- changed random generator from random(3) clone to arc4random wrapped
|
||||
for thread safety. The random generator is initialised with
|
||||
entropy from the system.
|
||||
- fix crash where failure to prime DNSKEY tried to print null pointer
|
||||
in the log message.
|
||||
|

16 October 2007: Wouter
|
