Creating unique URLs for customers using N/crypto module
I’m getting ready to send an email to customers containing a summary of purchases in the prior year. I’d like to include a simple way for customers to access a more detailed version of the report if they choose, without needing to log in. (Most business is done offline, majority of customers don’t have access to login)
The report is created/emailed by a Map/Reduce script.
My plan is to use the N/crypto module when creating each email to encrypt the customers internal id, and store it as a parameter in a link on the email. The link would be to a Suitelet having “Available Without Login” enabled.
On request to the Suitelet, the URL parameter would be decrypted followed by performing a search and rendering the results to a PDF template, which is then served to the user.
Is there anything I may be overlooking here? I have read that encrypting/decrypting with SS2.0 is a little more work because of generating the GUID and such, is it recommended to use a JS library to handle cryptography instead?
I personally think its a lot of work to hide an internal id number.
