RSA加密前端JS加密,后端asp.net解密,报异常
参考引用:http://www.ohdave.com/rsa/的JS加密库
前端JS加密代码:
function GetChangeStr()
{ debugger; var pwdStr = document.getElementById("txtPassWordStr").value; var uidStr= $("#<%=txtUserStr.ClientID%>").val(); if (!pwdStr || pwdStr.length == 0 || !uidStr || uidStr.length==0) { return false; } var keyE = "<%=PubRsaKeyE%>"; var keyM = "<%=PubRsaKeyM%>"; setMaxDigits(131); var key = new RSAKeyPair(keyE, "", keyM); var pwdRtn = encryptedString(key, pwdStr); var uidRtn = encryptedString(key, uidStr); $("#<%=txtPassword.ClientID%>").val(pwdRtn); $("#<%=txtUser.ClientID%>").val(uidRtn); }
后台解密代码:
try { RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)Cache.Get("privateKey"); byte[] result = rsa.Decrypt(HexStringToBytes(password), false); password = Encoding.UTF8.GetString(result); result = rsa.Decrypt(HexStringToBytes(userName), false); userName = Encoding.UTF8.GetString(result); } catch (Exception ex) { ShowMessage("身份验证失败!", "您登陆的帐号或密码错误!",""); return; }
发现在某些研发环境时会报“参数错误”异常。但在其它项目或服务器环境是正常的。
没有找到原因,不明原理啊!!
仅此做个记录。
