Previous Comments: ------------------------------------------------------------------------ [2015-05-25 20:01:51] jdavis at outlook dot com Description: ------------ Using the crypt function, identical code will result in an output that will vary depending on the PHP version. Test script: --------------- <?php $salt = "KFtIFW1vulG5nUH3a0Mv"; $password = "testtest"; $key = '$2y$07$'; $key = $key.$salt."$"; echo crypt($password, $key); ?> Expected result: ---------------- I expect the result to be the same for every version, as this function can be used for login/passwords and updating PHP can result in an unusable login. Actual result: -------------- An example can be seen here: http://3v4l.org/qqHUe -Output for 5.3.7 - 5.4.41, 5.5.21 - 5.5.25, 5.6.5 - 5.6.9: $2y$07$KFtIFW1vulG5nUH3a0Mv$.0imhrNa/laTsN0Ioj5m357/a8AxxF2q -Output for 5.5.0 - 5.5.20, 5.6.0 - 5.6.4: $2y$07$KFtIFW1vulG5nUH3a0Mv$e0imhrNa/laTsN0Ioj5m357/a8AxxF2q ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69707&edit=1
