XI. Crack Functions

소개

These functions allow you to use the CrackLib library to test the 'strength' of a password. The 'strength' of a password is tested by that checks length, use of upper and lower case and checked against the specified CrackLib dictionary. CrackLib will also give helpful diagnostic messages that will help 'strengthen' the password.

예제

This example shows how to open a CrackLib dictionary, test a given password, retrieve any diagnostic messages, and close the dictionary.
예 1. CrackLib example
<?php // Open CrackLib Dictionary $dictionary = crack_opendict('/usr/local/lib/pw_dict') or die('Unable to open CrackLib dictionary'); // Perform password check $check = crack_check($dictionary, 'gx9A2s0x'); // Retrieve messages $diag = crack_getlastmessage(); echo $diag; // 'strong password' // Close dictionary crack_closedict($dictionary); ?>

참고: If crack_check() returns TRUE, crack_getlastmessage() will return 'strong password'.

차례
crack_check -- Performs an obscure check with the given password
crack_closedict -- Closes an open CrackLib dictionary
crack_getlastmessage -- Returns the message from the last obscure check
crack_opendict -- Opens a new CrackLib dictionary
