PHP Bug Type: *Encryption and hash functions
Bug description: crypt ignores sha512 prefix
Description:
------------
PHP has the crypt()-function which can create salted-hashes (e.g. usable
for shadow-passwords). Although it's not documented, in PHP 5.2 it was
possible to pass the prefix for sha512 like in the corresponding
glibc-function.
Example:
echo crypt('foo','$6$$bar$');
gives
$6$$QMXjqd7rHQZPQ1yHsXkQqC1FBzDiVfTHXL.LaeDAeVV.IzMaV9VU4MQ8kPuZa2SOP1A0RPm772EaFYjpEJtdu.
Now the same code in PHP 5.3.1 gives
$6A86JNndVTdM
(which is basically just crypt ignoring the $6-prefix for the salt)
I assume may have something to do with (cited from crypt-documentation):
"Note: As of PHP 5.3.0, PHP contains its own implementation and will use
that if the system lacks of support for one or more of the algorithms. "
Reproduce code:
---------------
echo crypt('foo','$6$$bar$');
Expected result:
----------------
$6$$QMXjqd7rHQZPQ1yHsXkQqC1FBzDiVfTHXL.LaeDAeVV.IzMaV9VU4MQ8kPuZa2SOP1A0RPm772EaFYjpEJtdu.
Actual result:
--------------
$6A86JNndVTdM
