</div>Ref. above, I'm still seeing these messages, indicating that<br>
either the Botan library didn't get the required bits from<br>
/dev/random or /dev/urandom (which should in itself be an<br>
inexhaustible source of pseudo-random bits), or this statement<br>
isn't quite correct for the version I'm using.<br>
<br>
My botan package is version 1.8.14 (which could possibly stand an<br>
update to at least something 1.10ish).<br></blockquote><div><br></div><div>I might see an issue in the Botan code. I will verify this with Jack, but the issue might be that it breaks out from the for-loop in the Device_EntropySource, even if the polling goal is not fulfilled. When reading from /dev/random, you might not get all bytes as you requested. When returning from the Device_EntropySource, the RNG will notice this and continue to the next entropy source type. Thus not even trying the /dev/urandom.</div>
