Update your cryptographic settings before August Patch Tuesday!
August’s Patch Tuesday is an important one, I would say critical! Patch Tuesday is usually the second Tuesday of each month, on which Microsoft releases security patches. A security fix or enhancement will be released which will block all applications that use cryptographic keys less than 1024 bits.
To further reduce the risk of unauthorized exposure of sensitive information, Microsoft has created a software update that will be released for the following operating systems: Windows XP, Windows Server 2003, Windows Server 2003 R2, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. This update will block the use of cryptographic keys that are less than 1024 bits.
