tobat.bat is a batch file. It's part of the BatFramework project I'm making, but it's as easy as leaving it on your desktop.
Just drag and drop whatever file you want to turn into a batch file on top of it.
It uses certutil to convert the file into base64, then the batch file takes the certificate and modifies it to make it into perfection.
Of course you can do this in command line, but dragging and dropping is slightly easier.
tobat.bat is included as tobat.zip as an attatchment.
