Siphash-2-4 is now our hash in nearly all cases. I've made an exception for cases where I'm sure that users can't influence the inputs. This is likely to cause a slowdown somewhere, but it's safer to siphash everything and then look for cases to optimize. This patch doesn't actually get us any _benefit_ from siphash yet, since we don't really randomize the key at any point. 2014-02-07 17:38:16 -05:00

On shutdown, mark openssl as uninitialized. This causes openssl to get completely reinitialized on startup, which is probably a good idea. 2018-01-11 12:49:28 -05:00			`void siphash_unset_global_key(void);`
