Possible Identity namespace for an email address

[mdajaz]

I have email address coming as hashed. I need to check with client/vendor what algorithm has been used to encrypt at source. Considering it is SHA256 encoded, I assume that I can use the Emails (SHA256, lowercased) OOTB ID NS for my use case. Please confirm.

If in case, it is encoded using a different algo what are the possible options and considerations before ingesting into AEP?

Thanks.

Hi @mdajaz  - yes, you are right. You are good to use the Emails (SHA256, lowercased) namespace for the pre hased email address from the source. 
Thank you,
Jay.
