 ## About
 
-The backend hosts the breached passwords for use in the Private Set Intersection computation. The user sends a password and receives that password and the set of breached passwords both encrypted with secret key `b`. The backend uses [Crow](https://crowcpp.org/master/) for the REST API, [SQLite3](https://www.sqlite.org/index.html) for the breached password database, and [Libsodium](https://libsodium.gitbook.io/doc/) for the cryptography. The API has a single endpoint:
