Dear community of the cplusplus.com forum!
We are pleased to share with you this C++ open source code published under the ISC license, that works as a high performance rearray binary tool.
Its purpose is to help test the strength of a source of entropy joining the first octet with the next first octet after 16, 32, 64, 128, 256 or 512 bits, the second octet with the next second octect, and so on.
After arraying all respective octets together, we recommend running an entropy estimation tool of each group of octets, in order to test the strength of a source of entropy.
For example, if your pseudorandom/truerandom numbers generator streams 16 bits after each cycle, then we recommend you to run
rearray-16 followed by estimations of entropy for each group and if you want, also statistical tests.
We hope it is helpful for at least some of you!
