Tokenization/De-identify Respondents' Emails - Server-side vs Client-side

Hi, I have a quick questions about how to tokenize/de-identify emails that respondents enter in my survey.

As a part of a multi-survey project, I need to create a survey that asks for a respondent's email and then tokenize it using a one-way function where the email will be converted to a random token in the first entry, and then in follow-up surveys, anytime the same email is entered, the same token is created (so I can link all different responses from the same person).

I already have built the tokenization function. However, I am unsure how to implement it in Qualtrics so that it runs on the server-side rather than on the client-side. Is that possible?

Thanks
