如何使用Python进行Rijndael方式的加密解密？

Question

以下是使用PHP进行Rijndael方式加密的例子：

function encrypt($data) {
  return base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256 ,'oqufXQ(?bc=6_hR2I3sMZChDpb6dDlw4', $data , MCRYPT_MODE_CBC, utf8_encode('fOaiIOkD8*9Xeu_s4_bb87Ox_UG+D9GA')));
}

我曾找到这个代码，里面的答案的确可行，但如何自定义iv？（即utf8_encode('fOaiIOkD8*9Xeu_s4_bb87Ox_UG+D9GA')）
另，block_size、key_size和iv_size均需要为32（字节）。

编译mcrypt.c，GCC提示错误如下：

mcrypt.c: In function 'initmcrypt':
