Python加密模块有好几个,但无论是哪种加密方式都需要先导入相应的加密模块然后再使用模块对字符串加密。
先导入md5加密所需模块:
import hashlib
创建md5对象
m = hashlib.md5()
生成加密串,其中 password 是要加密的字符串
m.update('password')
获取加密串
psw = m.hexdigest()
输出
print psw
执行:
5f4dcc3b5aa765d61d8327deb882cf99
为了方便,我们可以写成函数,直接传入要加密的字符串调用即可
def md5(str):
import hashlib
m = hashlib.md5()
m.update(str)
return m.hexdigest()
调用:
str = md5('password')
如果传入的参数不是字符串会报错
str = md5(['a','b'])
报错:
Traceback (most recent call last):
File "D:\python\demo1\c.py", line 9, in
str = md5(['a','b'])
File "D:\python\demo1\c.py", line 5, in md5
m.update(str)
TypeError: must be string or buffer, not list
我们可以对传入的类型检测,避免报错
def md5(str):
import hashlib
import types
if type(str) is types.StringType:
m = hashlib.md5()
m.update(str)
return m.hexdigest()
else:
return ''
当我们传入的参数为字符串即可正确返回加密串,其他类型均返回空!

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
