Download go_rcsa 1.0.0

go_rcsa has no login: anyone who can reach its port has full access. Keep it on 127.0.0.1, as the steps below do, so other machines can't reach it.

You don't need administrator rights to install or update go_rcsa on any of these systems.

Windows

1. Download go_rcsa-1.0.0-windows-amd64.exe and install-windows.ps1 into the same folder.
2. Open PowerShell in that folder and run:

   powershell -ExecutionPolicy Bypass -File install-windows.ps1

3. Start go_rcsa from the Start menu, then open http://127.0.0.1:8080/ in a browser.

macOS

macOS 12 or later. Choose darwin-arm64 for Apple Silicon (M1 and later) or darwin-amd64 for Intel. If you're not sure, run uname -m in Terminal: arm64 means Apple Silicon and x86_64 means Intel.

1. Download the file, then in Terminal install it from your Downloads folder. This example is for Apple Silicon; use darwin-amd64 on Intel:

   cd ~/Downloads
   mkdir -p ~/.local/bin ~/.local/share/go_rcsa
   install -m 755 go_rcsa-1.0.0-darwin-arm64 ~/.local/bin/go_rcsa
   xattr -d com.apple.quarantine ~/.local/bin/go_rcsa

   go_rcsa isn't notarized by Apple, so macOS won't open it until that last line clears its download mark. If xattr answers No such xattr, that's fine.

2. Start it from the folder that will hold its database:

   cd ~/.local/share/go_rcsa
   ~/.local/bin/go_rcsa -listen-addr 127.0.0.1:8080

3. Open http://127.0.0.1:8080/ in a browser.

Linux

1. Download go_rcsa-1.0.0-linux-amd64 and move it to a folder you own:

   mkdir -p ~/.local/bin ~/.local/share/go_rcsa
   install -m 755 go_rcsa-1.0.0-linux-amd64 ~/.local/bin/go_rcsa

2. Start it from the folder that will hold its database:

   cd ~/.local/share/go_rcsa
   ~/.local/bin/go_rcsa -listen-addr 127.0.0.1:8080

3. Open http://127.0.0.1:8080/ in a browser.

Updates

You only install by hand once. After that, Utilities → Updates in go_rcsa finds new releases, checks their signature, backs up the SQLite database and installs them. This only works if you can write to the folder holding the program, so don't install it under C:\Program Files, /Applications or /usr/local.
