When Would I Use SHA256?

When adding to your Franchise Ninja Suppression Lists you can add the emails in a SHA format as well as standard email uploading. 

How Do I Turn My Emails Into SHA Format? 

If your software platform will not produce a SHA256 output, not to worry,  we've got you covered.

Our team has created an Excel sheet with an embedded function to hash a value to SHA256. Download the Zip Folder attachment in this article to securely turn your emails into the hash format.  To use the function, you would call it like this: 
=@SHA256Hash(A1)


Alert
When  you initially open the file, you will get a warning about an embedded code. You must accept the warning and click 'enable macros' if asked.


Info
Important note, since this would be a calculated field, this should be used to calculate the SHA256 column, then copy the SHA256 column and paste it by "Value" to another spreadsheet.
