Suggestion: Document the cryptosystem used to encrypt notes in the database.

[virtadpt]

As far as I can tell, Plainpad's app/Models/Note.php module uses Laravel's lluminate\Support\Facades\Crypt class. Some research suggests that the Crypt module implements AES-128 and AES-256, though I haven't found anything definitive about this, nor have I found the cipher mode that it implements (ECB (I hope not)? OFB? CBC?) It would be very helpful to know for sure what was used and how to come up with a threat model for Plainpad.

At https://alextselegidis.com/get/plainpad would be good, because that's the first place folks are likely to look (or google). A comment in the source code would also be helpful, because technical users are likely to go grepping through the files looking for hints as to what is used (as I did).
