TrueCrypt let its users know that it would be discontinuing services abruptly by redirecting its website to a message on SourceForge.net, a web-based source code repository. The sudden discontinuation has surprised users and security experts alike.
TrueCrypt was an open source freeware utility that allowed its users to fully and easily encrypt data on their hard disks. It was released in 2004 by anonymous developers. They have never identified themselves in the 10 years the TrueCrypt has been active and still remain unidentified.
The end of life announcement came as a short message posted on TrueCrypt's SourceForge page that read "WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues." It also urged users to other alternative like Windows Bit Locker. No other reason has been stated for the sudden and bizarre demise of TrueCrypt.
We strongly suggest any TrueCrypt users seek out alternatives as soon as possible. Users should also take precautions and have the GoTrusted VPN service running anytime they're sending or receiving data. These steps will be the best way to insure your privacy is maintained.
