158 structure which is used by OpenSSL to store private keys.

160 \&\fIEVP_PKEY_free()\fR frees up the private key \fBkey\fR.
161 .SH "NOTES"
162 .IX Header "NOTES"
163 The \fB\s-1EVP_PKEY\s0\fR structure is used by various OpenSSL functions
164 which require a general private key without reference to any
165 particular algorithm.
166 .PP
167 The structure returned by \fIEVP_PKEY_new()\fR is empty. To add a
168 private key to this empty structure the functions described in
169 \&\fIEVP_PKEY_set1_RSA\fR\|(3) should be used.
170 .SH "RETURN VALUES"
171 .IX Header "RETURN VALUES"
172 \&\fIEVP_PKEY_new()\fR returns either the newly allocated \fB\s-1EVP_PKEY\s0\fR
173 structure of \fB\s-1NULL\s0\fR if an error occurred.
