Dexios

Choosing a Key

Use a strong password, if you're planning to use an entered one.

dd can provide a suitable keyfile if you'd prefer a higher level of security:

dd if=/dev/urandom of=keyfile bs=1 count=4096 for a 4kb random keyfile

If you lose your file's key/keyfile, there is no recovering the encrypted data. This is not unique to Dexios - it's the nature of encryption as a whole.

Options for providing a key

You may provide keys in a few ways:

• -k for giving path to a keyfile
• --auto to tell Dexios to auto-generate a key
• The DEXIOS_KEY environment variable
• A user-provided password (this can be chosen by just running Dexios, and providing none of the above)
