Https certificates The https protocol uses what are called security certificates, or just certificates, as a kind of positive identification for a website. The process includes documenting your identity as well as proving you have the skills to drive. A certificate for an https website has three similar components: Process: A certificate must be obtained from an issuing authority.

    The process includes proving you own the website for which the certificate will be issued. ID: A certificate is used to prove that the website is the website it claims to be.

    Functionality: A certificate is used to encrypt the data visitors send to and receive from the site. A security certificate is a blob of encrypted data issued after you pay a fee, 1 provide documentation, and pass an identity verification test. Click for larger image. Hint: you start by clicking on Advanced. Possibilities There is something wrong with the security certificate. That means either: The site may not be the site we think it is, and we could be about to hand over sensitive information to an imposter.

    The site may not be able to handle encryption properly, meaning that the connection could be viewed by someone snooping in on the connection. Or, it could mean nothing but an administrative oversight. The trick is knowing which is which. This is perhaps the most common certificate error we see on a regular basis. And yet I see it all the time. There are solutions, of course. The wrong domain In the askleomedia. Yes, it could be a misconfiguration. There are a variety of ways that can happen.

    However, whenever the server responds with the wrong domain name for a secure connection, you need to pay attention. Not cool. Self-signed certificates Official certificates must be purchased. Usually harmless Most of the time, https connection problems are oversights and omissions on the part of the server administrator. As I mentioned, the most common is that the administrator of the server failed to update their certificate. You might contact them and let them know. The problem, of course, is knowing whether or not this is a simple oversight or a malicious interception.

    The whole point of security certificates is to detect those errors because they may indicate various forms of server compromise, or even a compromise of your own computer or internet connection. When in doubt, take the safe route. You should not continue. Do this Subscribe to Confident Computing! Less frustration and more confidence, solutions, answers, and tips in your inbox every week.

    Terms of use What is an expiring link and how to use it I get a lot of questions about what an expiring link on Amazon Web Services AWS actually does and how to use it properly, therefore I thought it useful to explain it in this article. What is an expiring link? An expiring link, also called signed URL, is a link to a file or object that is limited in time. Once it expires, the link is no longer valid.

    This has to advantage that the link cannot be used on another site since it expires in any given time by the rightful owner of the link. Amazon Web Services has a mechanism to generate these links for downloadable files, videos and audios.

    So far, this is easy to understand. But what is not clear for many people is what happens when the link is expired. Does it stay that way? But first of all, how do you generate such a link? You can generate an expiring link via a script you write yourself, but generally it is much easier to use a plugin or extension that does the job for you.

    After all, writing a script means that you need to have a good understanding how AWS works. There are loads of plugins and extensions for WordPress and Joomla available to generate download links. Without that string, the file cannot be downloaded since it is a private file. All files on AWS are per default private unless you change the permission settings not a good idea. When you use a plugin for WordPress or an extension for Joomla, it will create such an expiring link as soon as the visitor lands on the page that contains the shortcode to generate the link.

    This happens on the fly. For example, you could have a link to a PDF residing in a S3 bucket or a download distribution and a plugin that generates the expiring link to that PDF in your post or article. What happens when someone lands on your page? The visitor lands on your page. The expiring link is automatically generated. In other words: As long as the visitor remains on the page, there is a link that is only available for 10 minutes and those minutes start to count the moment the page is loaded.

    But when the visitor comes back another day or reloads the page after the link has expired, a new expiring link is created. The old one no longer exists. This is where the confusion often arises. Many people think that if they set the link to a month, the downloadable file is only available for a month, period. As said, each time that page is loaded, a new link is generated, again for the same amount of time.

    Therefore you cannot use a strategy whereby you create a page and hope that a link automatically becomes permanently invalid after a given time.

    Surely, the old link becomes permanently invalid, but upon refreshing the page, a new one pops up to the same PDF, video or audio. Which strategies are possible? You want visitors to be able to download your PDF. But you do not want them to share the link via social media or e-mail. If you set the expiring time to 10 minutes, the link is probably already expired by the time the link is posted on Facebook or Twitter.

    So, the only option is to go to your site and download it from there. This ensures that interested folks have to come to your site to get the content. The same goes for videos and audios. With expiring links, it is not possible to publish the link to the media on other sites or social media if you set the expiring time short enough.

    But visitors will be able to download files, view videos or listen to audios on your site for as often as they like, as long as they have access to the page. With streaming video, downloading it is not that easy and combined with an expiring URL, a technique called private streaming, you have two layers of protection against unauthorized use.

    What if I want to send a link via e-mail? Perfectly possible. You could send a link with a time limit of 3 days, for example. These desktop applications can generate a link for you very easily. How to sell content within a limited period If you want to sell videos, audios or tutorials, you can protect them with expiring links.

    But in order to protect the pages on which those links reside, you need a membership system which is capable of restricting access to pages via subscriptions.

    Most membership systems for WordPress or Joomla have the option to setup subscriptions with one-time access or for a certain period of time. Useful WordPress plugins for expiring links S3Media LinkSafe Lite , a free plugin which features downloadable links via S3 buckets and download distribution.

    The plugin comes with a tutorial how to set up your download distribution on AWS. S3Media Stream Enterprise , a commercial plugin to serve private streaming videos and audios, plus downloadable files via S3 buckets or download distributions. Useful Joomla extension for expiring links S3Media Stream regular , a commercial plugin to serve private streaming videos and audios, plus downloadable links via an S3 bucket.

    There are of course other plugins available, but the ones mentioned above provide excellent support with a long list of happy users, particularly related to setting up the AWS account which is not that straightforward for non-technical people.
