The world needs more entropy!


The ChaosKey is a fully libre & open design, hardware random number generator for use with computers that have an available USB port.

The design provides bits at the maximum rate supported by full-speed USB, which is approximately 1 megabyte per second.

For Linux systems running kernel version 4.1 or newer, operation is as simple as plugging in the device, as a suitable driver for feeding random bits into the kernel entropy pool is already present in the kernel, and ChaosKey will automatically be detected and bound to this driver.
