1632 tristate "Jitterentropy Non-Deterministic Random Number Generator"
1635 The Jitterentropy RNG is a noise that is intended
1636 to provide seed to another RNG. The RNG does not
1637 perform any cryptographic whitening of the generated
1638 random numbers. This Jitterentropy RNG registers with
1639 the kernel crypto API and can be used by any caller.
