How do I set up attr_encrypted in my Rails application?

To set up attr_encrypted, first add the gem to your Gemfile: gem 'attr_encrypted'. Then run bundle install.

What do I need to do after installing the gem?

After installing, you need to configure the attributes you want to encrypt in your model. For example: attr_encrypted :email, key: 'a secret key'.

Can I use a different encryption key for each attribute?

Yes, you can specify different keys for each attribute by providing a unique key for each attr_encrypted declaration.

Is there a way to test if the encryption is working?

You can test it by creating a record, saving it, and then checking the database to see if the attribute is encrypted.
