EncryptedFields Mongoose-encrypt

EncryptedFields is a library that enables encrypting specific fields within a Mongoose model. This can be especially useful when dealing with sensitive data that should not be visible in plain text.

The library works by adding a layer of encryption to the fields specified within the model schema. When data is saved to the database, the specified fields are encrypted using a secret key that is stored securely outside of the database.

To use EncryptedFields, simply install the npm package:

npm i mongoose-encrypt

Then, require it in your code:

const encryptedFields = require('mongoose-encrypt');

Next, define a schema for your model, and specify which fields should be encrypted:

const userSchema = new mongoose.Schema({
  name: String,
  email: encryptedFields.encryptionProxy(String),
  password: encryptedFields.encryptionProxy(String),
});

The encryptionProxy method tells EncryptedFields to encrypt the field before saving it to the database.

Finally, when creating a new document for your model, simply assign values to the fields as usual:

const user = new User({
  name: 'John Doe',
  email: 'johndoe@example.com',
  password: 'password123',
});

user.save();

EncryptedFields will automatically encrypt the specified fields before saving them to the database.

Overall, EncryptedFields is a powerful and easy-to-use library that can help ensure sensitive data remains secure in your Mongoose MongoDB environment.
