SHA-256 an email address Link in Velocity

Hi,

I am working with Conversant to add in parameters, they have asked if hasing is possible with Marketo, as below - 

  • The dtm_email_hash parameter (dtm_email_hash={{lead.Email Address}}) should be encrypted using SHA256 hashing as that is personal information. Is this possible with market?

Is it possible to SHA256 Hashing an email address in an link?

Thanks,

Haroon

I assume your search found https://nation.marketo.com/community/product_and_support/blog/2018/07/17/sha-256-ing-an-email-address-in-velocity and you're wondering if it still works that simply?

Unfortunately, after June 2019 it's not that simple. It would now have to be written in "pure" Velocity, like my Base64 routinehttps://nation.marketo.com/community/product_and_support/blog/2019/10/13/base64-ing-a-string-in-velocity-without-using-reflection So the answer is: absolutely, it can be done by a skilled Velocity developer. But there's no built-in function for it.

Alternately, you could call a webhook-compatible service (not calling it at send time, but rather when the email address is created/changed) to compute the pre-SHA'd email address and store it in another field. For a slowly-changing field like the email this would work fine.

Thanks Sanford!

Is there any webhook-compatible service you know of? Would help me look into it a little more.

Yes... but Community Guidelines prohibit mentioning it.

If I were in your shoes I'd build it in Velocity, knowing it can be done. But obvs. that's easy for me to say.
