[Vm-dev] CryptographyPlugins

[Levente Uzonyi]

Hi all,

I've fixed the parameter validation of all plugins in the 
CryptographyPlugins package[1] and removed SHA256Plugin[2] because
SHA2Plugin does the same and more.
I ran the tests of the Cryptography package on my machine (64-bit linux)
and all of them passed (except for those using SHA256Plugin obviously).
Please review and test the code, and if everything looks good, I suggest 
adding all plugins as external to the official VMs.
