QA:Testcase cryptsetup

Description

This test case ensures the correct functioning of cryptsetup, which is a utility used for setting up encrypted storage using the Device Mapper. The associated cryptsetup-libs provides the necessary libraries for cryptsetup.

Setup

1. Install cryptsetup and cryptsetup-libs: sudo dnf install cryptsetup cryptsetup-libs.
2. Create a blank file for testing: dd if=/dev/zero of=~/testcrypt bs=1M count=10.

How to test

1. Create a loopback device: sudo losetup -f ~/testcrypt.
2. Find the associated loopback device: losetup -j ~/testcrypt (note the loop device name for next steps).
3. Format the loopback device as a LUKS device: sudo cryptsetup luksFormat /dev/loopX (replace loopX with your loop device name).
4. Open the LUKS device: sudo cryptsetup luksOpen /dev/loopX mycrypt.
5. Check that a /dev/mapper/mycrypt device now exists.
6. Close the LUKS device: sudo cryptsetup luksClose mycrypt.

Expected Results

1. The loopback device should be successfully created without any errors.
2. The LUKS format command should prompt for a passphrase and complete without errors.
3. After opening, the /dev/mapper/mycrypt device should be present.
4. After closing, the /dev/mapper/mycrypt device should be removed.

Optional

For extended testing:

1. Try opening the LUKS device with an incorrect passphrase.
2. Test various cryptsetup commands and options.
3. Examine manual pages for more commands and utilities: e.g., man cryptsetup.
