How can we write/run the migration with sequelize-encrypted methods

[Edvinraj]

How to add encrypted fields to existing table when run the migration(sequelize-migration)? Because we have to pass key for encryption and define some enc_fields,vault in migration file. I'm struck with those..

Set your encrypted attributes as type Sequelize.BLOB

'use strict';
module.exports = {
  up: (queryInterface, Sequelize) => {
    return queryInterface.addColumn('users', 'encrypted', {
      type: Sequelize.BLOB
    });
  },
  down: (queryInterface, Sequelize) => {
    return queryInterface.removeColumn('users', 'encrypted');
  }
};
