The AEAD cipher literally means Authenticated Encryption and Associated Data. However, exaf-rs is not doing anything about the associated data part. It could be useful when creating an encrypted archive to attached unencrypted data. The point of AEAD is to ensure that both the cipher text and the AD have not been tampered with. A good example is patient medical records (encrypted) and their member identifier (plain text).
