.NET加密配置文件connectionStrings节点

具体的可以参考petshop源码程序。

加密前:

  <connectionStrings>
    <add name="SQLProfileConnString" connectionString="server=(local);user id=mspetshop;password=pass@word1;database=MSPetShop4Profile;min pool size=4;max pool size=4;packet size=3072"
    providerName="System.Data.SqlClient" />
    <add name="SQLMembershipConnString" connectionString="server=(local);user id=mspetshop;password=pass@word1;database=MSPetShop4Services;min pool size=4;max pool size=4;packet size=3072"

EncryptWebConfig.bat加密批处理代码:

@echo off
