You will need different encryption and a key that you can share with the third party . The encryption function for the crypt string are internal to adobe and it would not be possible for the third part to decrypt the cryptId.
Would it be possible to use this functionality to send to a third party site?
We are sending a customers account number to a partner site in order to redeem a promotion, but if we use the escapeURL and crypt string the partner site may need the key to decypher. Is this possible or do we need to use soemthing else to encrypt the account number?
