I believe that stock nginx does not include a way to do that.

What kind of corruption is the checksum intended to protect against?

The answer to that might help determine a suitable design for a solution
for you.

If it is acceptable to be outside nginx, you could have something that
post-processed the logs to add whatever marks you want.

Or maybe you could write nginx logs to a named pipe, and have another
process do whatever you want before writing to "real" disk.

Good luck with it,
