Hello @Tang, Suzanne ,

There is NO hash function in ADF , but if you are using mapping dataflow you can use this .

Let me know how it goes.

Thanks

Hash calculation is also needed for some authentication token creations. E.g. https://lyyti.readme.io/docs/authentication-and-authorization

Hash calcucation should be also available on ADF expression level to generate authentication tokens for HTTP requests.

I I Implemented a Azure function to compute the checksum, stored in database and use it later in the data factory pipelines.
