Empty devices ar

/Dev/random and/dev/urandom are Random Pseudo devices provided in Linux. The tasks of these two devices are to provide random byte data streams that are never empty. Many decryption and security applications (such as SSH keys and SSL keys) require random data streams they provide.
The difference between the two devices is that the/
/dev, device file storage directory, the application through the read and write to these files and control, can access the actual equipment;
/sys/devices directory, according to the type of bus attached to the device, organized into a hierarchical structure, saving all the equipment of the system, is the file system management equipment, the most important directory structure;
This is the directory structure that the kernel devices are layered by

Random numbers in Linux can be generated from two special files, one/dev/urandom. The other is/dev/random. The principle of generating random numbers is to use the current system's entropy pool to calculate a fixed number of random bits, and then return these bits as a byte stream. Entropy pool is the current system of environmental noise, entropy refers to a system of chaos, system noise can be evaluated t
