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.

BitLocker Security Modes
BitLocker can function in different modes which provide different levels of security. Which mode you choose depends on whether you have a Trusted Platform Module (TPM) on your computer and the level of security you want to achieve. The TPM is a secure device built into the hardware of the computer to store cryptographic (encryption) keys. Different security modes can combine the usage of a TPM, a PIN number and a startup key. A startup key is a cryptographic file that is stored on a separate USB file. Go here for more info about the security levels of BitLocker.
