Suppression lists are used on Campaigns and Sources to reject specific email addresses that you do not wish to send to your Marketing Automation or CRM system. Since Suppression lists contain Personal Identifiable Information (PII), the Demand Acceleration Platform allows you to upload lists that contain MD5 hashed values.
| Hashing Suppression lists in the Demand Acceleration Platform is optional. If you prefer not to hash the values in your Suppression list, refer to Suppression Lists. |

What is hashing?
Hashing is the process of using functions or algorithms to transform given values into values that are not easily readable or decodable, with the intention of protecting sensitive information.
How is hashing used in the Demand Acceleration Platform?
The Demand Acceleration Platform allows you to upload Suppression lists that contain MD5 hashed values in order to protect Personal Identifiable Information (PII) and ensure hashed values are properly compared during lead processing.
The Demand Acceleration Platform supports the use of MD5 hashing. MD5 is a hash function that produces a 128-bit hash value.
Consider the following:
| Plain Text Value | MD5 hash value |

Hashing your Suppression list
You can transform the plain text email values in your Suppression list into MD5 hash values by using:
- A trusted online MD5 generator.
- A custom Microsoft Excel Macro that you have created or acquired from a third party.
- A custom Google Sheets script that you have created or acquired from a third party.
