What is SHA256 Encoding?
SHA256 encoding (Hash Algorithm/Hashing) is a set of cryptographic hash functions. Hashing is an encryption of data that has been transformed into a secure format that is unreadable, unless the recipient has a key.

When Would I Use SHA256?
When adding to your Visual Visitor 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:
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.
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.
