如何在Rails中使用AES-128-GCM加密？

gem 'openssl'

require 'openssl'

module Encryption
  def self.encrypt(data, key, iv)
    cipher = OpenSSL::Cipher.new('aes-128-gcm')
    cipher.encrypt
    cipher.key = key
    cipher.iv = iv

    encrypted = cipher.update(data) + cipher.final
    auth_tag = cipher.auth_tag

    [encrypted, auth_tag]
  end

  def self.decrypt(encrypted_data, auth_tag, key, iv)
    decipher = OpenSSL::Cipher.new('aes-128-gcm')
    decipher.decrypt
    decipher.key = key
    decipher.iv = iv
    decipher.auth_tag = auth_tag

    decipher.update(encrypted_data) + decipher.final
  end
end

class UsersController < ApplicationController
  include Encryption

  def encrypt_data
    data = 'Hello, World!'
    key = 'your_key'
    iv = 'your_iv'

    encrypted_data, auth_tag = Encryption.encrypt(data, key, iv)
    # 处理加密后的数据
  end

  def decrypt_data
    encrypted_data = 'your_encrypted_data'
    auth_tag = 'your_auth_tag'
    key = 'your_key'
    iv = 'your_iv'

    decrypted_data = Encryption.decrypt(encrypted_data, auth_tag, key, iv)
    # 处理解密后的数据
  end
end
