To ensure email addresses are formatted correctly for integration, they must be transformed into what format?

For integration processes, particularly when dealing with email addresses, it is crucial to maintain data integrity and support secure practices. Transforming email addresses into SHA256 format provides a way to hash the data. This is beneficial because hashing creates a fixed-length string, which helps to prevent the exposure of raw email addresses and enhances privacy by making it significantly harder to reverse engineer the original email address from the hash.

Using SHA256 allows organizations to process email addresses in a manner that supports security requirements while still enabling necessary functionalities, such as matching and integration across different systems without revealing sensitive personal information. This method balances the need for data usability with compliance and privacy considerations.

In contrast, converting email addresses to plain text format does not provide any level of security or data protection, while base64 encoding is primarily used for representing binary data in an ASCII string format and does not secure the information. Encryption format, while secure, may not be necessary in this case, as a hash function like SHA256 suffices for verifying and processing the email addresses without revealing them.
