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