NAME

fido_dev_make_cred — generates a new credential on a FIDO2 device

SYNOPSIS

#include <fido.h>

int

fido_dev_make_cred ( fido_dev_t *dev , fido_cred_t *cred , const char *pin );

DESCRIPTION

The fido_dev_make_cred () function asks the FIDO2 device represented by dev to generate a new credential according to the following parameters defined in cred :

-

type ;

-

client data hash ;

-

relying party ;

-

user attributes ;

-

list of excluded credential IDs ;

-

resident/discoverable key and user verification attributes .

See fido_cred_set_authdata (3) for information on how these values are set.

If a PIN is not needed to authenticate the request against dev , then pin may be NULL. Otherwise pin must point to a NUL-terminated UTF-8 string.

After a successful call to fido_dev_make_cred (), the fido_cred_authdata_ptr (3), fido_cred_pubkey_ptr (3), fido_cred_x5c_ptr (3), and fido_cred_sig_ptr (3) functions may be invoked on cred to retrieve the various parts of the generated credential.

Please note that fido_dev_make_cred () is synchronous and will block if necessary.
