-=head1 NAME
-
-RAND_set_rand_method, RAND_get_rand_method, RAND_SSLeay - select RAND method
-
-=head1 SYNOPSIS
-
- #include <openssl/rand.h>
-
- void RAND_set_rand_method(RAND_METHOD *meth);
-
- RAND_METHOD *RAND_get_rand_method(void);
-
- RAND_METHOD *RAND_SSLeay(void);
-
-=head1 DESCRIPTION
-
-A B<RAND_METHOD> specifies the functions that OpenSSL uses for random
-number generation. By modifying the method, alternative
-implementations such as hardware RNGs may be used. Initially, the
-default is to use the OpenSSL internal implementation. RAND_SSLeay()
-returns a pointer to that method.
-
-RAND_set_rand_method() sets the RAND method to B<meth>.
-RAND_get_rand_method() returns a pointer to the current method.
-
-=head1 THE RAND_METHOD STRUCTURE
-
- typedef struct rand_meth_st
- {
- void (*seed)(const void *buf, int num);
- int (*bytes)(unsigned char *buf, int num);
- void (*cleanup)(void);
- void (*add)(const void *buf, int num, int entropy);
- int (*pseudorand)(unsigned char *buf, int num);
- int (*status)(void);
- } RAND_METHOD;
-
-The components point to the implementation of RAND_seed(),
-RAND_bytes(), RAND_cleanup(), RAND_add(), RAND_pseudo_rand()
-and RAND_status().
-Each component may be NULL if the function is not implemented.
-
-=head1 RETURN VALUES
-
-RAND_set_rand_method() returns no value. RAND_get_rand_method() and
-RAND_SSLeay() return pointers to the respective methods.
-
-=head1 SEE ALSO
-
-L<rand(3)|rand(3)>
-
-=head1 HISTORY
-
-RAND_set_rand_method(), RAND_get_rand_method() and RAND_SSLeay() are
-available in all versions of OpenSSL.
