I got this code from Dave Barnes.
HSBC PHP CPI Integration Without Installing Software
All you need are:
* Your StorefrontId – this is your 8 digit ID, this will need to be prefixed with your 2-letter country code and have the 3-letter currency code appended to the end. E.G. UK12345678GBP
* Your encryption key this is a 32 character BASE64 encoded string unique to you.
* MHASH & MCRYPT available to PHP.
* SSL up and running on your server, HSBC will reject any requests that don’t come from an SSL connection.
* The class below to generate the hash (HSBC::GenerateHash()) from an array.
Code:
