=head1 NAME
|
|
|
|
RSA_new, RSA_free - allocate and free RSA objects
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/rsa.h>
|
|
|
|
RSA * RSA_new(void);
|
|
|
|
void RSA_free(RSA *rsa);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
RSA_new() allocates and initializes an B<RSA> structure. It is equivalent to
|
|
calling RSA_new_method(NULL).
|
|
|
|
RSA_free() frees the B<RSA> structure and its components. The key is
|
|
erased before the memory is returned to the system.
|
|
If B<rsa> is NULL nothing is done.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
If the allocation fails, RSA_new() returns B<NULL> and sets an error
|
|
code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns
|
|
a pointer to the newly allocated structure.
|
|
|
|
RSA_free() returns no value.
