本文實例講述了Python使用PyCrypto實現AES加密功能。分享給大家供大家參考，具體如下：

#!/usr/bin/env pythonfrom Crypto.Cipher import AESimport base64import os# the block size for the cipher object; must be 16, 24, or 32 for AESBLOCK_SIZE = 32# the character used for padding--with a block cipher such as AES, the value# you encrypt must be a multiple of BLOCK_SIZE in length. This character is# used to ensure that your value is always a multiple of BLOCK_SIZEPADDING = '{'# one-liner to sufficiently pad the text to be encryptedpad = lambda s: s + (BLOCK_SIZE - len(s) % BLOCK_SIZE) * PADDING# one-liners to encrypt/encode and decrypt/decode a string# encrypt with AES, encode with base64EncodeAES = lambda c, s: base64.b64encode(c.encrypt(pad(s)))DecodeAES = lambda c, e: c.decrypt(base64.b64decode(e)).rstrip(PADDING)# generate a random secret keysecret = os.urandom(BLOCK_SIZE)# create a cipher object using the random secretcipher = AES.new(secret)# encode a stringencoded = EncodeAES(cipher, 'password')print 'Encrypted string:', encoded# decode the encoded stringdecoded = DecodeAES(cipher, encoded)print 'Decrypted string:', decoded
