Protect Download Links | Secure Download Link Expiry

Easy to install on almost any server supporting PHP. No PHP knowledge is needed.

No database or cookies needed

Adding Linklok URL to a page is a breeze. A line is added to the top of the page which enables Linklok and then each link you want to secure is just a simply function call added to your existing links.

Securely hides the true location of files on your server. Links do not contain the location of the files on your server, not even in encrypted form.

Your download files can be stored on your server, Amazon S3, Dropbox, Backblaze B2 Cloud Storage, Digital Ocean Spaces or Google Cloud Storage.

New Feature

Files can be stored outside of your webroot if supported by your server.

Download links generated by Linklok can have an expiry time set which can be from minutes up to several years. They can also be set to never expire in which case they simply hide the location of the file on your server.

As well as the expiry time set in the links Linklok can also IP lock them to the user.

Can work with a form of your own design to can collect user data and email out one or more download links. These links can be time and IP locked if required. The form data submitted is forwarded to you by email together with the users IP and optionally the IP country. Form data can also be logged in a text file if required. Using this method only users who enter a real valid email address will get your links.

Forms can use the built in CAPTCHA code field to stop spam

Can optionally block free or other types of email addresses from receiving the download links. This helps to ensure that you get valid emails where clients can really be contacted.

Can stop bandwidth theft (anti leeching)

Links can point to an html or PHP page on your server instead of a download. However please note that the security only applies to the page pointed to and not onward links from that page.
