* [rng] Add ANS X9.82 Approved Source of Entropy InputMichael Brown2012-02-211-13/+115
| | | | | | | | | | | | | | | | ANS X9.82 specifies several Approved Sources of Entropy Input (SEI). One such SEI uses an entropy source as the Source of Entropy Input, condensing each entropy source output after each GetEntropy call. This can be implemented relatively cheaply in iPXE and avoids the need to allocate potentially very large buffers. (Note that the terms "entropy source" and "Source of Entropy Input" are not synonyms within the context of ANS X9.82.) Use the iPXE API mechanism to allow entropy sources to be selected at compilation time. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [rng] Add dummy entropy sourceMichael Brown2012-01-231-0/+48
Cryptographic random number generation requires an entropy source, which is used as the input to a Deterministic Random Bit Generator (DRBG). iPXE does not currently have a suitable entropy source. Provide a dummy source to allow the DRBG code to be implemented. Signed-off-by: Michael Brown <mcb30@ipxe.org>
