Internet Explorer Help Certificate Errors

Internet Explorer Help Certificate Errors – As of yesterday, through the updates sent in the May 2017 Patch Tuesday, Microsoft browsers such as Edge and Internet Explorer have started showing websites as secure if they use SSL/TLS certificates signed with the SHA-1 algorithm.

The move comes after Mozilla banned self-signed SHA-1 certificates in Firefox 51, and Google in Chrome 56, both browser versions released in January 2017.

The reasons why all three of these major browsers have banned SHA-1 is basically due to a study published in the fall of 2015, which shows that the economic and computational costs of breaking SHA-1 are low, beyond anyone’s imagination.

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

The final step in this process was in January 2017, when all browser manufacturers agreed to trust all SSL/TLS certificates signed with the SHA-1 algorithm. This means that browsers will display an error message when a user tries to navigate to an HTTPS website that encrypts communications using an SSL/TLS certificate signed with SHA-1

Microsoft was late to this party, but now the company is in line with Google and Mozilla at this booth.

The decision could not have come sooner, since Google and other researchers announced the first SHA-1 attack on March 23, 2017.

For their research, Google generated two different files with the same SHA-1 digital signature. Since SSL/TLS certificates are nothing more than files, this means, at least in theory, that one can create two SSL/TLS certificates with the same SHA-1 hash, and make the right points. Fortunately, at that time, Google and Mozilla were already showing errors when opening such sites.

In a security advisory following the May 2017 update on Tuesday, Microsoft explained its decision to ban self-signed SHA-1 certificates in Edge and Internet Explorer, and encouraged website owners to opt out of using the documents – SHA-2 validated certificate.

SHA-1 is an algorithm created by NSA researchers in the 90s that has been used in recent decades to create digital signatures for files or data streams. When it became clear in the mid-2000s that anyone could theoretically break SHA-1 hashes, security experts began suggesting that organizations use SHA-2 or stronger hashing services to create digital signatures for sensitive files.
