DESCRIPTION¶

The fido_credman_metadata_t type abstracts credential management metadata.

The fido_credman_metadata_new() function returns a pointer to a newly allocated, empty fido_credman_metadata_t type. If memory cannot be allocated, NULL is returned.

The fido_credman_metadata_free() function releases the memory backing *metadata_p, where *metadata_p must have been previously allocated by fido_credman_metadata_new(). On return, *metadata_p is set to NULL. Either metadata_p or *metadata_p may be NULL, in which case fido_credman_metadata_free() is a NOP.

The fido_credman_get_dev_metadata() function populates metadata with information retrieved from dev. A valid pin must be provided.

The fido_credman_rk_existing() function inspects metadata and returns the number of resident credentials on the authenticator. The fido_credman_rk_remaining() function inspects metadata and returns the estimated number of resident credentials that can be created on the authenticator.

The fido_credman_rk_t type abstracts the set of resident credentials belonging to a given relying party.

The fido_credman_rk_new() function returns a pointer to a newly allocated, empty fido_credman_rk_t type. If memory cannot be allocated, NULL is returned.

The fido_credman_rk_free() function releases the memory backing *rk_p, where *rk_p must have been previously allocated by fido_credman_rk_new(). On return, *rk_p is set to NULL. Either rk_p or *rk_p may be NULL, in which case fido_credman_rk_free() is a NOP.

The fido_credman_get_dev_rk() function populates rk with the set of resident credentials belonging to rp_id in dev. A valid pin must be provided.

The fido_credman_rk_count() function returns the number of resident credentials in rk. The fido_credman_rk() function returns a pointer to the credential at index idx in rk. Please note that the first credential in rk has an idx (index) value of 0.

The fido_credman_del_dev_rk() function deletes the resident credential identified by cred_id from dev, where cred_id points to cred_id_len bytes. A valid pin must be provided.

The fido_credman_rp_t type abstracts information about a relying party.

The fido_credman_rp_new() function returns a pointer to a newly allocated, empty fido_credman_rp_t type. If memory cannot be allocated, NULL is returned.

The fido_credman_rp_free() function releases the memory backing *rp_p, where *rp_p must have been previously allocated by fido_credman_rp_new(). On return, *rp_p is set to NULL. Either rp_p or *rp_p may be NULL, in which case fido_credman_rp_free() is a NOP.

The fido_credman_get_dev_rp() function populates rp with information about relying parties with resident credentials in dev. A valid pin must be provided.

The fido_credman_rp_count() function returns the number of relying parties in rp.

The fido_credman_rp_id() and fido_credman_rp_name() functions return pointers to the id and name of relying party idx in rp. If not NULL, the values returned by these functions point to NUL-terminated UTF-8 strings. Please note that the first relying party in rp has an idx (index) value of 0.

The fido_credman_rp_id_hash_ptr() function returns a pointer to the hashed id of relying party idx in rp. The corresponding length can be obtained by fido_credman_rp_id_hash_len(). Please note that the first relying party in rp has an idx (index) value of 0.
