Thanks, Dieter.  I used /dev/urandom; don't know if that's sufficient for
my purposes.  

For the record, this is what I'm seeing.  How much entropy do I need?  

$ sudo rndctl -ls
Source                 Bits Type      Flags
wd1                    6180 disk estimate, collect
wd0                 1641540 disk estimate, collect
sip2                      0 net  
sip1                      0 net  
sip0                      0 net  
          1647730 bits mixed into pool
                0 bits currently stored in pool (max 4096)
          1601306 bits of entropy discarded due to full pool
            46424 hard-random bits generated
           334152 pseudo-random bits generated
