A code-signed binary can be found here.
You can pick any of the .exe files there, they should be code-signed. If not, let me know. I also include detached PGP signatures (the .asc files) and the latest build will always be available under the name premake4.exe.
Hope it helps someone.

PS: yes, this was mainly built for use in the WDS repo and therefore is located in the windirstat/premake-stable project realm.
PPS: previously I had given the SHA1 hash here for the build from rev 800. Since I am updating this every now and then, please check that the file is code-signed or check that the PGP signature is valid. Thanks.
