Lab: Quality Attributes and NFRs

[GMOkeefe]

Non-functional requirements:

• Neither passwords nor messages should be readable to someone with access to the database. Quality Attributes:
• Confidentiality
• Integrity

We intend to address this requirement by hashing passwords and encrypting messages. Dart includes several algorithms that can be used to encrypt/hash data, and sending that data using Google Firebase's methods, then storing the encrypted data. This will prevent even us from reading messages and passwords, even though we have full access to the database.

Ok, and also make sure you support https requests (not only http) so the messages/data between your nodes are exchange also through SSL encryption.
