Please create detached signatures for the binaries we will upload to GitHub for the `butane` 2.23.0 release. This is a manual process for now, pending the automation discussed in https://pagure.io/robosignatory/issue/53 and https://github.com/coreos/fedora-coreos-tracker/issues/335.

The binaries themselves have been built in koji. Here is a small script to grab all of the rpms and the files out of the rpms and name them appropriately:

```
#!/bin/bash
set -eux -o pipefail

1. Use the Fedora 40 key for the detached signatures
   KEYTOSIGNWITH='fedora-40'

VR='2.23.0-1.fc40'
RPMKEY='a15b79cc' # Fedora 40 key

do_sign() {

1. Sign with sigul unless FAKESIGN=1
   if [ ${FAKESIGN:-0} != 1 ]; then
   sigul sign-data -a $KEYTOSIGNWITH "$1" -o "$1.asc"
   else
   echo INVALID > "$1.asc"
   fi
   }

1. Grab the binaries out of the redistributable rpm
   rpm="butane-redistributable-${VR}.noarch.rpm"
   koji download-build --key $RPMKEY --rpm $rpm
   rpm -qip $rpm | grep -P "^Signature.*${RPMKEY}$" # Verify the output has the key in it
   rpm2cpio $rpm | cpio idv './usr/share/butane/butane*'

1. Rename the binaries
   mv usr/share/butane/butane-aarch64-apple-darwin \
   butane-aarch64-apple-darwin
   mv usr/share/butane/butane-aarch64-unknown-linux-gnu-static \
   butane-aarch64-unknown-linux-gnu
   mv usr/share/butane/butane-ppc64le-unknown-linux-gnu-static \
   butane-ppc64le-unknown-linux-gnu
   mv usr/share/butane/butane-s390x-unknown-linux-gnu-static \
   butane-s390x-unknown-linux-gnu
   mv usr/share/butane/butane-x86_64-apple-darwin \
   butane-x86_64-apple-darwin
   mv usr/share/butane/butane-x86_64-pc-windows-gnu.exe \
   butane-x86_64-pc-windows-gnu.exe
   mv usr/share/butane/butane-x86_64-unknown-linux-gnu-static \
   butane-x86_64-unknown-linux-gnu

1. Sign them
   do_sign butane-aarch64-apple-darwin
   do_sign butane-aarch64-unknown-linux-gnu
   do_sign butane-ppc64le-unknown-linux-gnu
   do_sign butane-s390x-unknown-linux-gnu
   do_sign butane-x86_64-apple-darwin
   do_sign butane-x86_64-pc-windows-gnu.exe
   do_sign butane-x86_64-unknown-linux-gnu

1. Fix permissions and clean up
   chmod go+r *.asc
   rm $rpm; rmdir ./usr/share/butane; rmdir ./usr/share; rmdir ./usr
   ```

After running this you should end up with a directory with files in it like:

```
$ ls -1
butane-aarch64-apple-darwin
butane-aarch64-apple-darwin.asc
butane-aarch64-unknown-linux-gnu
butane-aarch64-unknown-linux-gnu.asc
butane-ppc64le-unknown-linux-gnu
butane-ppc64le-unknown-linux-gnu.asc
butane-s390x-unknown-linux-gnu
butane-s390x-unknown-linux-gnu.asc
butane-x86_64-apple-darwin
butane-x86_64-apple-darwin.asc
butane-x86_64-pc-windows-gnu.exe
butane-x86_64-pc-windows-gnu.exe.asc
butane-x86_64-unknown-linux-gnu
butane-x86_64-unknown-linux-gnu.asc
```
