Businesses Using Millions of insecure SHA-1 Certificates

Experts at Netcraft discovered that nearly a million SSL SHA-1 certificates were signed with the potentially vulnerable SHA-1 hashing algorithm. Businesses Using Millions of Flawed Certificates, the news is shocking and refers the adoption of SHA-1 certificates, despite the algorithm is considered no more secure. Many big businesses, including firms like Deloitte, are still using SHA-1 certificates, […]

SHA-1 has been deprecated, what can I do?

The SHA-1 cryptographic hash algorithm has been known vulnerable, Collision attacks against it are too affordable and attacks will get cheaper soon. Many websites today are using digital certificates signed using algorithms based on the hash algorithm called SHA-1. Hashing algorithms are used to ensure the integrity of the certificate in the signing processes, a flawed […]
