Vulnerable CA Certificate Check Tool

Short after the publication that several Certificate Authorities are using a weak signature algorithm for signing purposes Networking4all -- the largest SSL reseller in the Benelux -- announces a tool to check if your certificate is affected by an insecure signature somewhere in the certificate chain.

A web browser displays a tiny image of a padlock when a user has a secure connection to a web site. This is intended to provide evidence that the Web site is legitimate, as the browser and the site exchange digital certificates provided by a Certificate Authority -- a trusted third party.

This team of computer security researchers have proven they can create fake certificates that will be accepted by the security system.

You can check if a certificate in the chain has been signed with a insecure algorithm using the Vulnerable CA Check tool provided by Networking4all.
