Create and Mount an Encrypted Filesystem Using eCryptFS
In this lab you will create an encrypted directory using eCryptfs. Next, you will "mount" the directory in order to access files stored there. You are working as a System Administrator at a large financial institution and have been tasked with creating an encrypted directory using eCryptfs on a user's workstation running SUSE Linux Enterprise Server 15. You will need to log into the remote workstation and complete the following tasks to accomplish this: 1. Confirm the kernel module. 2. Install ecryptfs packages. 3. Add a passphrase to kernel keyring. 4. Create directories. 5. Mount the filesystem.

Challenge
Add Passphrase to Kernel Keyring
Add a passphrase to kernel keyring. Be sure to save the key signature, as it will be required when mounting the filesystem:
$ ecryptfs-add-passphrase $ export KSIG=

Challenge
Create Directories
For encrypted data:
$ mkdir secret-enc
For decrypted data:
$ mkdir secret

Challenge
Mount the Filesystem
Confirm the environment variable
$KSIG
was properly set fromecryptfs-add-passphrase
in previous step:$ echo $KSIG $ sudo mount -i -t ecryptfs secret-enc/ secret/ -o ecryptfs_sig=$KSIG,ecryptfs_fnek_sig=$KSIG,ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_unlink_sigs
