=head1 NAME

EVP_PKEY_new, EVP_PKEY_free - private key allocation functions.

=head1 SYNOPSIS

 #include <openssl/evp.h>

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


=head1 DESCRIPTION

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

EVP_PKEY_free() frees up the private key B<key>.

=head1 NOTES

The B<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
L<EVP_PKEY_set1_RSA(3)|EVP_PKEY_set1_RSA(3)> should be used.

=head1 RETURN VALUES

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

EVP_PKEY_free() does not return a value.
