Latest version of Microsoft IE and EDGE will no longer support SHA-1 Certificate Encrypted Websites

SSL Error in Microsoft Internet Explorer

Finally, Microsoft has turned on the green signal to quit its support for SHA-1 SSL certificate encrypted website.

As the number of cyber-attacks is increasing day by day, SSL certificate authorities, Web browsers, and Operating systems, etc. platforms are worried about the privacy and security of their users and customers. By taking this matter seriously, Google Chrome and Mozilla Firefox has already started not to accept the encrypted session with SHA-1 Certificate.

Microsoft thinks, user’s information security is at a high risk if they continue to support SHA-1 encryption, so they took this concern very seriously and during the new patch release of Internet Explorer and EDGE, they have strictly determined to quit SHA-1 SSL certificate support and to alert users with a message.

Today, SHA-1 encrypted SSL certificates are considered as the weak protocol to encrypt any information over the web, collision attacks number are increased and the study shows that the hacking of SHA-1 encrypted website is quite easy for cyber criminals.

Along with Chrome and Firefox, now Microsoft IE has now dropped the support of SHA-1 Encryption.

As per the new policy of Microsoft for IE users, the website which is using SSL certificate to encrypt information must have to use the latest SHA-2 encryption algorithm.

The new IE update reveals that it will not load the website pages which are using SHA-1 encryption.
