Login by username/password may be dangerous in unencrypted network. Here i provide a small tool to login with encrypted password by the challenge/response mechanism. Changing the password is also possible in encrypted mode, so an eavesdropper gets no information from sniffing. The password may also be stored encrypted in the database table to prevent from hacking the sql server.
All is done by css/javascript on the client site (and some small helpers/libraries/controllers on the server). I provide a complete CI 2.x framework in the download file, so you may have to unpack the archive into your www folder, open then documentation file and start getting accustomed to the tool before introducing it into your application.
Please follow the download link and let me know, if you find some bugs or have additional ideas.
