<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>
<meta name="description" content="VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/>

    <p> With the sign_test.bat script you just signed the VeraCrypt executables. This is necessary, since Windows only accepts drivers, which are trusted by a signed Certificate Authority. <br>
	Since you did not use the official VeraCrypt signing certificate to sign your code, but a public development version, you have to import and therefore trust the certificates used.
		<ol>
			<li>
				Open the folder "src/Signing"
			</li>
			<li>
				Import the following certificates to your Local Machine Certificate storage, by double clicking them:
				<ul>
					<li>GlobalSign_R3Cross.cer</li>
					<li>GlobalSign_SHA256_EV_CodeSigning_CA.cer</li>
					<li>TestCertificates/idrix_codeSign.pfx</li>

					<li>TestCertificates/idrix_SHA256TestRootCA.crt</li>

				<b>This distribution package is damaged</b> <br>
				<img src="CompilingGuidelineWin/DistributionPackageDamaged.jpg" width="20%"> <br>
				On Windows 10 or higher you might get the error message above. In order to avoid this, you will need to:<br>
				<ul>
					<li>Double-check the installation of the root certificate that issued the test code signing certificate in the "Local Machine Trusted Root Certification Authorities" store.</li>
					<li>Compute SHA512 fingerprint of the test code signing certificate and update the gpbSha512CodeSignCertFingerprint array in the file "src/Common/Dlgcode.c" accordingly.</li>
				</ul>
				Please see <a href="https://sourceforge.net/p/veracrypt/discussion/technical/thread/83d5a2d6e8/#db12" target="_blank">https://sourceforge.net/p/veracrypt/discussion/technical/thread/83d5a2d6e8/#db12</a> for further details.<br>
				<br>
				Another approach is to disable the signature verification in the VeraCrypt code. This should be done only for testing purposes and not for production use:
				<ol>
					<li>
						Open the file "src/Common/Dlgcode.c"
					</li>
					<li>
						Look for the function "VerifyModuleSignature"
					</li>
					<li>
						Replace the following lines: <br>
						Find:<br>
						<p style="font-family: 'Courier New', monospace;">
						if (!IsOSAtLeast (WIN_10)) <br>
						return TRUE;
						</p> <br>
						Replace:<br>
						<p style="font-family: 'Courier New', monospace;">
						return TRUE;
						</p>
					</li>
					<li>
						Compile the VeraCrypt code again
					</li>

				<b>Driver Installation Failure during VeraCrypt Setup from Custom Builds</b> <br>
				<img src="CompilingGuidelineWin/CertVerifyFails.jpg" width="20%"> <br>
				Windows validates the signature for every driver which is going to be installed.<br>
				For security reasons, Windows allows only drivers signed by Microsoft to load.<br>
				So, when using a custom build:<br>
				<ul>
					<li>If you have not modified the VeraCrypt driver source code, you can use the Microsoft-signed drivers included in the VeraCrypt source code (under "src\Release\Setup Files").</li>
					<li>If you have made modifications, <strong>you will need to boot Windows into "Test Mode"</strong>. This mode allows Windows to load drivers that aren't signed by Microsoft. However, even in "Test Mode", there are certain requirements for signatures, and failures can still occur due to reasons discussed below.</li>
				</ul>
				Potential Causes for Installation Failure under "Test Mode":
				<ol>
					<li>
						<b>The certificate used for signing is not trusted by Windows</b><br>
						You can verify if you are affected by checking the properties of the executable:
						<ol>
							<li>
								Make a right click on the VeraCrypt Setup executable: "src/Release/Setup Files/VeraCrypt Setup 1.XX.exe"
							</li>
							<li>
								Click on properties
							</li>
							<li>	
								Go to the top menu "Digital Signatures". Her you will find two signatures in the Signature list
							</li>
								Check both by double clicking on it. If the headline says "The certificate in the signature cannot be verified", the corresponding signing certificate was not imported correctly.<br>
								Click on "View Certificate" and then on "Install Certificate..." to import the certificate to Local Machine certificate storage. For the Root certificates, you may need to choose "Place all certificates in the following store", and select the "Trusted Root Certification Authorities" store.<br>
								<img src="CompilingGuidelineWin/CertificateCannotBeVerified.jpg" width="40%"> <br>
							<li>
						</ol>
					</li>
					<li>
						<b>The driver was modified after the signing process.</b> <br>
						In this case, please use the script "src/Signing/sign_test.bat" to sign your code again with the test certificates
					</li>
				</ol>
			</li>
		</ul>
