How does Rails attr_encrypted handle decryption?
An example of an AI chatbot conversation about Rails attr_encrypted decryption.
Can you explain how Rails attr_encrypted handles decryption?
Sure! Rails attr_encrypted uses a symmetric encryption algorithm to encrypt and decrypt attributes. When you save an object, it encrypts the specified attributes, and when you retrieve it, it automatically decrypts them for you.
What encryption algorithm does it use?
By default, it uses AES-256-CBC for encryption, which is a strong and widely used symmetric encryption algorithm.
Is it possible to customize the encryption key?
Yes, you can customize the encryption key by specifying it in the model. This allows you to use different keys for different attributes or models.
Are there any security considerations I should be aware of?
Absolutely! Always ensure your encryption keys are stored securely and consider using environment variables to manage them. Also, keep your Rails version updated to benefit from the latest security patches.
