About Certificate Errors In Internet Explorer

About Certificate Errors In Internet Explorer – As of yesterday, after updating the year 2017. May. After Patch Tuesday, Microsoft browsers such as Edge and Internet Explorer began marking websites as secure if they use SSL/TLS certificates signed with the SHA-1 algorithm.

This comes after Mozilla banned SHA-1 signed certificates in Firefox 51 and Google Chrome 56, both versions of the browser released in 2017. the month of January

The reasons these three major browsers banned SHA-1 originally came from research published in the fall of 2015 that revealed that the financial and computational cost of breaking SHA-1 was lower than anyone thought.

That fall, browser vendors agreed to a long-term plan to remove SHA-1 signed certificates from the Internet. The first important step was taken in 2016. on January 1, when publicly trusted certificate authorities banned the issuance of new certificates signed with the SHA-1 algorithm.

The last step of this process was in 2017. in January, when all browser manufacturers agreed not to trust all SSL/TLS certificates signed with the SHA-1 algorithm. This meant that browsers would display an error when a user tried to navigate to an HTTPS site that encrypted communications using an SSL/TLS certificate signed with SHA-1.

Microsoft was late to the party, but now the company has joined Google and Mozilla in that stance.

The decision could not have been made earlier, because it was on February 23, 2017 that Google and other researchers announced the SHA-1 collision attack.

For their research, Google created two different files with the same SHA-1 digital signature. Since SSL/TLS certificates are just files, this meant that, at least in theory, someone could create two SSL/TLS certificates with the same SHA-1 hash and pretend they were legitimate websites. Fortunately, by then Google and Mozilla were showing bugs when accessing these types of sites.

May 2017. In a security advisory issued on Patch Tuesday, Microsoft explains its decision to ban SHA-1 signed certificates in Edge and Internet Explorer and encourages website owners to use SHA-2 signed certificates.

SHA-1 is an algorithm developed by NSA researchers in the 1990s that has been used to digitally sign files or data streams in recent decades. In the mid-2000s, after it became clear that someone could theoretically crack a SHA-1 hash, security experts began advising organizations to use SHA-2 or stronger hash functions to create digital signatures for sensitive files.

This may be because some APIs require the use of HTTPS to ensure secure data transfer (Flickr is a good example). Or maybe you want your local environment to be a bit more in line with your production environment (where you should definitely be using HTTPS). Next, you need to use an SSL certificate on your local computer.

For on-site purposes, we generally do not need the actual certificate that we use at our production site. A self-signed certificate should also do the job. Creating a self-signed certificate is not difficult, as there are several ways to do it (for example, see here).

For Windows users, you should probably consider Microsoft web browsers (Microsoft Edge, available since Windows 10 and Internet Explorer 11). You may be wondering why the self-signed certificate does not work well in Edge and Internet Explorer, but works well in other web browsers like Google Chrome and Mozilla Firefox.

Microsoft Edge and Internet Explorer do not trust self-signed certificates for security reasons, which is a good thing. Any web browser should do this (and probably all modern browsers do) because of the risk of the client talking to a fake server (see this article for a more detailed explanation).

But when you need to trust a self-signed certificate you’ve created because you need it for local development, the process is pretty easy in browsers like Chrome or Firefox. However, relying on Edge or Internet Explorer is not so trivial. In this article, I’ll show you how to get your self-signed SSL certificate working in Edge and IE11. Note that we are not talking about the new Edge browser, which is based on Chromium and therefore more closely resembles Google Chrome.

If you want to trust the self-signed certificate in both Edge and Internet Explorer, you need to do the following in Internet Explorer, even if it only has to accept Edge, because I couldn’t get it to work from Edge.

These should be all the steps to get your self-signed SSL certificate working in Microsoft Edge and Internet Explorer. The process is a bit more complicated than in other web browsers, but it’s still manageable and you only need to do it once for this certificate to work in Edge and Internet Explorer. Do you know of another way to get self-signed certificates to work in Internet Explorer or Microsoft Edge? Let me know in the comments.
