methods

MsgField* RandomGenerator::RandomBytes(Size count)

Generate random bytes. Generates count bytes of random data and returns it in a MsgField. Used to generate data for padding size of messages and also for generating symetric and asymetric keys.

Returns:

MsgField filled with number random bytes

Parameters:

count - Number of bytes to generate

RandomGenerator::RandomGenerator(LogFile *aLogFile)

Random generator constructor. It opens device /dev/random and initializes its seed using the random data from it. /dev/random should provide us with suitable strength in randomness - if evene stronger randomness is required or bigger indenpendence on platform, we can modify this class to cooperate with some hardware random generator.

Parameters:

aLogFile - Log file for debug messages.
