committed a change
randomising the rekeying interval in
arc4random(3)
(and friends):

CVSROOT:	/cvs
Module name:	src
Changes by:	djm@cvs.openbsd.org	2022/07/30 23:10:36

Modified files:
	lib/libc/crypt : arc4random.c 

Log message:
Randomise the rekey interval a little. Previously, the chacha20
instance would be rekeyed every 1.6MB. This makes it happen at a
random point somewhere in the 1-2MB range.
