| auth_setup() X-Ref |
| Initialize the auth system. This function is automatically called at the end of init.php This used to be the main() of the auth.php triggers: AUTH_LOGIN_CHECK return: bool |
| auth_loadACL() X-Ref |
| Loads the ACL setup and handle user wildcards author: Andreas Gohr <andi@splitbrain.org> return: array |
| auth_login_wrapper($evdata) X-Ref |
| Event hook callback for AUTH_LOGIN_CHECK param: array $evdata return: bool |
| auth_login($user, $pass, $sticky = false, $silent = false) X-Ref |
| This tries to login the user based on the sent auth credentials The authentication works like this: if a username was given a new login is assumed and user/password are checked. If they are correct the password is encrypted with blowfish and stored together with the username in a cookie - the same info is stored in the session, too. Additonally a browserID is stored in the session. If no username was given the cookie is checked: if the username, crypted password and browserID match between session and cookie no further testing is done and the user is accepted If a cookie was found but no session info was availabe the blowfish encrypted password from the cookie is decrypted and together with username rechecked by calling this function again. On a successful login $_SERVER[REMOTE_USER] and $USERINFO are set. author: Andreas Gohr <andi@splitbrain.org> param: string $user Username param: string $pass Cleartext Password param: bool $sticky Cookie should not expire param: bool $silent Don't show error on bad auth return: bool true on successful auth |
| auth_browseruid() X-Ref |
| Builds a pseudo UID from browser and IP data This is neither unique nor unfakable - still it adds some security. Using the first part of the IP makes sure proxy farms like AOLs are still okay. author: Andreas Gohr <andi@splitbrain.org> return: string a SHA256 sum of various browser headers |
| auth_cookiesalt($addsession = false, $secure = false) X-Ref |
| Creates a random key to encrypt the password in cookies This function tries to read the password for encrypting cookies from $conf['metadir'].'/_htcookiesalt' if no such file is found a random key is created and and stored in this file. author: Andreas Gohr <andi@splitbrain.org> param: bool $addsession if true, the sessionid is added to the salt param: bool $secure if security is more important than keeping the old value return: string |

| auth_decrypt($ciphertext, $secret) X-Ref |
| Decrypt the given AES ciphertext The mode is CBC, the key is derived using pbkdf2 param: string $ciphertext The encrypted data param: string $secret The secret/password that shall be used return: string The decrypted data |
| auth_logoff($keepbc = false) X-Ref |

| auth_ismanager($user = null, $groups = null, $adminonly = false, $recache=false) X-Ref |
