=head1 NAME
|
|
|
|
EVP_PKEY_new, EVP_PKEY_up_ref, EVP_PKEY_free - private key allocation functions
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/evp.h>
|
|
|
|
EVP_PKEY *EVP_PKEY_new(void);
|
|
int EVP_PKEY_up_ref(EVP_PKEY *key);
|
|
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. The reference count is set to B<1>.
|
|
|
|
EVP_PKEY_up_ref() increments the reference count of B<key>.
|
|
|
|
EVP_PKEY_free() decrements the reference count of B<key> and, if the reference
|
|
count is zero, frees it up. If B<key> is NULL, nothing is done.
|
|
|
|
=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)> should be
|
|
used.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
EVP_PKEY_new() returns either the newly allocated B<EVP_PKEY> structure or
|
|
B<NULL> if an error occurred.
|
|
|
|
EVP_PKEY_up_ref() returns 1 for success and 0 for failure.

|
|
|
=head1 HISTORY
|
|
|
|
EVP_PKEY_new() and EVP_PKEY_free() exist in all versions of OpenSSL.
|
|
|
|
EVP_PKEY_up_ref() was first added to OpenSSL 1.1.0.
