A code audit that is being carried out, using $60,000 that was raised on Indiegogo and Fundfill, revealed one or more serious security flaws that have not yet been revealed.( Something similar happened to secure email provider Lavabit, resulting in that company abruptly shutting down.) The developers were approached by the NSA or some other government agency to introduce a backdoor into the software, and decided to stop the project instead without breaching any gagging orders.The developers simply no longer wanted to continue the project.Many other possibilities have been suggested including: The reason given – that Microsoft has terminated support for Windows XP – appears to be a non sequitur unless you conclude that TrueCrypt was only intended to provide full disk encryption for operating systems that do not have it built in since Windows, OS X and versions of Linux (such as Ubuntu) do, the end of support for XP means that TrueCrypt is no longer needed. The unanswered question is why TrueCrypt was abandoned. The only version of TrueCrypt that is available for download on the site, version 7.2, is only good for decrypting existing data to carry out the migration process. The site provides instructions for migrating to BitLocker.

The top of TrueCrypt’s website was emblazoned with the following message in red: “WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues.” It also said development of TrueCrypt had ended after Microsoft terminated support for Windows XP and recommended that users of Windows 8, 7 and Vista migrate to Microsoft’s BitLocker disk encryption utility.

The anonymous developers of the free and hugely popular TrueCrypt disk encryption program dropped a bombshell at the end of May when they abruptly abandoned the project.
