Password Filter for Win2k3/Win2k8(repost)(repost)

I'm looking for a Windows password filter which will work for Win2k3/Win2k8 and can write encrypted/unencrypted passwords (and all relevant information) to: - A database (rows follow the format of the struct) - A XML file (using the appropriate struct) Encryption should use RSA and retrieve the private/public key information in the local keystore. - Require filter to write debugging information to the System Event Log and/or log file based on the value of a debugging registry key \Written in C (don't believe this can be written using managed code, but if it can, C# is my preference). - Require unit tests - Require NSIS based installer (I can assist with this) Sincerely, Adam
