=head1 SYNOPSIS
|
||
|
|
|
||
|
|
#include "internal/providercommon.h"
|
||
|
|
|
||
|
|
const char *ossl_prov_util_nid_to_name(int nid);
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The ossl_prov_util_nid_to_name() returns the name of an algorithm given a NID
|
||
|
|
in the B<nid> parameter. For the default and legacy providers it is equivalent
|
||
|
|
to calling OBJ_nid2sn(). The FIPS provider does not have the object database
|
||
|
|
code available to it (because that code relies on the ASN.1 code), so this
|
||
|
|
function is a static lookup of all known FIPS algorithm NIDs.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
Returns a pointer to the algorithm name, or NULL on error.
