How to do Credit card number encryption?
We are using web service to post a credit card details from our application(Ruby On Rails) to an ERP? When ever the details are submitted through application it says 'Invalid credit card number'.
We found the credit card number is encrypted as follows in ERP:- "`555555******4444|==SDS02D85D1AC31B3C4E389C8593EADA73DDE00000000BCC---##|1|4444`".
Can any one help us understand what encryption algorithm is being used here?

Thanks,
