将Java中的加密代码转换为Ruby

加密代码：

def aes(key,string)  cipher = OpenSSL::Cipher::Cipher.new("aes-128-cbc")  cipher.encrypt  cipher.padding = 1  cipher.key = hex_to_bin(Digest::SHA1.hexdigest('secret_key')[0..32])  cipher_text = cipher.update(string)  cipher_text << cipher.final  return bin_to_hex(cipher_text).upcaseend

解密代码：

def aes_decrypt(key, encrypted)  encrypted = hex_to_bin(encrypted.downcase)  cipher = OpenSSL::Cipher::Cipher.new("aes-128-cbc")  cipher.decrypt  cipher.padding = 1  cipher.key = hex_to_bin(Digest::SHA1.hexdigest('secret_key')[0..32])  d = cipher.update(encrypted)  d << cipher.finalend

hex_to_bin和bin_to_hex

def hex_to_bin(str)  [str].pack "H*"enddef bin_to_hex(s)  s.unpack('C*').map{ |b| "%02X" % b }.join('')end

在我的情况下，Java代码使用默认的初始化向量，因此我没有设置任何iv，此外，那里

hex_to_bin
