No, there is not currently any such capability in rosbag2. However, you can always accomplish any arbitrary thing you want manually. Not sure if you're looking for encryption of entire messages or just output files, but

For message encoding - for example create your own "EncryptedMessage.msg" type, performing any operations you want to do, then writing these messages into the bag
For file encryption, write the bag file as normal, then encrypt the file with whatever tooling after it is closed

Thanks @emersonknapp. I'm writing the messages with a node built by following this tutorial

https://docs.ros.org/en/galactic/Tuto...

I guess in case I want to encode the messages I should do it before the serialization process. Thanks again
