NAME

       shisa_key_update - API function

SYNOPSIS

       #include <shisa.h>

       int  shisa_key_update(Shisa  * dbh, const char * realm, const char * principal, const Shisa_key * oldkey,
       const Shisa_key * newkey);

ARGUMENTS

       Shisa * dbh Shisa library handle created by shisa().

       const char * realm
                   Name of realm the principal belongs in.

       const char * principal
                   Name of principal to remove key for.

       const Shisa_key * oldkey
                   Pointer to Shisa key structure with hints on matching the key to modify.

       const Shisa_key * newkey
                   Pointer to Shisa key structure with new values for the key, note that  all  fields  are  used
                   (and not just the ones specified by oldkey).

DESCRIPTION

       Modify  data  about  a  key  in  the database, for the given PRINCIPALREALM.  First the oldkey is used to
       locate the key to update (similar to shisa_keys_find()), then that key is modified  to  contain  whatever
       information  is  stored  in  newkey.  Not all elements of oldkey need to be filled out, only enough as to
       identify the key uniquely.  For example, if you want to modify the information stored for  the  only  key
       with an etype of 3 (DES-CBC-MD5), set the key->etype field to 3, and set all other fields to 0.

RETURN VALUE

       Returns  SHISA_OK on success, SHISA_NO_KEY if no key could be identified, and SHISA_MULTIPLE_KEY_MATCH if
       more than one key matched the given criteria, or an error code.
