Can we bring Hashed Email address to original form in AEP data prep

[Nikhil719]

If source has hash Email address , can we bring it to original form in case we have hash  key in data flow data prep. I can see a lot of option to convert into hash value.

Hi @Nikhil719 

Could you elaborate the use case because I am not sure to understand the topic? have you got in mind People Based Destination type of scenario for instance?

Thanks

No, you cannot decrypt using data prep. Depending on the algorithm used, it would be a one-way hash. The data prep has functions to encrypt or hash the raw values into hashed values.
