NAME

       EVP_PKEY_new, EVP_PKEY_free - private key allocation functions.

SYNOPSIS

        #include <openssl/evp.h>

        EVP_PKEY *EVP_PKEY_new(void);
        void EVP_PKEY_free(EVP_PKEY *key);

DESCRIPTION

       The EVP_PKEY_new() function allocates an empty EVP_PKEY structure which
       is used by OpenSSL to store private keys.

       EVP_PKEY_free() frees up the private key key.

NOTES

       The EVP_PKEY structure is used by various OpenSSL functions which
       require a general private key without reference to any particular algo-
       rithm.

       The structure returned by EVP_PKEY_new() is empty. To add a private key
       to this empty structure the functions described in EVP_PKEY_set1_RSA(3)
       should be used.

RETURN VALUES

       EVP_PKEY_new() returns either the newly allocated EVP_PKEY structure of
       NULL if an error occurred.

       EVP_PKEY_free() does not return a value.
