.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBEVP_PKEY_new()\fR function allocates an empty \fB\s-1EVP_PKEY\s0\fR 
structure which is used by OpenSSL to store private keys.
.PP
\&\fBEVP_PKEY_free()\fR frees up the private key \fBkey\fR.
.SH "NOTES"
.IX Header "NOTES"
The \fB\s-1EVP_PKEY\s0\fR structure is used by various OpenSSL functions
which require a general private key without reference to any
particular algorithm.
.PP
The structure returned by \fBEVP_PKEY_new()\fR is empty. To add a
private key to this empty structure the functions described in
\&\fBEVP_PKEY_set1_RSA\fR\|(3) should be used.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBEVP_PKEY_new()\fR returns either the newly allocated \fB\s-1EVP_PKEY\s0\fR
structure of \fB\s-1NULL\s0\fR if an error occurred.
.PP
\&\fBEVP_PKEY_free()\fR does not return a value.
