MD5，sha1的加密：Python 2.7

import hashlib
import os

def getmd5andsha1(filepath):
    if os.path.isfile(filepath):
        file_txt = open(filepath, 'rb').read()
    else:
        file_txt = filepath
    m = hashlib.md5(file_txt)
    mm = hashlib.sha1(file_txt)
    return m.hexdigest(), mm.hexdigest()

if __name__ == '__main__':
    s = raw_input('input file path or a string:')
    md5_str, shal_str = getmd5andsha1(s)
    print 'md5:', md5_str.upper()
    print 'sha1:', shal_str.upper()
    raw_input('press <Enter> to exit....')
