How I Compiled TrueCrypt For Windows and Matched the Official Binaries 250

First time accepted submitter xavier2dc writes "TrueCrypt is a popular software enabling data protection by means of encryption for all categories of users. It is getting even more attention lately following the revelations of the NSA as the authors remain anonymous and no thorough security audit have yet been conducted to prove it is not backdoored in any way. This has led several concerns raised in different places, such as this blog post, this one, this security analysis [PDF], also related on that blog post from which IsTrueCryptAuditedYet? was born. One of the recurring questions is: What if the binaries provided on the website were different than the source code and they included hidden features? To address this issue, I built the software from the official sources in a careful way and was able to match the official binaries. According to my findings, all three recent major versions (v7.1a, v7.0a, v6.3a) exactly match the sources."
