加密MachineKey
ASP.NET中设置MachineKey可以很轻松的实现SSO,可以在所有ASP.NET站点中添加如下配置:
<machineKey validationKey="XXXXXX" decryptionKey="XXX" validation="SHA1" />
validationKey可以为视图状态、身份验证Cookie、Session等重要的信息添加杂乱信息以防止重要信息被篡改。
为了防止validationKey和decryptionKey以明文的方式进行显示,可以使用ProtectSection方法对machineKey配置节进行加密。
1、在Web.config中添加原始的配置,如:
<machineKey validationKey="XXXXXX" decryptionKey="XXX" validation="SHA1" />
2、通过程序对system.web/machineKey节进行加密和解密
加密方式如下:
Configuration config = WebConfigurationManager.OpenWebConfiguration("/");
ConfigurationSection machineKeySection = config.GetSection("system.web/machineKey");
machineKeySection.SectionInformation.ProtectSection("RSAProtectedConfigurationProvider");
machineKeySection.SectionInformation.ForceSave = true;
config.Save();
解密方式如下:
Configuration config = WebConfigurationManager.OpenWebConfiguration("/");
ConfigurationSection machineKeySection = config.GetSection("system.web/machineKey");
machineKeySection.SectionInformation.UnprotectSection();
machineKeySection.SectionInformation.ForceSave = true;
3、通过程序加密就会得到类拟:
<machineKey configProtectionProvider="RsaProtectedConfigurationProvider">
<EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"
xmlns="http://www.w3.org/2001/04/xmlenc#">
<EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#tripledes-cbc" />

</EncryptedData>
</machineKey>
这样的配置,你只要把这段配置复制到各个需要SSO的站点的Web.config就可以了,系统在运行过程中会自动进行解密
如果想变回原来的明文显示可以执行解密的相反过程就行
注意:其中的OpenWebConfiguration("/");表示打开站点根目录下的web.config,其它情况可参考如下:
