I would feel more comfortable when using other measures like SP800-90B which even provides a tool for the analysis. I understand that entropy estimates, well, are estimates. But the ent data is commonly not very conservative. [1] https://github.com/usnistgov/SP800-90B_EntropyAssessment Ciao Stephan
