<P>
The <CODE>EVP_PKEY_new()</CODE> function allocates an empty <STRONG>EVP_PKEY</STRONG> 
structure which is used by OpenSSL to store private keys.

</P>
<P>
<CODE>EVP_PKEY_free()</CODE> frees up the private key <STRONG>key</STRONG>.

<H1><A NAME="NOTES">NOTES</A></H1>
<P>
The <STRONG>EVP_PKEY</STRONG> structure is used by various OpenSSL functions which require a general
private key without reference to any particular algorithm.

</P>
<P>
The structure returned by <CODE>EVP_PKEY_new()</CODE> is empty. To add a
private key to this empty structure the functions described in
<A HREF="../crypto/EVP_PKEY_set1_RSA.html#">EVP_PKEY_set1_RSA(3)</A> should be used.

<P>
<CODE>EVP_PKEY_new()</CODE> returns either the newly allocated <STRONG>EVP_PKEY</STRONG>
structure of <STRONG>NULL</STRONG> if an error occurred.

<P>
<CODE>EVP_PKEY_free()</CODE> does not return a value.
