python android aes

[ChenLi]

i use your aes jni in android project;
but i meet a problem;
android send the encrypt message to python server
but my python server can not decrypt the encrypt message ,
this is my python aes_utils
`class AESUtil:
__BLOCK_SIZE_16 = BLOCK_SIZE_16 = AES.block_size

@staticmethod
def encrypt(str, key):
    cipher = AES.new(key, AES.MODE_ECB)
    x = AESUtil.__BLOCK_SIZE_16 - (len(str) % AESUtil.__BLOCK_SIZE_16)
    if x != 0:
        str = str + chr(x) * x
    msg = cipher.encrypt(str)
    msg = base64.urlsafe_b64encode(msg).replace('=', '')
    return msg

@staticmethod
def decrypt(enStr, key):
    print ("---------->22")
    cipher = AES.new(key, AES.MODE_ECB)
    print ("---------->33  " + key)
    enStr += (len(enStr) % 4) * "="
    decryptByts = base64.urlsafe_b64decode(enStr)
    msg = cipher.decrypt(decryptByts)
    paddingLen = ord(msg[len(msg) - 1])
    return msg[0:-paddingLen]`

AES has a complex encryption, configuration items are more, so try to use the same code, android is java call C, the server can use python call C to achieve.

请直接说中文，我想表达的是既然C可以跨平台，何不服务端跟客户端用同一套代码，安卓是用java调用C，你服务端可以python调用C，IOS可以Objective-c调用C，这样子实现代码统一，几乎不会出现任何问题，而且维护成本很低。
