getting diff results of crypt( ) ?

[Anon]

Hello !
I am using the following code to encrypt my password field . (DES 2 char salt is being used).
$salt=substr($pass,0,4);
$seem=crypt($pass,$salt);
Here encryted values will remain same for the same values of passwords.

In the following code i didnot mention the salt , so here crypt function use by default DES encryption with 2 char salt
$seem=crypt($pass);
But here encryted value will be generated randomly even for the same passwords.

In the above two examples , DES with 2 char salt is used but i am getting the different results in both cases . The result should be the same because in both cases DES 2 char salt encryption is being used.

Any suggestion
Regards

Your commentary says '2 char salt' in several places, but your code says:

$salt=substr($pass,0,4);

Looks like 4 chars to me...

sorry it was mistake
$salt=substr($pass,0,2);
