今天重新做这个测试，发现limodou的方法有小问题：
windows下如果到脚本所在目录执行脚本
c:\Python24\python.exe script1.py
用os.path.dirname(sys.argv[0])获得的结果是''

argv[0]必须要用os.path.abspath()扩展成全路径，才能用os.path.dirname()取得
正确的脚本所在路径。

为什么我只找到了 cyrpt,md5,sha
现在经常用的des,,rsa,,aes,twofish,tea 等等,都没有找到..郁闷......

You'd better to use google more efficiently.

Google://"python crypto"

Python Cryptography Toolkit

The Toolkit is a collection of cryptographic algorithms and protocols,
implemented for use from Python. The current release is 2.0.1. Among
the contents of the package:

    * Hash functions: MD2, MD4, RIPEMD, SHA256.
    * Block encryption algorithms: AES, ARC2, Blowfish, CAST, DES,
Triple-DES, IDEA, RC5.
    * Stream encryption algorithms: ARC4, simple XOR.
    * Public-key algorithms: RSA, DSA, ElGamal, qNEW.
    * Protocols: All-or-nothing transforms, chaffing/winnowing.
    * Miscellaneous: RFC1751 module for converting 128-key keys into a
set of English words, primality testing.
    * Some demo programs (currently all quite old and outdated).

这个包里的加密和hash算法比较全的，可以试一下
