EVP_PKEY_new(3)

     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.
