@ -4,11 +4,11 @@ A tool for mounting encrypted partitions.
## Use case
I have encrypted partitions that I need to mount them from time to time.
I have encrypted partitions that I need to mount and unmount from time to time.
I use GPG to encrypt the decryption keys for each partition, save them as `${uuid}.key`

## Usage

mountpoint: /boot
```
Then when you run `xmnt boot`, the tool will decrypt `/dev/nvme0n1p2` and mount it on `/boot`.
Then when you run `xmnt boot`, the tool will look for encryption key according
to the UUID of `/dev/nvme0n1p2`, read the key, call `gpg --decrypt` to decrypt
the key when necessary, then use the key to open `/dev/nvme0n1p2`, and mount it
on `/boot`.
Directories for storing encryption keys are defined in
`$XDG_CONFIG_HOME/xmnt/xmnt.yml`. The tool will recursively search these
directories for keys.
You can also use it without defining presets. See `--help` for detailed usage.
## Supported partition types
- luks encrypted partitions (e.g. ext4)
- luks encrypted partitions (e.g. ext4). "plain" format is not supported.
- regular unencrypted partitions
- zfs datasets
