crypting part of the configuration

[lucamorelli]

Hi,
the actual configuration architecture is interesting but so far I see that a interesting Feature of the actual asp.net Runtime is missing, the feature to crypt part of the configuration.
this Feature is quite useful,. because sometimes I need to place in the configuration sensible data, as POS authentication credentials, but I would like to make safe the data in the case of unauthorized access.
How can I handle this?
