　晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 sh-3ll

<p>RSA_new, RSA_free - allocate and free RSA objects</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/rsa.h&gt;

 RSA *RSA_new(void);

 void RSA_free(RSA *rsa);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>RSA_new() allocates and initializes an <b>RSA</b> structure. It is equivalent to calling RSA_new_method(NULL).</p>

<p>RSA_free() frees the <b>RSA</b> structure and its components. The key is erased before the memory is returned to the system. If <b>rsa</b> is NULL nothing is done.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>If the allocation fails, RSA_new() returns <b>NULL</b> and sets an error code that can be obtained by <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a>. Otherwise it returns a pointer to the newly allocated structure.</p>

<p>RSA_free() returns no value.</p>
