This archive contains the source code of VeraCrypt. It is based on the original TrueCrypt 7.1a with security enhancements and modifications.
You may use the source code contained in this archive only if you accept and agree to the license terms contained in the file 'License.txt', which is included in this archive.
A detailed guide on how to build VeraCrypt on Windows can be found in the documentation in the repository and it is also available online.
The 64-bit editions of Windows Vista and later versions of Windows, and in some cases (e.g. playback of HD DVD content) also the 32-bit editions do not allow the VeraCrypt driver to run without an appropriate digital signature. Therefore, all .sys files in official VeraCrypt binary packages are digitally signed with the digital certificate of the IDRIX, which was issued by GlobalSign certification authority. At the end of each official .exe and .sys file, there are embedded digital signatures and all related certificates (i.e. all certificates in the relevant certification chain, such as the certification authority certificates, CA-MS cross-certificate, and the IDRIX certificate).
Keep this in mind if you compile VeraCrypt and compare your binaries with the official binaries. If your binaries are unsigned, the sizes of the official binaries will usually be approximately 10 KiB greater than the sizes of your binaries (there may be further differences if you use a different version of the compiler, or if you install a different or no service pack for Visual Studio, or different hotfixes for it, or if you use different versions of the required SDKs).
