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.
