Intro text here ...

A more ambitions version of me would take a crack at adding this functionality to Hugo and opening a PR.

```sh
openssl rand -hex -out secret.key 32
```

---

```sh
openssl \
  aes-256-cbc \
  -in secretfile.txt \
  -out secretfile.txt.enc \
  -pass file:secret.key \
  -iter 1000000
```

---

```ruby
Dir.glob("content/**/*.{jpg,jpeg,png}").each do |path|
  `openssl aes-256-cbc -in #{path} -out #{path}.enc -pass file:secret.key -iter 1000000`
end
```

  `git filter-repo --invert-paths --force --path #{path}`
end
```

I'm 41 years old, and this stuff still gives me a buzz like it did when I was 14.
