141 EVP_PKEY_new, EVP_PKEY_free \- private key allocation functions.
143 .IX Header "SYNOPSIS"
145 \& #include <openssl/evp.h>
147 \& EVP_PKEY *EVP_PKEY_new(void);
148 \& void EVP_PKEY_free(EVP_PKEY *key);
151 .IX Header "DESCRIPTION"
152 The \fIEVP_PKEY_new()\fR function allocates an empty \fB\s-1EVP_PKEY\s0\fR
153 structure which is used by OpenSSL to store private keys.
155 \&\fIEVP_PKEY_free()\fR frees up the private key \fBkey\fR.
158 The \fB\s-1EVP_PKEY\s0\fR structure is used by various OpenSSL functions
159 which require a general private key without reference to any
160 particular algorithm.
162 The structure returned by \fIEVP_PKEY_new()\fR is empty. To add a
163 private key to this empty structure the functions described in
164 \&\fIEVP_PKEY_set1_RSA\fR\|(3) should be used.
166 .IX Header "RETURN VALUES"
167 \&\fIEVP_PKEY_new()\fR returns either the newly allocated \fB\s-1EVP_PKEY\s0\fR
168 structure of \fB\s-1NULL\s0\fR if an error occurred.
170 \&\fIEVP_PKEY_free()\fR does not return a value.
