| Occasionally downloads fail, so this (Lua) script here lets you check the download of MUSHclient against a supplied MD5 hash.
name = utils.filepicker ("Choose file", "mushclient*.exe", "exe",
{ exe = "MUSHclient installers" } )
if name then
f = io.open (name, "rb")
if f then
print ("sumcheck =", utils.tohex (utils.md5 (f:read ("*a"))))
f:close ()
end -- if opened file ok
end -- if have name
For example, run against mushclient378.exe (the installer itself) I got:
sumcheck = A6DB5E2A12B90344D30B9566A7FAB19D

| You can make an alias to do the same thing:
<aliases>
<alias
match="md5sum"
enabled="y"
send_to="12"
sequence="100"
>
<send>name = utils.filepicker ("Choose file", "mushclient*.exe", "exe",
{ exe = "MUSHclient installers" } )
if name then
f = io.open (name, "rb")
if f then
print ("sumcheck of", name, "=", utils.tohex (utils.md5 (f:read ("*a"))))
f:close ()
end -- if opened file ok
end -- if have name
</send>
</alias>
</aliases>
Just type "md5sum" and it will prompt you for the file to check. |

| And if you prefer not to use Lua as your main scripting language, just save the stuff below and make a plugin:
 |
To save and install the Installer_sumcheck plugin do this:
- Copy between the lines below (to the Clipboard)
- Open a text editor (such as Notepad) and paste the plugin into it
- Save to disk on your PC, preferably in your plugins directory, as Installer_sumcheck.xml
- Go to the MUSHclient File menu -> Plugins
- Click "Add"
- Choose the file Installer_sumcheck.xml (which you just saved in step 3) as a plugin
- Click "Close"

* Type 'md5sum' to activate.
* Navigate to the mushclientXXX.exe file you downloaded.
(The XXX will be the version number).
* Click 'Open'.
The resulting message (in the output window) will show you the sumcheck.
This should agree with the sumcheck shown on the web page announcing the MUSHclient version.

| You may have problems running this if you have the default Lua "sandbox" as that disables files being read/written. To fix that, use the File menu -> Global Preferences -> Lua and search for the lines:
-- default is to sandbox everything --
MakeSandbox () --> remove this line to remove protection
Change that to:
-- sandbox everything except the installer sumcheck plugin --
if GetPluginID () ~= "4a267cd69ba59b5ecefe42d8" then -- Installer_sumcheck
MakeSandbox ()
end -- if

| An alternative approach is to download the md5sum program. Here are some locations where I found a copy. md5.zip includes source code. You can verify the md5sum.exe program against itself using the sumchecks below:
The file md5sum.exe is 48 Kb in size.
http://etree.org/cgi-bin/counter.cgi/software/md5sum.exe eb574b236133e60c989c6f472f07827b
http://theopencd.sunsite.dk/md5sum.exe eb574b236133e60c989c6f472f07827b
http://www.fourmilab.ch/md5/md5.zip b14e189e965e5ed523282d3c8ee6c945
http://downloads.activestate.com/contrib/md5sum/Windows/md5sum.exe eb574b236133e60c989c6f472f07827b
Then just open a command (console) window, navigate to where you have put the mushclient installer, and type something like this (depending on the version):
c:\> md5sum mushclient378.exe
a6db5e2a12b90344d30b9566a7fab19d *mushclient378.exe
The result is the same as before (the upper-case/lower-case difference is not relevant). |
