title: RollingEncryptedFileAppender for logback?
body: <p>I've searched the documentation located in the <a href="http://logback.qos.ch/manual/appenders.html#serverSocketAppender" rel="nofollow">logback manual</a> for an appender that will encrypt the log messages to a local file. The SSLServerSocketAppender seems to be exactly what I want except for the part that sends the log messages to a remote server. I just want the logs encrypted to a local file using an SSL key. I know I could write my own implementation, but I'd rather reuse an already existing one if possible. So far I haven't been able to find one.</p>
  
  <p>Is there an Appender, or an encoder that could be used in conjunction with a RollingFileAppender, that allows encrypting (with an SSL key) the log messages to the local file system rather than to a remote server?</p>
