=head1 NAME
|
|
|
|
evp_pkey_make_provided - internal EVP_PKEY support functions for providers
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
/* Only for EVP source */
|
|
#include "evp_local.h"
|
|
|
|
void *evp_pkey_make_provided(EVP_PKEY *pk, OPENSSL_CTX *libctx,
|
|
EVP_KEYMGMT **keymgmt, const char *propquery,
|
|
int domainparams);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
evp_pkey_make_provided() ensures that the B<EVP_PKEY> I<pk> is provided within
|
|
the library context I<libctx> (NULL means the default context). I<keymgmt>
|
|
may point at a reference to a B<EVP_KEYMGMT>, and works as an input/output
|
|
parameter.
|
|
As input to this function, it can be used to specify a B<EVP_KEYMGMT> to be
|
|
used for exporting. If not (I<*keymgmt> is NULL), then this function will
|
|
fetch an B<EVP_KEYMGMT> implicitly, using I<propquery> as property query string.
|
|
As output from this function, I<*keymgmt> will be assigned the B<EVP_KEYMGMT>
|
|
that was used, if the export was successful, otherwise it will be assigned NULL.
|
|
I<domainparams> decides if I<pk> should be considered domain parameters or the
|
|
actual key.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
evp_pkey_make_provided() returns the provider key data that was exported if
|
|
I<pk> was successfully provided. Otherwise, NULL is returned.
|
|
|
|
=head1 NOTES
|
|
|
|
Some functions calling evp_pkey_make_provided() may have received a const
|
|
key, and may therefore have to cast the key to non-const form to call this
|
|
function. Since B<EVP_PKEY> is always dynamically allocated, this is OK.
