Description
The .zip file above includes a Plugin for NSIS (DcryptDll.dll) and two executable
binaries (Ncrypt.exe & GenKeys.exe), the source to build all 3, two example
.nsi scripts showing possible usage, the how to use document DcryptDllReadme.html,
and a couple of other supporting files.
These add some encryption / decryption capability to NSIS.
In a manner similar to the ExtractDllEx plugin, one program is used on the computer
you are compiling your NSIS script on to do the encryption, and the plugin
is used to do the decryption when the Installer .exe is actually executing.
Ncrypt.exe is the program you use for the encryption, DcryptDll.dll is the plugin used to
do the decryption.
The NGenKeys.exe is not necessary, but is included for convenience: you can use it
to generate the KeyStrings you will need for encrypting and decrypting the files.
The zip file was built so that you can just extract it (preserving folder names) to your
NSIS distribution Contrib folder. You should either move the plugin to the Plugins
folder or recompile the source (the VC++ 6.0 project file has output set to the Plugins directory).
You can move Ncrypt.exe and NGenKeys.exe to some folder included in your PATH environment variable
or whatever.
Please let me know if you find any of those "dreaded" bugs.
