SHA-2 code-signing on old Windows 7 SP1 machines

[NewsArchive]

All,

if you still have to support SHA-2 code-signing on older Windows 7 machines,
the following might help.

To handle SHA-2 code-signing (including SHA-2 time-stamping) on Windows 7
SP1 you need:

1. SetupBuilder 10.

2. Windows 7 SP1.

3. SignTool.exe version 6.1.7000.0.

4. Microsoft Capicom installed and registered.

You can use the following tool to install Capicom:

Note 1: you can't use SIGNTOOL.EXE Version 6.1.7000 to handle dual
SHA-1/SHA-2 code-signing. Only SHA-2 signing works.

Note 2: it all depends on the Windows OS patch level. Some more information

Hope this helps.

But if you have 6.3.9600 you can.

Yes and no <g>. The main problem with 6.3.9600 and Windows 7 is that you
need a very *very* specific patch level to get it to work with SHA-2
(timestamping). On most machines SIGNTOOL 6.3.9600 crashes or does not
create a valid SHA-2 timestamp.

Hi Friedrich,

My findings on Win7 with SIGNTOOL 6.3.9600 are that SHA256 is corrected
generated but kills the previously created SHA1. What is the asset of having
both SHA1 as well as SHA256 anyway?

Only SetupBuilder 10 can handle "dual" code-signing. Previous SB versions
do not know nothing about dual code signatures.

BTW, my previous screenshot taken on a Windows 7 machine shows a GPF when
code-signing a file with SHA-2 and adding a required SHA-2 timestamp. It
works fine with SIGNTOOL 6.3.9600 using a non-SHA-2 timestamp or no
timestamp at all.

You need at least a SHA-2 signature with a SHA-2 timestamp. Or better, a
SHA-1 signature with SHA-1 timestamp *and* SHA-2 signature with SHA-2
timestamp (aka "dual" code-signed).

See? I always KNEW I was special.... or is that spatial?

All I can report is that the current, and static (no updates), Win7 I
use handles it... as to exactly WHY, beats me!<g>

If memory serves I did have to jump through some hoops and install a
few things to make it work but I have no idea what they were.
