New Maintainer Needed
We are actively seeking a new maintainer for this gem! As we no longer use MongoDB as part of our platform, we aren't using the gem for ourselves. As MongoDB and Mongoid continually change, we want to make sure our gem keeps up.
If you're interested, please contact us! Thanks
A library for storing encrypted data in Mongo using Mongoid. We looked at a few alternatives, but wanted something that stored the values securely and unobtrusively.
Mongoid 3 supports custom types that need to only provide a simple interface - allowing us to extend core Ruby types to secure any type while providing a clean interface for developers.
Queries encrypt data before searching the database, so equality matches work automatically.
- Mongoid 5+
- Rails 4+
- Ruby 2.0+
- "Bring your own" encryption, see below
Mongoid 3, Mongoid 4 and Rails 3.2 are supported in version 1.x of this gem.
```ruby gem 'mongoid-encrypted-fields' ```
Configure the cipher to be used for encrypting field values:
GibberishCipher can be found in examples - uses the Gibberish gem:
Mongoid::EncryptedFields.cipher = Gibberish.new(ENV['MY_PASSWORD'], ENV['MY_SALT'])
Use encrypted types for fields in your models:
class Person include Mongoid::Document field :name, type: String field :ssn, type: Mongoid::EncryptedString end
The field getter returns the unencrypted value:
person = Person.new(ssn: '123456789') person.ssn # => '123456789'
The encrypted value is accessible with the "encrypted" attribute
person.ssn.encrypted # => <encrypted string> # It can also be accessed using the hash syntax supported by Mongoid person[:ssn] # => <encrypted string>
Finding a model by an encrypted field works automatically (equality only):
Person.where(ssn: '123456789').count() # ssn is encrypted before querying the database
- Single cipher for all encrypted fields
- Currently can encrypt these Mongoid types
- The uniqueness validator for encrypted fields should always be set to case-sensitive. Encrypted fields cannot support a case-insensitive match.
- Storing Encrypted Data in MongoDB
- Transparently Adding Encrypted Fields to a Rails App using Mongoid
