Available Packages
Name : RdRand
Version : 2.1.2
Release : 2.el8
Architecture : x86_64
Size : 43 k
Source : RdRand-2.1.2-2.el8.src.rpm
Repository : epel
Summary : Library for generating random numbers using the RdRand instruction on Intel CPUs
URL : https://github.com/jirka-h/RdRand
License : LGPLv2+
Description : RdRand is an instruction for returning random numbers from an Intel on-chip
: hardware random number generator.RdRand is available in Ivy Bridge and later
: processors.
:
: It uses cascade construction, combining a HW RNG operating at 3Gbps with CSPRNG
: with all components sealed on CPU. The entropy source is a meta-stable circuit,
: with unpredictable behavior based on thermal noise. The entropy is fed into
: a 3:1 compression ratio entropy extractor (whitener) based on AES-CBC-MAC.
: Online statistical tests are performed at this stage and only high quality
: random data are used as the seed for cryptograhically secure SP800-90 AES-CTR
: DRBG compliant PRNG.
: This generator is producing maximum of 512 128-bit AES blocks before it's
: reseeded. According to documentation the 512 blocks is a upper limit for
: reseed, in practice it reseeds much more frequently.
