急急急!我需要编码与解码函数,加解密也行

[yuesongboy]

我在javascript中加密一段字符串,然后在服务器端代码中解密这个字符串

[孟子E章]

你这样问是不行的。客户端怎么加密的？

[yuesongboy]

我需要在客户端javascript调用javascript加密方法加密字符串,然后用服务器代码解密字符串,

谢谢

URL编码: bodyEncode.value = encodeURI(document.all.keyword.value)

URL解码: body.value = decodeURI(bodyEncode.value)

---------
你是问这个？

[cpp2017]

是要加密还是编码?

[yuesongboy]

加密编码都行啊,

[amao110]

Dim md5Hasher As New MD5CryptoServiceProvider
Dim hashedDataBytes As Byte()
Dim encoder As New UTF8Encoding
hashedDataBytes = md5Hasher.ComputeHash(encoder.GetBytes(TextBox2.Text))

[yuesongboy]

客户端javascript函数加密

服务器端代码函数解密

[yuesongboy]

高手去哪儿了???

[hertcloud]

javascript的escape函数进行转义

.cs


HttpUtility.UrlDecode()

[nmcfwhl1]

其实没有必要加密的。加密是可以。但是它会增加系统的不稳定。因为IE在解析的时候会理解错你加密后的代码

[yuesongboy]

@hertcloud(·￡孙子兵法￡·)
我不能用你的方法,不能达到我的要求,如果只要对字符串处理就行了,编码加密还是什么无所谓
然后在服务器端还原就可以了.

[cpp2017]

<script type="text/javascript" > function String.prototype.xor(key) //异或操作，也就是通用的对称加密、解密操作 { var result = ""; for (var i=0; i<this.length; i++) result += String.fromCharCode(this.charCodeAt(i)^key.charCodeAt(i%key.length)); return result; } var str = "test"; alert(str.xor("2")) </script>

[cpp2017]

protected void Page_Load(object sender, EventArgs e) { Response.Write(this.xor("FWAF", "2")); } protected string xor(string str,string sKey) { string res = ""; for (int i = 0; i < str.Length; i++) { res += ((char)(((int) str.Substring(i, 1).ToCharArray()[0]) ^ ((int) sKey.Substring(i % sKey.Length).ToCharArray()[0]))).ToString(); } return res; }

[yuesongboy]

怎么少了最后两个字符串?
