Encrypt data at rest
- SQLite database only
  - SQLCipher / @journeyapps/sqlcipher
  - SQLite3 Multiple Ciphers / better-sqlite3-multiple-ciphers
  - No: It’s cumbersome because it requires us to change the SQLite that we use (which happens to be Node.js’s SQLite, so we probably want to keep that simple)
- Directory
  - gocryptfs
    - FUSE
    - Replaces EncFS and ecryptfs
No: Could interact badly with SQLite, because it needs advanced filesystem features including locking, fsync() and so forth

We use two tools to measure the performance of slow pages:

0x: Profile the application and generate flame graphs.
autocannon: Load test (send lots of requests) and measure response time (which autocannon calls “latency”) & throughput.

Here’s a step-by-step guide of how to use these tools in Courselore:

Run the application normally.

Note: Don’t use a custom HOSTNAME, because autocannon may not recognize the self-signed certificate generated by Caddy.
