- You want to see Version 2 here. V1 is deprecated and less secure.
Check your LUKS containers and partitions.
- V1 can be upgraded to V2 easily most of the time with a single command. Read up on iterations too and check if yours are good enough for your purposes.
- Always have backups when performing dangerous operations on important data.
- Do your homework before starting. It's always good to have a better understanding of current encryption standards. You can learn from people who know what they are doing here:
