Description Ratul Gupta 2013-10-17 11:05:22 UTC

Pwgen was found to silently falling back to use standard pseudo generated numbers on the systems that heavily use entropy.

Systems, such as those with a lot of daemons providing encryption services, the entropy was found to be exhausted, which forces pwgen to fall back to use standard pseudo generated numbers.

There seems to be a patch here saying it fixes most of the issues:
