Encrypting binary (and relay) logs in MySQL


Keeping your data secure is an important task of the DBA. We protect our servers, encrypt filesystems and/or datafiles. But what about log files? And especially log files that contain actual data such as the MySQL binary or relay logs. These are technically called log files but they contain the actual data going through your MySQL systems for replication purposes. I will describe how you can enable and use them and also, in case of disaster, how you can recover your encrypted binary logs so you can use them for point in time recovery.
