Bug description:crypt() function incorrectly falls back to CRYPT_STD_DES
Description:
------------
The crypt() method fails bcrypt test vectors given by Openwall's crypt
v1.2.
Specifically, when given an invalid identifier, crypt() falls back to
CRYPT_STD_DES, even though the first two bytes of the salt do not match the
documented "./0-9A-Za-z" range for CRYPT_STD_DES. The expected behavior
would be
to return *0.
I've tested this under PHP 5.3.10 on Zend Server on CentOS 5 and Windows 7.
Test script:
---------------
<?php
// Expect *0, returns $2OahnOya9Dwg
echo crypt('', '$2`$05$CCCCCCCCCCCCCCCCCCCCC.') . PHP_EOL;
// Expect *0, returns $2OahnOya9Dwg
echo crypt('', '$2{$05$CCCCCCCCCCCCCCCCCCCCC.') . PHP_EOL;
// Expect *1, returns *0Vh7kctua2ww
echo crypt('', '*0') . PHP_EOL;
Expected result:
----------------
*0
*0
*1
Actual result:
--------------
$2OahnOya9Dwg
$2OahnOya9Dwg
*0Vh7kctua2ww
