Here is the way that passwords are stored in the customers table in Konakart (and oscommerce):

The hex string before the ':' is the md5 hash of the plain text password pre-pended by the two random characters after the colon.
So if the plain text password is 'password' (without the quotes), you should run '8fpassword' through your md5 hash generator. It will return:
bb2c19e53d9603b7750ab18edb8f632b
