Before:

```ruby
ActiveSupport::MessageVerifier.new(secret).inspect
"#<ActiveSupport::MessageVerifier:0x0000000104888038 ... @secret=\"\\xAF\\bFh]LV}q\\nl\\xB2U\\xB3 ... >"
ActiveSupport::KeyGenerator.new(secret).inspect
"#<ActiveSupport::KeyGenerator:0x0000000104888038 ... @secret=\"\\xAF\\bFh]LV}q\\nl\\xB2U\\xB3 ... >"
```

After:

```ruby
ActiveSupport::MessageVerifier::Aes256Gcm(secret).inspect
"#<ActiveSupport::MessageVerifier:0x0000000104888038>"
ActiveSupport::KeyGenerator::Aes256Gcm(secret).inspect
"#<ActiveSupport::KeyGenerator:0x0000000104888038>"
```
