1. 最简单的方法是用base64:
复制代码 代码如下: import base64
s1 = base64.encodestring('hello world') s2 = base64.decodestring(s1) print s1,s2
# aGVsbG8gd29ybGQ=n # hello world
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
复制代码 代码如下: 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: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

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:
复制代码 代码如下: 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,'n',s2
# HGKGDGDGAGPCIHAGNHDGLG # hello world
