json格式数据加密问题
求助,服务器这边通过php 返回的json串给手机客户端这边,在数据传递过程中 json数据需要加密。到底怎么来加密呢?不会就直接加密json串吧 这样肯定不行。
------解决方案--------------------
两边约定密钥,根据密钥加解密。
------解决方案--------------------
简单点,直接写死就行了。
json_encode得到字符串,对字符串加的偶数字节加噪声(比如异或某个1-127的整数),之后使用和客户端约定好的对称密钥解密就行了,对称密钥写死在服务端和客户端,免得让人不法人士看到。
要安全的话很明显客户端应该走Https 443端口请求这个json串,而不是你在应用层自己加密数据。
------解决方案--------------------
那你可以对加完密的数据字串进行二次处理,如加减乘除……,选取指定字符进行运算
------解决方案--------------------
两方约定密钥,Des加密可以,PHp加密,对端使用密码进行Des解密就搞定了
密文体直接用json串
