eCryptfs is a cryptographic filesystem encrypting each file individually. To install ecryptfs add the following to environment.systemPackages:
{ pkgs, ... }: {
environment.systemPackages = with pkgs; [
ecryptfs
];
}
man ecryptfs-migrate-home describes how to encrypt your home folder. The TL;DR is that you need to: log out, log in as root, modprobe ecryptfs if needed, kill all processes that still access the home folder you want to migrate (check with lsof /home/YOURUSERNAME), wait for it to finish, then run ecryptfs-migrate-home -u YOURUSERNAME, then log in as your migrated user before rebooting.
To automatically mount your private folder on login with PAM, add this to your config:
{
security.pam.enableEcryptfs = true;
}
Don't forget to also load the ecryptfs kernel module on boot as well in this case:
{
boot.kernelModules = ["ecryptfs"];
}
