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 algorithm.

       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.
