Description

The purpose of this project is to demonstrate how NSIS coding could be useful beyond the traditional creation of an installation.
We use here some of the useful nsis Functions & Macros and the md5 plugin to create a fancy stand alone gui that implements md5dll and generates a md5 value from contents of specified file.

• Applies to NSIS 2.15
