Can someone who downloaded yesterday please publish a sha256sum of the zip (or each file in the directory tree), for comparison with the github mirror?

I think I did this right. I ran `shasum -a 256` on the zip, but let me know if it doesn't look quite right.

For various reasons (at least, metadata and the .git folder) it's very unlikely that you'd get the exact same checksum for the entire zip... you'd need to post the sum for each file individually if you want to compare them.

This sounds entirely wrong to me. Checksums are used all the time to verify the integrity of archives.

The integrity of archives you're supposed to download from a site, not archives you're meant to create yourself.

If, in the director created when you unzipped this, you did:

find . |xargs shasum -a 256

And then posted the output, that would be helpful to people that want to verify these files.

Shasum 256 of the Mac zip titled 'f.lux-xcode-master.zip'

Thanks. This matches the mirror at http://www.dropbox.com/s/lcfbd7jqgyxq1au/f.lux-xcode-master.... (from a comment at http://www.idownloadblog.com/2015/11/12/f-lux-no-longer-be-s...)

I diffed the version on GitHub with the one downloaded from Dropbox (after verifying the Dropbox file's hash). The only changes to the GitHub version are the Readme file and that it was upgraded to target iOS 9.1, as well as some apparently minor changes in the XCode project file. So you won't get the same SHA sum, but all the files aside from those are the same. In particular, the "iflux" binaries are identical.

So it looks like the GitHub version matches the original.

Can confirm. Did the same

github version of iflux looks ok for me too:

  $ cd f.lux-master/
  $ shasum -a 256 iflux | grep 10428983a681b07f687511e150f46e39b6f9da506316a8041742a78bc0ce9ef6
  10428983a681b07f687511e150f46e39b6f9da506316a8041742a78bc0ce9ef6  iflux

You say that it was upgraded to target iOS 9.1. Was the version I downloaded and SHA summed not the 9.1 build?

I'm not 100% sure. The version from Dropbox has some differences in the Xcode project file, including a different "target version". The Dropbox version says it targets 8.0.

Ah ya I just change that when going through the compiling steps in Xcode.
