Configure third party unsubscription link in AJO

Hi Team,

We have a third party hosted Landing page with which we want to configure unsubscribe.

To implement this we have implemented Subscription API call through Developer Console to update the preference of indivdual profile. To achieve this we have used the following document:

Email opt-out management | Adobe Journey Optimizer

There is a requirement to pass two encrypted parameters in the URL

1. params( which will contain encrypted payload data) and

2. Pid (Profile ID)

The challenge here is how to encrypt these values in runtime in AJO/AEP and pass it to individual user while sending email.
