Binaries

For executables use cat in | base64 -d | gunzip > a.out && chmod +x a.out, chmod is only required for linux binary.

• windows (mingw-w64 in path required): https://pastebin.com/36JyfcDh
• linux: https://pastebin.com/gN8C7HAC
• more sources are available in hints

If you need a windows binary but don’t have a linux subystem to decode it, lmk in the comments and I will provide the full executable.
