fido_dev_make_cred - Man Page

generates a new credential on a FIDO2 device


#include <fido.h>

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


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:

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.
