title: Mask Passwords with Logback?
body: <p>We currently generically log all XML documents coming in and going out of our system, and some of them contain passwords in the clear. We would like to be able to configure the logback logger/appender that is doing this to do some pattern matching or similar and if it detects a password is present to replace it (with asterisks most likely). Note we don't want to filter out the log entry, we want to mask a portion of it. I would appreciate advice on how this would be done with logback. Thanks.</p>
