How Killing SSL SHA-1 Certificate Can Make the Web Safer?

SSL SHA-1 Certificate

Companies running online businesses need to ensure that they are using a secure algorithm, which will promote safe user experience. Many websites are secured with SSL encryption, a certificate that defines the level and strength of web security. Along with that, 90% of websites use SHA-1 certificates, an algorithm implemented to keep the identity of the website from being impersonated.

What is SHA-1?

This certificate ensures that you are visiting an authentic website and not landing on any fraudulent page. For example, when you go to Google account, the algorithm encrypts your message and makes certain that you login to the real Google website and not a just leave your password at a fake site.

However, according to researches, the SHA-1 algorithm is proven extremely weak and highly susceptible to hackers attack. With all the given fact, many companies are still using it widely. This might result in forging SHA-1 certificate, which will further put the website users’ sensitive information at risk. Thus, to prevent all of this from literally happening, SHA-1 certificate needs to be upgraded.

SHA-2 is a potent replacement of SHA-1 certificate and upgrading the older version can protect end users from hacker’s attack. Even Google has taken initiative to warn users about the insecurity by displaying a warning on Chrome browser, every time a visitor lands on a SHA-1 SSL enabled site. It is expected that if browsers initiate this deprecation plan, all companies will take a step ahead in upgrading their certificates eventually.


Many companies are taking measures to upgrade their SHA-1 certificates, but this should have started years ago. Security should be every organization’s priority, as you need to protect your users from potential cyber threat. Thus, companies need to keep a check on their web security certificates and upgrade their website frequently for making web safer and for their own good.
