1. 最简单的方法是用base64:- import base64
- s1 = base64.encodestring('hello world')
- s2 = base64.decodestring(s1)
- print s1,s2
- # aGVsbG8gd29ybGQ=\n
- # hello world
复制代码 Note: 这是最简单的方法了,但是不够保险,因为如果别人拿到你的密文,也可以自己解密来得到明文
2. 第二种方法是使用win32com.client- import win32com.client
- def encrypt(key,content): # key:密钥,content:明文
- EncryptedData = win32com.client.Dispatch('CAPICOM.EncryptedData')
- EncryptedData.Algorithm.KeyLength = 5
- EncryptedData.Algorithm.Name = 2
- EncryptedData.SetSecret(key)
- EncryptedData.Content = content
- return EncryptedData.Encrypt()
- def decrypt(key,content): # key:密钥,content:密文
- EncryptedData = win32com.client.Dispatch('CAPICOM.EncryptedData')
- EncryptedData.Algorithm.KeyLength = 5
- EncryptedData.Algorithm.Name = 2
- EncryptedData.SetSecret(key)
- EncryptedData.Decrypt(content)
- str = EncryptedData.Content
- return str
- s1 = encrypt('lovebread', 'hello world')
- s2 = decrypt('lovebread', s1)
- print s1,s2
- # MGEGCSsGAQQBgjdYA6BUMFIGCisGAQQBgjdYAwGgRDBCAgMCAAECAmYBAgFABAgq
- # GpllWj9cswQQh/fnBUZ6ijwKDTH9DLZmBgQYmfaZ3VFyS/lq391oDtjlcRFGnXpx
- # lG7o
- # hello world
复制代码 Note: 这种方法也很方便,而且可以设置自己的密钥,比第一种方法更加安全,是加密解密的首选之策!
3. 还有就是自己写加密解密算法,比如:- def encrypt(key, s):
- b = bytearray(str(s).encode("gbk"))
- n = len(b) # 求出 b 的字节数
- c = bytearray(n*2)
- j = 0
- for i in range(0, n):
- b1 = b[i]
- b2 = b1 ^ key # b1 = b2^ key
- c1 = b2 % 16
- c2 = b2 // 16 # b2 = c2*16 + c1
- c1 = c1 + 65
- c2 = c2 + 65 # c1,c2都是0~15之间的数,加上65就变成了A-P 的字符的编码
- c[j] = c1
- c[j+1] = c2
- j = j+2
- return c.decode("gbk")
- def decrypt(key, s):
- c = bytearray(str(s).encode("gbk"))
- n = len(c) # 计算 b 的字节数
- if n % 2 != 0 :
- return ""
- n = n // 2
- b = bytearray(n)
- j = 0
- for i in range(0, n):
- c1 = c[j]
- c2 = c[j+1]
- j = j+2
- c1 = c1 - 65
- c2 = c2 - 65
- b2 = c2*16 + c1
- b1 = b2^ key
- b[i]= b1
- try:
- return b.decode("gbk")
- except:
- return "failed"
- key = 15
- s1 = encrypt(key, 'hello world')
- s2 = decrypt(key, s1)
- print s1,'\n',s2
- # HGKGDGDGAGPCIHAGNHDGLG
- # hello world
