131 .IX Title "EVP_PKEY_new 3"
132 .TH EVP_PKEY_new 3 "2008-09-27" "0.9.8i" "OpenSSL"
134 EVP_PKEY_new, EVP_PKEY_free \- private key allocation functions.
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/evp.h>
142 \& EVP_PKEY *EVP_PKEY_new(void);
143 \& void EVP_PKEY_free(EVP_PKEY *key);
146 .IX Header "DESCRIPTION"
147 The \fIEVP_PKEY_new()\fR function allocates an empty \fB\s-1EVP_PKEY\s0\fR
148 structure which is used by OpenSSL to store private keys.
150 \&\fIEVP_PKEY_free()\fR frees up the private key \fBkey\fR.
153 The \fB\s-1EVP_PKEY\s0\fR structure is used by various OpenSSL functions
154 which require a general private key without reference to any
155 particular algorithm.
157 The structure returned by \fIEVP_PKEY_new()\fR is empty. To add a
158 private key to this empty structure the functions described in
159 \&\fIEVP_PKEY_set1_RSA\fR\|(3) should be used.
161 .IX Header "RETURN VALUES"
162 \&\fIEVP_PKEY_new()\fR returns either the newly allocated \fB\s-1EVP_PKEY\s0\fR
163 structure of \fB\s-1NULL\s0\fR if an error occurred.
165 \&\fIEVP_PKEY_free()\fR does not return a value.
