FIDO_DEV_MAKE_CRED(3)      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.
