Keeps missing =>

You can use CryptSetup on #Linux: (assuming `sudo` in front of each command)

```cryptsetup luksFormat /dev/mmcblk0

cryptsetup luksOpen /dev/mmcblk0 opt

ls -arlt /dev/mapper | tail
ls -l /dev/mapper/opt

mkfs -t ext4 /dev/mapper/opt```

Where we've named the encrypted drive `opt` and opened in the systems /opt directory, -t is type ext4 which works on Linux systems

```mount /dev/mapper/opt /opt

umount /opt
cryptsetup luksClose opt

ls -l /dev/mapper/opt

'no such file'```

That's not what I posted =>
All I see is #VeraCrypt. He's podcasting, you can listen with Android on https://fountain.fm/oi?code=ce25e6f91a , his podcast https://fountain.fm/show/m7qullz5GucrfjeqaB9l

You can use CryptSetup on #Linux: (assuming `sudo` in front of each command)

```
fdisk -l
```
Assuming `mmcblk0` is the sdcard:


`shred -v -n 1 /dev/mmcblk0`

where -v, verbose and -n, number of iterations

```cryptsetup luksFormat /dev/mmcblk0

cryptsetup luksOpen /dev/mmcblk0 opt

ls -arlt /dev/mapper | tail
ls -l /dev/mapper/opt

mkfs -t ext4 /dev/mapper/opt```

Where we've named the encrypted drive `opt` and opened in the systems /opt directory, -t is type ext4 which works on Linux systems

```mount /dev/mapper/opt /opt

umount /opt
cryptsetup luksClose opt

ls -l /dev/mapper/opt

'no such file'```
