FIDO_DEV_MAKE_CRED(3) FreeBSD Library Functions Manual FIDO_DEV_MAKE_CRED(3)
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.
RETURN VALUES
The error codes returned by fido_dev_make_cred() are defined in
<fido/err.h>. On success, FIDO_OK is returned.
