EVP_PKEY_new(3)              OpenSSL              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.
