TrueCrypt Ended Development, Using TrueCrypt Is Not Secure

Today I am not believing on the thing which I got to read in the early of the morning, and may many security enthusiasts have got the same reaction. The free whole-disk encryption suite TrueCrypt, which is one of the best and mine favorite tool for encrypting disk has gave a shocking announcement on its site.
The official site of TrueCrypt is redirecting the visitors to the program homepage on Sourceforge.net , which displays the following message-

WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues 

This page exists only to help migrate existing data encrypted by TrueCrypt.

The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP. Windows 8/7/Vista and later offer integrated support for encrypted disks and virtual disk images. Such integrated support is also available on other platforms (click here for more information). You should migrate any data encrypted by TrueCrypt to encrypted disks or virtual disk images supported on your platform.

 The page suggest the users to opt for Bitlocker, and page includes instructions for helping Windows users transition drives protected by TrueCrypt over to BitlLocker, the proprietary disk encryption program that ships with every Windows version since Vista.

Many of them is not believing with the announcement and rumoring that the redirection and announcement was a hoax. But as I have checked the WHOIS and DNS records, its showing a normal info and there is no substantive changes recently.

Matthew Green, who teaches cryptography at Johns Hopkins, researcher involved with the TrueCrypt audit, tweeted that he thinks the news is legitimate.
