"Credit Card Number Encryption
-----------------------------------------------------------------------------------------
If you want to secure your customers' credit card numbers, then you need this
contribution. As a online store owner, the increasing issues of securing
customers' online data is at its highest ever. This is my little contribution
to the cause.
During the past few months of reviewing and testing various encryption methods
contributed to the forum at osCommerce web site. I believe this contribution
will and should help a lot of osCommerce Users.

Below is MD5-based block cypher (MDC-like), which works in 128bit CFB mode.
It is very useful to encrypt secret data before transfer it over the network.
$iv_len -- initialization vector's length.
-PLEASE READ-IMPORTANT INFO ABOUT FUNCTIONS FOUND IN EN_DE_CRYPT.PHP------------------------
functions:
md5_encrypt($plain_text, $password, $iv_len = 16)
-and-
md5_decrypt($enc_text, $password, $iv_len = 16)
JTH Computer Systems notes and warnings:
If you pass a value to the $iv_len please remember the value or store it somewhere,
else you will not be able to decrypt the information. I suggest just using the default
value of 16.
The same goes for the variable $password, its value should not change after first use.

MUST READ!!!!
1) VERY IMPORTANT -- PLEASE -- PLEASE -- MAKE A BACKUP OF CODING AND DATA --
2) The INCLUDES FOLDER contains A ORIGINAL osCommerce layout of the CONFIGURE.PHP with additional
lines required for the encryption process. Be careful not to overwrite you vaild copy of this
file.
3) If you are just installing a new copy of osCommerce 2.2ms2-051113, then you can just copy
the changed files directly to your folder. Note: Do not Copy the CONFIGURE.PHP.
