Version Information

Will TrueCrypt be open-source and free forever? 
 
Yes, it will. We will never create a commercial version of TrueCrypt, as we believe in open-source 
and free security software.

Why is TrueCrypt open-source? What are the advantages? 
 
As the source code for TrueCrypt is publicly available, independent researchers can verify that the 
source code does not contain any security flaw or secret 'backdoor'. If the source code were not 
available, reviewers would need to reverse-engineer the executable files. However, analyzing and 
understanding such reverse-engineered code is so difficult that it is practically impossible to do 
(especially when the code is as large as the TrueCrypt code). 
 
Remark: A similar problem also affects cryptographic hardware. It is very difficult to reverse-
engineer it to verify that it does not contain any security flaw or secret 'backdoor'. 
 
 
 
TrueCrypt is open-source, but has anybody actually reviewed the source code? 
 
Yes. In fact, the source code is constantly being reviewed by many independent researchers and 
users. We know this because many bugs and several security issues have been discovered by 
independent researchers (including some well-known ones) while reviewing the source code. 
 
 
As TrueCrypt is open-source software, independent researchers can verify that the source
