What is strong key in dot net

Did you try google? I did:

http://en.wikipedia.org/wiki/Strong_key[^].

It even has some nice references to CP[^]:

Strong Names Explained[^]
Building Security Awareness in .NET Assemblies : Part 3 - Learn to break Strong Name .NET Assemblies[^]

And to MSDN also: http://msdn.microsoft.com/en-us/library/wd40t7ad.aspx[^].

Hope I'm not bothering you with all that information.
