            Bug ID: 62696
           Summary: Consider use of sha256 for signing of .exe files of
                    Tomcat installer.
           Product: Tomcat 9
           Version: 9.0.x
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Packaging
          Assignee: dev@tomcat.apache.org
          Reporter: knst.koli...@gmail.com
  Target Milestone: -----

Reviewing release candidates of Tomcat 8.5.34, 9.0.11,
apache-tomcat-8.5.34.exe
apache-tomcat-9.0.12.exe

are both signed with sha1 signatures.

I mean the following:
In Windows: open File Explorer, right-click on the file to open a menu, click
"Properties" item in the menu. In the file properties dialog see "Signatures"
tab. The file signature is listed there as "sha1".


An example of a OSS installer that has sha256 signature, "Git for Windows":
https://github.com/git-for-windows/git/releases/tag/v2.18.0.windows.1
-> PortableGit-2.18.0-64-bit.7z.exe

An older version of "Git for Windows" had both sha1 and sha256 signatures:
https://github.com/git-for-windows/git/releases/tag/v2.12.0.windows.1
-> PortableGit-2.12.0-64-bit.7z.exe


I first mentioned this issue 1,5 years ago. I am filing it into Bugzilla, as
release signing policy at ASF has changed recently to avoid sha-1.
