BASE64Encoder，BASE64Decoder加密后再解密不成功(base解密32)
[java]中的加密和解密代码： pw 明文密码 pw2 数据库中的密码 String pw2已经解决了用JSP解决传递结果给ASP，死麻烦 告诉你一个简单的方法,你
import base64，zlib
’‘’解密base64编码‘’‘
a=base64.b64decode('解码内容')
’‘’解密zlib编码‘’‘
b=zlib.decompress('解码内容‘)
base64编码，不能算加密码，因为没有密钥。就是说谁都可以解码。
至于你说的不能解码，只能猜测是你的解码算法不正确。
百度百科上有关于base64的详细解释，应该对你有帮助。
解密出来后，还是有点乱，不过人可读了，你可以自己处理一下。

你用错了环境。
base64_encode和base64_decode是用来对 “网址” 中存在的特殊字符进行转码和解码，保证传输过程的正确性。和urlencode和urldecode类似。
在php里就属于url处理的函数。
其实Base64的加密和解密的算法不是很复杂，首先是定义自己64位的密钥，64个字符是固定，但是顺序是可以随自己的设计而变化。例如：
char[] BaseTable=new char[64]{
'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',
'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z',
'0','1','2','3','4','5','6','7','8','9','+','/'};
接下来，在加密的时候就是对于需要加密的每个字符，通过一定的算法，转换成上面64字符的一种；而在解密的时候则是把64字符中任意一个字符反算出加密前的字符。对于每个字符的操作有很多方法，这里就不一一介绍了。需要注意的是“=”字符，在Base64加密算法中，是很重要的，它是起到补零作用。
