1. A method, comprising: identifying, by a processing device, a plurality of entropy sources; receiving random bits from each of the plurality of entropy sources; identifying a minimum number of bits among numbers of bits received from each of two or more entropy sources of the plurality of entropy sources; mixing, into an entropy pool, at least the identified minimum number of bits received from each entropy source of two or more entropy sources; and increasing a size of the entropy pool by the identified minimum number of bits.
