seqCryptor
This is a small module to encrypt specififc columns with seqeuelize. It's a little like https://www.npmjs.com/package/sequelize-encrypted but since seqeuelize-encrypted hasnt been updated for five years and we needed a typescript version, we deciced to create a new module.
It's just 80+ rows of code, so nothing fancy, but our goals was to create a module that we could use in procjects that need to encrypt data AFTER the project had grown a lot. So this is designed with the goal of chaning as little as possbile to the normal model definition in sequelize.
It currently only supports DataType.STRING
, DataType.JSONB
and DataType.JSON
.
How to use it
This is the most basic example:
// Create the encryptor with your secret key
const encryptor = seqEncryptor('YOUR_SUPER_SECRET_32_BYTES_KEY__');
const sequelize = new Sequelize({
dialect: 'sqlite',
storage: ':memory:',
define: {
timestamps: true,
},
logging: false,
});
class User extends Model {
public name!: string;
public guid!: string;
}
User.init({
guid: {
allowNull: false,
unique: true,
type: DataTypes.UUID,
defaultValue: DataTypes.UUIDV4,
},
name: encryptor({ // THIS IS THE ONLY DIFFERENCE. Together with the field below.
type: DataTypes.STRING,
field: 'name', // THIS IS REQUIRED. The initiation functions doens't have access to the name in the json,
// so we need to explicitly write it.
}),
}, {
sequelize,
paranoid: false,
});
await User.sync();
const user = await User.create({ name: 'bar' });
const rawUser = await User.findOne({ where: { guid: user.guid }, raw: true });
console.log(rawUser.name); // Will print an encrypted string
const loadedUser = await User.findOne({ where: { guid: user.guid } });
console.log(loadedUser.name); // Will print "bar"
How to test it
