=head1 NAME
|
|
|
|
EVP_PKEY_get_group_name - get private key group name
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/evp.h>
|
|
|
|
int EVP_PKEY_get_group_name(EVP_PKEY *pkey, char *gname, size_t gname_sz,
|
|
size_t *gname_len);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
EVP_PKEY_get_group_name() fills in the group name of the I<pkey> into
|
|
I<gname>, up to at most I<gname_sz> bytes including the ending NUL byte
|
|
and assigns I<*gname_len> the actual size of the name, if I<pkey>'s key type
|
|
supports it.
|
|
I<gname> as well as I<gname_len> may individually be NULL, and won't be
|
|
filled in or assigned in that case.
|
|
|
|
=head1 NOTES
|
|
|
|
Among the standard OpenSSL key types, this is only supported for DH, EC and
|
|
SM2 keys. Other providers may support this for additional key types.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
EVP_PKEY_get_group_name() returns 1 if the group name could be filled in,
|
|
otherwise 0.
