PHP CC Encryption script needed

The end game is to create the string that goes in the XML Tag <din:EncryptedCard>, which can be found in two of the SOAP requests: AddCardTransaction and CommitPendingTicketWithCard. We are most likely going to be using AddCardTransaction.

The string inside of the tag must be in the form <encrypted key=\"ENCRYPTED_SYMETRIC_KEY\">ENCRYPTED_CARD</encrypted>

An example request looks like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/" xmlns:din="http://schemas.datacontract.org/2004/07/Dinerware.API.v01">







<din:EncryptedCard><encrypted key="UMk9IvmMmdwXakF82yUFGanuP4NUWehk9sZ/jGbsYVR7doWou+5rgeAgFKJTpCcOsbKSDj01aPpE9kP54O/Q5w==">Rw7wBMNoIedWyizn+qwH/7BFQuN1C6H5f8MYsJCrqKiaBPRmUtmec1VWFbri+R7GYpsuwmaQVjmXbfoavwYum+E5sZc1gQyVuETqDuauNSqizmY74UWX3brsxl6GpGrTxZKlLr9MIGzKaiKmGS+1MbIA9hKr/RHUMCEcLpqHdY/OU1Rj7kmdfPMtanFqU9Z57cA0LkKljhxIE2eKuDVk/1nF+w5845cPcpRTMqBklfIkHY0LuuOtOn6EaMms1y0o0uqE14YOQMyUDX+fWsfo17JGNDzxX2ytxF+YXgvZt6jlmG98Ym+1IkadSsK7HrYBfAseopvQD44=</encrypted></din:EncryptedCard>











The Encryption to output the string above works as follows:

Get PublicKey (in xml format: <RSAKeyValue><Modulus>oQFacRxwZ2goA5U2UbEDt0e2pjPF2SrO8nJ0vz+h70BQ5yc1XaIB3KwPS8Klsojd/UXgbuZbEJ/RxHNrRUtgIQ==</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>)

Get CVV, cardNum, expMonth, expYear, avrZip (card info)

Create string with card info like so:

<Card xmlns=\"[url removed, login to view]\" xmlns:i=\"[url removed, login to view]\"><CVV>CVV</CVV><CardNumber>cardNum</CardNumber><ExpMonth>expMonth</ExpMonth><ExpYear>expYear</ExpYear><AvrZip>avrZip</AvrZip></Card>

Generate a random IV

Generate a random Key

Use TripleDes with the Key and IV to encrypt the cardInfoString

Convert this to a Base64 String

Add Key and IV (in that order) to a 32 byte buffer

Encrypt this buffer with RSA using the obtained PublicKey

Convert the encrypted key to a Base64 string

Format a string with the encrypted card and symmetric key as mentioned above.

This for a restaurant POS system we are interfacing with.
