++.Dt ARC4RANDOM 3
++.Os
++.Sh NAME
++.Nm arc4random ,
++.Nm arc4random_stir ,
++.Nm arc4random_addrandom
++.Nd arc4 random number generator
++.Sh SYNOPSIS
++.Fd #include <stdlib.h>
++.Ft uint32_t
++.Fn arc4random "void"
++.Ft void
++.Fn arc4random_stir "void"
++.Ft void
++.Fn arc4random_addrandom "u_char *dat" "int datlen"
++.Sh DESCRIPTION
++The
++.Fn arc4random
++function provides a high quality 32-bit pseudo-random
++number very quickly.
++.Fn arc4random
++seeds itself on a regular basis from the kernel strong random number
++subsystem described in
++.Xr random 4 .
++On each call, an ARC4 generator is used to generate a new result.
++The
++.Fn arc4random
++function uses the ARC4 cipher key stream generator,
++which uses 8*8 8-bit S-Boxes.
++The S-Boxes can be in about (2**1700) states.
++.Pp
++.Fn arc4random
++fits into a middle ground not covered by other subsystems such as
++the strong, slow, and resource expensive random
++devices described in
++.Xr random 4
++versus the fast but poor quality interfaces described in
++.Xr rand 3 ,
++.Xr random 3 ,
++and
++.Xr drand48 3 .
++.Pp
++The
++.Fn arc4random_stir
++function reads data from a pseudo-random device, usually
++.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 ,
++since
++.Fn arc4random
++automatically initializes itself.
++.Sh SEE ALSO
++.Xr rand 3 ,
++.Xr rand48 3 ,
++.Xr random 3
++.Sh HISTORY
++An algorithm called
++.Pa RC4
++was designed by RSA Data Security, Inc.
++It was considered a trade secret.
++Because it was a trade secret, it obviously could not be patented.
++A clone of this was posted anonymously to USENET and confirmed to
++be equivalent by several sources who had access to the original cipher.
++Because of the trade secret situation, RSA Data Security, Inc. can do
++nothing about the release of the ARC4 algorithm.
++Since
++.Pa RC4
++used to be a trade secret, the cipher is now referred to as
++.Pa ARC4 .
++.Pp
++These functions first appeared in
++.Ox 2.1 .
