|  | =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. | 
|  |  | 
|  | RSA_free() frees the B<RSA> structure and its components. The key is | 
|  | erased before the memory is returned to the system. | 
|  |  | 
|  | =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. |

|  | =head1 HISTORY | 
|  |  | 
|  | RSA_new() and RSA_free() are available in all versions of SSLeay and OpenSSL. |
