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. | |
