Internet Sales Customer Password Encryption

We're running Internet Sales 5.0 which is connected to SAP ECC 6.0. We're in the process of outsourcing our B2c website and would like to export a customer list (the easy part) with passwords. The passwords are obviously encrypted so we've got a couple of questions, is there anywhere (table) the passwords are store unencrypted? If not, is there a way to decrypt them.

We're currently looking in table BAPIUSW01 which gives us the Internet Sales User Number and a column named Hashcode for Encryption.

Any help would be much appreciated!

Thanks,

PZ
