[wix-users] Streaming Bootstrapper - HTTPS Certificate Verification?

[Raze, Leigh]

Is there a way for us to do this without using MSBuild?

The default for signtool.exe is SHA1 signatures.  I suspect this is also the case for other tools.  It is possible to:  1) double sign with SHA1 and SHA256; or 2) sign with just SHA256 (with the resulting incompatibility for XP, etc.).  The /fd switch on signtool.exe controls the "file digest" used to sign the target.  I am moving to using /fd SHA256 for all my products as we no longer support XP.

The e-mail below is from an external source.  Please do not open attachments or click links from an unknown or suspicious origin.

Our security team is requiring us to use HTTPS to download our MSIs and cabs. They brought up the question of Certificate Verification after we noticed that the embedded hashes are SHA-1, and not SHA-256 (which our security team was hoping for). Is there any way for us to have the Standard Bootstrapper use SHA-256 or perform Certificate Verification without modifying the source or build a custom bootstrapper.

Hello!

I am using the Standard Bootstrapper application to pull down, via HTTPS, a number of MSIs that we have built to install our product. This is working fine, but I have a security question related to the Standard Bootstrapper and giving DownloadUrl an HTTPS link:

Does anyone know if and how the Standard Bootstrapper does certificate validation on anything downloaded through HTTPS? I have looked through the source code for WiX and the Standard Bootstrapper and have not been able to find any leads. The only mention of certificates I have found is in the IIS Extension, which is not applicable to our product.

Thanks!
