 .Sh DESCRIPTION
-The
-.Fn arc4random
-function uses the key stream generator employed by the
-arc4 cipher, which uses 8*8 8 bit S-Boxes.
-The S-Boxes
-can be in about
-.if t 2\u\s71700\s10\d
-.if n (2**1700)
-states.
-The
-.Fn arc4random
-function returns pseudo-random numbers in the range of 0 to
-.if t 2\u\s731\s10\d\(mi1,
-.if n (2**32)\(mi1,
-and therefore has twice the range of
-.Xr rand 3
+.Pp
+These functions use a cryptographic pseudo-random number generator to generate
+high quality random bytes very quickly.  One data pool is used for all
+consumers in a process, so that consumption under program flow can act as
+additional stirring.  The subsystem is re-seeded from the kernel random number
+subsystem on a regular basis, and also upon 
+.Xr fork 2 .
+.Pp
+This family of functions provides higher quality random data than those
+described in
+.Xr rand 3 ,
+.Xr random 3 ,
 and
-.Xr random 3 .
+.Xr rand48 3 .
+They can be called in almost environments, including
+.Xr chroot 2
+and their use is encouraged over all other standard library functions for
+random numbers.
+.Pp
+.Fn arc4random
+returns a single 32-bit value.

 .Pp

 .Fa upper_bound .
-.Fn arc4random_uniform
-is recommended over constructions like
+This is recommended over constructions like
 .Dq Li arc4random() % upper_bound
 as it avoids "modulo bias" when the upper bound is not a power of two.
-.Pp
-The
-.Fn arc4random_stir
-function reads data from
-.Pa /dev/urandom
-and uses it to permute the S-Boxes via
-.Fn arc4random_addrandom .
-.Pp
-There is no need to call
-.Fn arc4random_stir
-before using
-.Fn arc4random
-functions family, since
-they automatically initialize themselves.
-.Sh EXAMPLES
-The following produces a drop-in replacement for the traditional
-.Fn rand
-and
-.Fn random
-functions using
-.Fn arc4random :
-.Pp
-.Dl "#define foo4random() (arc4random() % ((unsigned)RAND_MAX + 1))"
+In the worst case, this function may require multiple iterations
+to ensure uniformity.
+.Sh RETURN VALUES
+These functions are always successful, and no return value is
+reserved to indicate an error.

 .Sh HISTORY
-.Pa RC4
-has been designed by RSA Data Security, Inc.
-It was posted anonymously
-to the USENET and was confirmed to be equivalent by several sources who
-had access to the original cipher.
-Since
-.Pa RC4
-used to be a trade secret, the cipher is now referred to as
-.Pa ARC4 .
+The original version of this random number generator used the RC4 (also known
+as ARC4) algorithm.  In OS X 10.12 it was replaced with the NIST-approved AES
+cipher, and it may be replaced again in the future as cryptographic techniques
+advance.  A good mnemonic is
+.Dq A Replacement Call for Random .
