EVP_PKEY_GET_GROUP_NAME(3ossl) OpenSSL EVP_PKEY_GET_GROUP_NAME(3ossl)
NAME
EVP_PKEY_get_group_name - get group name of a key
SYNOPSIS
#include <openssl/evp.h>
int EVP_PKEY_get_group_name(EVP_PKEY *pkey, char *gname, size_t gname_sz,
size_t *gname_len);
DESCRIPTION
EVP_PKEY_get_group_name() fills in the group name of the pkey into
gname, up to at most gname_sz bytes including the ending NUL byte and
assigns *gname_len the actual length of the name not including the NUL
byte, if pkey's key type supports it. gname as well as gname_len may
individually be NULL, and won't be filled in or assigned in that case.
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.
RETURN VALUES
EVP_PKEY_get_group_name() returns 1 if the group name could be filled
in, otherwise 0.

This function was added in OpenSSL 3.0.
