Currently, there are two different directories which contain internal header files of libcrypto which are meant to be shared internally: While header files in 'include/internal' are intended to be shared between libcrypto and libssl, the files in 'crypto/include/internal' are intended to be shared inside libcrypto only. To make things complicated, the include search path is set up in such a way that the directive #include "internal/file.h" could refer to a file in either of these two directoroes. This makes it necessary in some cases to add a '_int.h' suffix to some files to resolve this ambiguity: #include "internal/file.h" # located in 'include/internal' #include "internal/file_int.h" # located in 'crypto/include/internal' This commit moves the private crypto headers from 'crypto/include/internal' to 'include/crypto' As a result, the include directives become unambiguous #include "internal/file.h" # located in 'include/internal' #include "crypto/file.h" # located in 'include/crypto' hence the superfluous '_int.h' suffixes can be stripped. The files 'store_int.h' and 'store.h' need to be treated specially; they are joined into a single file.

=head1 NAME
|
|
|
|
evp_keymgmt_export_to_provider,
|
|
evp_keymgmt_clear_pkey_cache
|
|
- key material provider export for EVP
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include "crypto/evp.h"
|
|
|
|
void *evp_keymgmt_export_to_provider(EVP_PKEY *pk, EVP_KEYMGMT *keymgmt);
|
|
void evp_keymgmt_clear_pkey_cache(EVP_PKEY *pk);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
evp_keymgmt_export_to_provider() exports the key material from the
|
|
given key I<pk> to a provider via a B<EVP_KEYMGMT> interface, if this
|
|
hasn't already been done.
|
|
It maintains a cache of provider key references in I<pk> to keep track
|
|
of all such exports.
|
|
|
|
If I<pk> has an assigned legacy key, a check is done to see if any of
|
|
its key material has changed since last export, i.e. the legacy key's
|
|
is_dirty() method returns 1.
|
|
If it has, the cache of already exported keys is cleared, and a new
|
|
export is made with the new key material.
|
|
|
|
evp_keymgmt_clear_pkey_cache() can be used to explicitly clear the
|
|
cache of provider key references.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
evp_keymgmt_export_to_provider() returns a pointer to the appropriate
|
|
provider side key (created or found again), or NULL on error.
|
|
|
|
=head1 NOTES
|
|
|
|
"Legacy key" is the term used for any key that has been assigned to an
|
|
B<EVP_PKEY> with EVP_PKEY_assign_RSA() and similar functions.
