Using a secure account§
Accounts containing trust secrets need special care.
Storage§
Full disk encryption§
encrypted partition§
You need package cryptsetup-bin.
Install it if not done already.
Physically connect the disk (if removable) and mount first encrypted disk and then its partition inside:
sudo cryptdisks_start mysecrets
sudo mount /mnt/mysecrets
When done working with encrypted data, unmount first partition and then disk:
sudo umount /mnt/mysecrets
sudo cryptdisks_stop mysecrets
