Microsoft Strengthens RSA Key Acceptance Standards

(Ping! Zine Web Tech Magazine) – A big change is coming to the way Microsoft handles patches. According to a recent report from Sophos, the company is changing its certificate acceptance standards, now requiring digital certificates with RSA keys to contain 1024 bits or higher.

The implementation of the change precedes the company’s highly anticipated release of Windows 8 next month.

“512-bit RSA keys were factored in 1999, while RSA 768 was factored in 2009. The reasonable conclusion is that these ciphers are no longer safe from snooping and need to be retired,” commented Chester Wisniewski of Sophos when discussing the matter via the company’s blog.

In June, the Windows creator moved to revoke certificates pertaining to the now infamous Flame virus mostly affecting Middle-Eastern countries including Iran.
