如何使用Python进行Rijndael方式的加密解密?

时间:2021-07-01 10:21:17 帮助过:5人阅读

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_sizekey_sizeiv_size均需要为32(字节)。


编译mcrypt.c,GCC提示错误如下:

mcrypt.c: In function 'initmcrypt':
mcrypt.c:1714:2: error: incompatible type for argument 1 of 'PyString_FromString
'
In file included from C:\Python27\include/Python.h:94:0,
                 from mcrypt.c:24:
C:\Python27\include/stringobject.h:63:24: note: expected 'const char *' but argu
ment is of type 'double'
error: command 'gcc' failed with exit status 1
