BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504 The BaseRngLibTimerLib allows to generate number based on a timer. This mechanism allows to have a basic non-secure implementation for non-production platforms. To bind and identify Random Number Generators implementations with a GUID, an unsafe GUID should be added. This GUID cannot be added to the MdePkg unless it is also added to a specification. To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to the MdeModulePkg. This will allow to define an unsafe Rng GUID in a later patch in the MdeModulePkg. The MdePkg implementation will be removed later. This allows to give some time to platform owners to switch to the MdeModulePkg implementation.

# Instance of RNG (Random Number Generator) Library.
|
|
#
|
|
# BaseRng Library that uses the TimerLib to provide reasonably random numbers.
|
|
# Do NOT use this on a production system as this uses the system performance
|
|
# counter rather than a true source of random in addition to having a weak
|
|
# random algorithm. This is provided primarily as a source of entropy for
|
|
# OpenSSL for platforms that do not have a good built in RngLib as this
|
|
# emulates what was done before (though it isn't perfect).
