在Ruby中模仿AES_ENCRYPT和AES_DECRYPT函数

require 'openssl'
require 'base64'

def aes_encrypt(data, key)
  cipher = OpenSSL::Cipher.new('AES-128-ECB')
  cipher.encrypt
  cipher.key = key
  encrypted_data = cipher.update(data) + cipher.final
  Base64.encode64(encrypted_data)
end

def aes_decrypt(encrypted_data, key)
  cipher = OpenSSL::Cipher.new('AES-128-ECB')
  cipher.decrypt
  cipher.key = key
  encrypted_data = Base64.decode64(encrypted_data)
  cipher.update(encrypted_data) + cipher.final
end

data = 'Hello, world!'
key = '1234567890123456'

encrypted_data = aes_encrypt(data, key)
puts "Encrypted data: #{encrypted_data}"

decrypted_data = aes_decrypt(encrypted_data, key)
puts "Decrypted data: #{decrypted_data}"
