Random number gathering daemon which creates a /dev/hwrandom
While running the daemon creates a pseudo device /dev/hwrandom which can be used as input device for rngd. The daemon supports reading from a local device or loads the random data from a RandPi entropy server (protocol version 2). If reading from the server the daemon decrypts the random data and checks the signature. You have to use the same secret and salt on the server and the client.
