What is the Rails Encryption Gem and how do I use it?

The Rails Encryption Gem is a library that helps you encrypt sensitive data in your Rails applications. It provides a simple interface to encrypt and decrypt data, ensuring that sensitive information is stored securely.

Can you give me an example of how to implement it in my Rails app?

Sure! First, add the gem to your Gemfile: gem 'rails_encryption'. Then run bundle install. You can encrypt a string like this: encrypted_data = RailsEncryption.encrypt('my_secret_data'). To decrypt, use RailsEncryption.decrypt(encrypted_data).

Are there any best practices I should follow when using this gem?

Yes, always ensure that you keep your encryption keys secure and rotate them regularly. Also, avoid encrypting large amounts of data, as it can impact performance.

What types of data should I consider encrypting?

You should consider encrypting any sensitive information, such as user passwords, personal identification numbers, and financial data.
