How to encrypt log4net log files

c#, log4net

Solution

I'm assuming you want to encrypt the log's output. In that case you will need to write your own Appender which can handle the encryption. I would suggest figuring out what output mechanism you intend to use without encryption (i.e. FileAppender, EventLogAppender, etc.), and then extend that Appender and override the functionality that actually writes out the output.

The reference documentation on the appenders can be found here.

For instance, extend the FileAppender with an EncryptedFileAppender and override/implement the members you need to in order to hook into the file writing.

Alternatively, you could extend from IAppender and create an appender completely from scratch. That would give you more control, but might require more work if all you're trying to do is encrypt your payload.
