I am trying to integrate the SagePay form integration onto a website. I have read the whole V3.00 documentation on the website/pdf as well as downloaded and installed the FORM integration kit/demo.

The demo works perfectly, but it's not what I am doing. There is no real info about how to use the FORM integration kit.

I have collected the details I need on a form and now have them ready to Encrypt for the CRYPT field on the form to send to SagePay. What function in the integration kit do I need?

Is there a proper basic user guide on there to show you how to use the integration kit?

<form method="POST" id="SagePayForm" action="*https://test.sagepay.com/gateway/service/vspform-register.vsp*">
<input type="hidden" name="VPSProtocol" value= "3.00">
<input type="hidden" name="TxType" value= "50.00">
<input type="hidden" name="Vendor" value= "*YOURVERNODID*">
<input type="hidden" name="Crypt" value= "THIS IS WHAT I NEED">
<input type="submit" value="continue to SagePay">

How do I go about getting, and decrypting the return CRYPT message too, to process and update a database etc?

I cannot find a good guide on how to go about doing this.

The V3.0 Documentation only defines the method of encryption (128 bit AES Encryption) that is used and doesn't provide the file or process which are being referenced in the kit.

I had to a little research and found this answer useful for encryption in another thread: Java Class for Encryption

Following are the summarized steps to be followed in encyprtion:

  1. Encrypt string using JAVA class
  2. Convert the encrypted string to hex-base( Base 16) text
  3. Now, convert this text to Upper case (All caps).
