About
This plugin opts to generate fake links (anchors) controlled with JavaScript to open up a modal once clicked to opt users to complete the anti-spam test with <a href="https://github.com/google/recaptcha/" rel="nofollow ugc">Google reCaptcha</a>.
Once a user successfully submits a test, an AJAX callback will then verify the response and parse the download.
`md5` is used to hash the download links and fetch them later once a user submits a test.
You must provide your Google reCaptcha credentials which you can obtain from <a href="https://google.com/recaptcha/admin" rel="nofollow ugc">this page</a>
Once you activate the plugin, you should now navigate to “Settings” > “reCaptcha Downlaods” (or “Options” > “reCaptcha Downlaods” for network activated plugin) and add your Google reCaptcha credentials (public and private keys) which you can obtain from https://www.google.com/recaptcha/admin
The development version of this plugin is hosted on Github, feel free to fork it, contribute and improve it, or start a new issue if you want to report something like an unusual bug.
Here’s the Github repo: https://github.com/elhardoum/recaptcha-protected-downloads
Thank you!
