Hashing is a form of encryption used for swapping data between integrated data management systems. Eloqua's hashing identifier can apply and identify two types of hashes in order to anonymously trade email mail and phone number information with an external data source. The functionality uniquely identifies contacts with SHA256 and MD5 hashes, creates hashed equivalents of currently existing contact field information, and allows you to map these details to other systems without sending any Personal Identifiable Information (PII).

Once the hashing identifier is enabled, all contacts in your Eloqua database that have values in their Email Address, Business Phone, and Mobile Phone contact fields will then have hashed equivalents of those fields and their respective values:
- SHA256 Hashed Email
- SHA256 Hashed Mobile Phone
- SHA256 Hashed Business Phone
- MD5 Hashed Email
- MD5 Hashed Mobile Phone
- MD5 Hashed Business Phone
Hashed fields are automatically created and applied to contacts only with information in their non-hashed equivalents. For example, if a contact's Email Address is provided, but not their Business Phone or Mobile Phone, then only the SHA256 Hashed Email and MD5 Hashed Email are created and populated for that contact. If and when a contact's record are updated in any of the email or phone fields, their hashed equivalents are then updated as well.
In essence, the hashing identifier allows you to use an anonymous identifier in order to map your contact information to other systems (where you are using a CRM Integration, Oracle Data Cloud, or any other data source).
