47.3 Using vi to Encrypt Single Files
The disadvantage of using encrypted partitions is that while the partition is mounted,
at least
root
can access the data. To prevent this, vi can be used in encrypted mode.
Use
vi -x filename
to edit a new file. vi prompts you to set a password, after
which it encrypts the content of the file. Whenever you access this file, vi requests the
correct password.
For even more security, you can place the encrypted text file in an encrypted partition.
This is recommended because the encryption used in vi is not very strong.
