You need to use a program to calculate the hash.

On Windows you can use powershell. Open the directory containing the file in Explorer, in the Explorer menu go to File > Open Powershell. Then type

sha256sum.exe filename

. Obviously, you need to replace filename with the actual name of the file.

You don't need to do that if you're checking against your server's files.

hitsounds = {}
-- files to verify
local verifyfiles = {"sfx/player/hit1.wav", "sfx/player/hit2.wav", "sfx/player/hit3.wav"}

-- automatically get sums from server files
for _, path in ipairs(verifyfiles) do
	local sum = checksumfile(path)
	verifyfiles[sum] = true
end

addhook("team","hitsounds.team")
function hitsounds.team(id,team)
     if player(id,"team") == 0 then
          for _,path in ipairs(verifyfiles) do
               reqcld(id,4,path)
          end
     end
end

addhook("clientdata","hitsounds.clientdata")
function hitsounds.clientdata(id,mode,data1,data2)
     if mode == 4 and not verifyfiles[data2] then
          parse("kick "..id.." \"Você está usando um arquivo modificado!\"")
     end
end

Edit:

mrc was asking how to get a checksum, but edited his post.
