The end for 1024-bit SSL certificates is near, Mozilla kills a few more
Website owners take notice: In weeks, Mozilla products including its popular Firefox browser will stop trusting an unknown number of SSL certificates that were issued using old root CA certificates with 1024-bit RSA keys.
The move is part of the organization’s efforts that started in September to force certificate authorities (CAs) and their customers to stop using 1024-bit certificates, which are considered cryptographically unsafe because of advances in computing power.
“If you manage an SSL-enabled website, this change will not impact you if your certificates and the certificates above it have 2048-bit keys or more,” the Mozilla security engineering team said Wednesday in a blog post. “If your SSL certificate has a 1024-bit key, or was issued by a certificate with a 1024-bit key, then you will need to get a new SSL certificate, and update the certificates in your Web server.”
