Reading a Rijndael encrypted connection string from a Windows registry

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monk brethren,

I have a dilema that I hope someone can provide divine guidance to. I am in a mixed environment of .NET and Perl in which a connection manager rights Rijndael encrypted connection strings to the windows registry, all connection information must be entered through this connection manager as dictated by security. What I need to do is extract this connection string information for my Perl scripts in order to conduct log parsing and entry into a database.

I've looked at the CPAN module Data::Encrypt but I'm not sure that it will provide me the necessary algorithm to decrypt the Rijndael encrypted registry keys.

Does any one have any ideas or have I enter the dark realm of .NET specific encryption algorithms. All prayers welcome.

I couldn't find a "Data::Encrypt" module, but there is a Data::Encrypted module. That one works with RSA, which is for public-key crypto. Not what you want. There is a Crypt::Rijndael module. You will also need to know if the data was encrypted in a specific cipher mode (probably CBC mode, if it was), in which case you'll need a module that can handle that mode, like Crypt::CBC. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer `: () { :\|:& };:` Note: All code is untested, unless otherwise stated	[reply] [d/l]
