 // Stores client pairing information in Windows registry. Two separate registry
 // keys are used:
 //  - |privileged| - contains the shared secrets of all pairings. This key must
 //                   be protected by a strong ACL denying access to unprivileged
 //                   code.
 //  - |unprivileged| - contains the rest of pairing state.
 //
 // Creator of this object is responsible for passing the registry key handles
 // with appropriate access. |privileged| may be NULL if read-only access is
 // sufficient. Shared secrets will not be returned in such a case.
