先上段代码，这个代码是转自网上

以UTF8的编码保存这个代码到/usr/lib/python2.7
In [1]: import jastmencrypt In [3]: jastmencrypt.encrypt(119,'mypassword') 加密 Out[3]: u'KBOAHAGBEAEAAAIBFADB' In [4]: jastmencrypt.decrypt(119,'KBOAHAGBEAEAAAIBFADB') 解密 Out[4]: u'mypassword'
我们在ipython中先加密好密码，然后拿到代码里，要使用的时候解密一下即可，这样可以很大程度上保证我们的密码安全。
