NAME

6       EVP_PKEY_get_group_name - get group name of a key
7

SYNOPSIS

9        #include <openssl/evp.h>
10
11        int EVP_PKEY_get_group_name(EVP_PKEY *pkey, char *gname, size_t gname_sz,
12                                    size_t *gname_len);
13

DESCRIPTION

15       EVP_PKEY_get_group_name() fills in the group name of the pkey into
16       gname, up to at most gname_sz bytes including the ending NUL byte and
17       assigns *gname_len the actual length of the name not including the NUL
18       byte, if pkey's key type supports it.  gname as well as gname_len may
19       individually be NULL, and won't be filled in or assigned in that case.

NOTES

22       Among the standard OpenSSL key types, this is only supported for DH, EC
23       and SM2 keys.  Other providers may support this for additional key
24       types.
25

RETURN VALUES

27       EVP_PKEY_get_group_name() returns 1 if the group name could be filled
28       in, otherwise 0.
