This dynamic linking library serves as a resource of functions and methods for the CNG Key Isolation Service - this service is a genuine part of MS Windows Key Storage and Retrieval functionalities :
"CNG currently supports the storage of asymmetric private keys by using the Microsoft software KSP that is included with Windows Server 2008 and Windows Vista and installed by default. CNG stores the public portion of the stored key separately from the private portion. The public portion of a key pair is also maintained in the key isolation service and is accessed by using local remote procedure call (LRPC). The key storage router uses LRPC when calling into the key isolation process. All access to private keys goes through the private key router and is audited by CNG."
