Witango-Talk: MD5 & Credit cards

[James Macfarlane]

Title: Message

Here is my implementation of generating MD5 security hash as a TCF call based on Anthony M. Humphries' Javascript sample. Included is the TAF to call the class file. Enjoy!

Tango's MD5 implementation is fine. I've already alerted the author of that page that he's missing Tango/Witango from it.

From the links on that page you can find a JavaScript implementation of MD5 and you can compare Witango's calculation of MD5 with the JavaScript implementation.

 

<@CIPHER> is the tag you want to use.

 

I found a bug in Witango's ENCODING=JavaScript a while ago while playing with MD5 and SHA1, the test suite is attached.

 

I very rarely store passwords for logins in the DB any more, I now store hashes of the passwords, so I have some experience with MD5.

 

What would you like to know?

We have a client who wants to add credit card validation to their site. The credit card agency expcets us to provide an "MD5" key with the checkout data. From what I've read MD5 is some sort of checksum and is used to detect someone hacking the form data we're submitting.

I've found a page with some MD5 implementations in different languages (http://userpages.umbc.edu/~mabzug1/cs/md5/md5.html) Tango not being one of them.

Has anyone worked with MD5 in Tango? Your expereinces would be apreciated.
