教你使用python获得字符串的md5值

  #!/usr/bin/env python    
    # -*- coding: cp936 -*-    
    import hashlib    
    
   def get_md5_value(src):    
       myMd5 = hashlib.md5()    
        myMd5.update(src)    
        myMd5_Digest = myMd5.hexdigest()    
        return myMd5_Digest    
   
    def get_sha1_value(src):    
        mySha1 = hashlib.sha1()    
        mySha1.update(src)    
        mySha1_Digest = mySha1.hexdigest()    
        return mySha1_Digest    
    
    if __name__== '__main__':    
        src = 'aaa'    
        result_md5_value=get_md5_value(src)    
        result_sha1_value=get_sha1_value(src)    
        print 'source string: ', src    
        print 'MD5: ', result_md5_value    
        print 'SHA1: ', result_sha1_value
