Purpose: https://cgit.freebsd.org/ports/commit/multimedia/zoneminder/Makefile?id=7113c9db460962b726bd1fb61f9b087637aebd9f Upstream issue: https://github.com/ZoneMinder/zoneminder/issues/4333 I found only one place in "scripts/zmupdate.pl.in": > use Data::Entropy::Algorithms qw(rand_bits); > my $salt = Crypt::Eksblowfish::Bcrypt::en_base64(rand_bits(16*8)); I think it's easy to replace with another random generator. > For most purposes (including cryptography and security), > modules like Crypt::URandom, Crypt::SysRandom or Crypt::PRNG > are more than adequate.
