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