Customers migration: old passwords

[em.pe]

Hello,

I have about 100 customers in Zencart. After import, login by customers is not possible. I found a problem:

In Zencart - saving password looks like:

$salt = substr(md5($password), 0, 2);
$password = md5($salt . $password) . ':' . $salt;
(e.g. b3fc93970326ba7dcda25ea193017f90:72)

In Prestashop:

md5(_COOKIE_KEY_.$passwd)

1. Can I convert old passwords to new string (acceptable by Presta)? Is it possible?
2. If not, what is a solution? I have two ideas:
a) Edit files in Presta (adjust decrypt to Zencart method). (?)
Edit files, but: if ID's are from, e.g. 1 to 100 - use old (Zencart) method, for others ID's - use new method from Presta. (?)


Thanks in advance.

Tomer and I encountered this problem in the osCommerce to PrestaShop Import module we wrote. We found it impossible to convert osCommerce passwords into PrestaShop passwords. The solution we came up with was to modify the Customer class to accept both osCommerce and PrestaShop passwords.

Thank you very much for quickly answer. So, you an Tomer modify only "classes/Customer.php" file?

Yes, but since it is a paid module, I cannot give you the code.
