Even more randomness

Contributed by rueda on from the and-how-would-sir-like-his-randomness? dept.

Damien Miller (djm@) 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.
