Hi expert, please help.
    I have try using code as follow, it encrypt well in my laptop, but after i upload to shard hosting envelopment. encrypt fail shown as follow.

System.Configuration.ConfigurationErrorsException: An error occurred loading a configuration file: Access to the path 'C:\Domains\domainname.com.my\httpdocs\8kgs3u4_.tmp' is denied. (C:\Domains\domainname.com.my\httpdocs\web.config) ---> System.UnauthorizedAccessException: Access to the path 'C:\Domains\domainname.com.my\httpdocs\8kgs3u4_.tmp' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access) at System.CodeDom.Compiler.TempFileCollection.EnsureTempNameCreated() at System.CodeDom.Compiler.TempFileCollection.AddExtension(String fileExtension, Boolean keepFile) at System.CodeDom.Compiler.TempFileCollection.AddExtension(String fileExtension) at System.Configuration.Internal.WriteFileContext..ctor(String filename, String templateFilename) at System.Configuration.Internal.InternalConfigHost.StaticOpenStreamForWrite(String streamName, String templateStreamName, Object& writeContext, Boolean assertPermissions) at System.Configuration.Internal.InternalConfigHost.System.Configuration.Internal.IInternalConfigHost.OpenStreamForWrite(String streamName, String templateStreamName, Object& writeContext, Boolean assertPermissions) at System.Configuration.Internal.InternalConfigHost.System.Configuration.Internal.IInternalConfigHost.OpenStreamForWrite(String streamName, String templateStreamName, Object& writeContext) at System.Configuration.Internal.DelegatingConfigHost.OpenStreamForWrite(String streamName, String templateStreamName, Object& writeContext) at System.Configuration.UpdateConfigHost.OpenStreamForWrite(String streamName, String templateStreamName, Object& writeContext) at System.Configuration.MgmtConfigurationRecord.SaveAs(String filename, ConfigurationSaveMode saveMode, Boolean forceUpdateAll) --- End of inner exception stack trace --- at System.Configuration.MgmtConfigurationRecord.SaveAs(String filename, ConfigurationSaveMode saveMode, Boolean forceUpdateAll) at System.Configuration.Configuration.SaveAsImpl(String filename, ConfigurationSaveMode saveMode, Boolean forceSaveAll) at System.Configuration.Configuration.Save() at test.EncryptConfig(Boolean bEncrypt)

I think the problem is show when the config.save is execute.
if i miss something or i there a way to get what appSettings.SectionInformation.ProtectSection("DataProtectionConfigurationProvider") have encrypt to show on label, so i can copy and paste it myself.

if can not be done, if there any way i can place it on my app_code by inherit ConfigurationSection or something to hide it from hacker. experts pls help.

Try
            Dim config As Configuration = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath)
            Dim appSettings As ConfigurationSection = config.GetSection("connectionStrings")
            If bEncrypt Then
                appSettings.SectionInformation.ProtectSection("DataProtectionConfigurationProvider")
 
                
                'appSettings.SectionInformation.ProtectSection("RSAProtectedConfigurationProvider")
 
                config.Save()
            End If
