead, a link to a service that sends the file to the browser. In other words, you have to be authenticated into the admin site to download the file. The URL looks like this:
https://mystore.com/internalapi/v1/orders/383945/products/251438/attributes/561518/download
https://mystore.com/internalapi/v1/orders/{order id}/products/{lineItem id}/attributes/{option id}/download
These are easily constructed in the API itself for a given order. If I use the link in a browser tab while I'm logged into the admin site, the file downloads.
But what I am trying to write an app to automatically download all the files (there are thousands). When I try to use this URL in an app, I get a authentication error. I tried at first using my regular API credentials but then used the credentials to log into the admin site. Both give me an authentication error.
I could not find anything documented on this so-called "internalapi." Anyone ever try to use this "internal" API that is used by the admin site?
I believe authentication is cookie based for that internal API, but there could be problems with using our non-publicly documented internal APIs in production, i.e. we may make future updates that would be breaking changes.
Images attached to orders through a file upload option also get copied to WebDAV, in the dav/product_images/configured_products folder. Another way to do this could be to use a WebDAV client library like easywebdav to connect and download the files.
I am exporting crytsal report to pdf format and saving the pdf on azure cloud. This code is written in web api. I am also able to download the pdf on client. Is there any way with which I can open this saved pdf file on client side by either using server side code or using jQuery. I just want to keep the file open for the user to view.
Maybe you can have a link point to the PDF file address with response header "response-content-disposition": "inline; filename=this.pdf", "response-content-type": "application/pdf". Then I think the browser will launch proper PDF plugin to show it.
I have posted some other smaller questions regarding the problem I describe below and got some feedback but now I will try to explain it in more depth hoping to get through the problem.
I built a desktop application using JavaFX 2.2 which uses a WebEngine to access a website built using Oracle ADF Pages. The application tracks the users actions on the pages and stores data to a database. All fine so far until the point where I need show a PDF file on a user click.
On the actual website the user clicks a button and a new popup window opens up that displays the PDF.
My problem is that due to the lack of PDF support in JavaFX I cannot display the pdf. The actual link to the PDF is dynamic and it doesn't have a .pdf at the end of it so I can't use the actual URL to send it to an external bowser or something to display it. Additionally the connection is secure so I can't open the URL with Chrome for example.
Possible solutions I thought about are to read the binary data of the response from WebView and create the PDF file locally and then open it using Adobe of Chrome or something. Is that possible at all?
Another solution I thought about (while I am writing this question) is maybe to open the URL which the users default browser but how can I go about sending the secure connection cookie from the application to the browser.
Is any of the above even possible? Am I missing something?
Any help, clues, links, ideas would be very much appreciated.
Thanks
I think the best way to do what you want is to download the PDF and display it locally.
Downloading using WebView sounds like it could work but I'm not familiar with the user experience. As an alternative try using curl or wget. You can pass in the authorization cookie to those tools and use them to download the file
