字串CryptoJS前臺加密，pycrypto後臺解密（備份一下）

最近我想做一個前臺加密，後臺解密的功能，網上找了好久都不怎麼好用。本人也不瞭解加密演算法，只有自己摸索。
寫完記錄一下
——————————————————————
程式碼只是個例子，沒有前後臺互動
我用的是pycrypto需要安裝，我用的是pycrypto-2.6.1.tar.gz，
安裝pycrypto-2.6.1.tar.gz需要pyasn1-0.3.7.tar.gz
python 程式碼
from Crypto.Cipher import AES def cryptoDe(pwd): print "#######################" print pwd BS = AES.block_size pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS) unpad = lambda s : s[0:-ord(s[-1])] mode = AES.MODE_CBC cipher = AES.new('1234567890000000',mode,'1234567890000000') decrypted = unpad(cipher.decrypt(pwd.decode('hex'))) print decrypted print "#######################" return decrypted
前臺程式碼
我用的是CryptoJS v3.1.2外掛
