SQLitePCLRaw is a Portable Class Library (PCL) for low-level (raw) access to SQLite. Packages named 'SQLitePCLRaw.provider.*' (like this one) are 'plugins' that allow SQLitePCLRaw.core to access the native SQLite library. This provider does DllImport of 'sqlite3mc', to reference the 'system' SQLite3 Multiple Ciphers. One common use for this provider is to access the SQLite3 Multiple Ciphers library installed from source.
