⚙ Configuration

Config file

Note: If the configuration file does not exist at startup, the user will be prompted to guided through a generation prompt.

Location

The configuration file is located in:

Config Options

• color: This allows for colored output to the terminal. This is recommended. Note: color is set to false, icons will be disabled.
• editor: This is the command that will be used to render an editor to the user for note input.
• banner: blackout, without any arguments, defaults to interactive mode. banner enables a banner message on startup.
• auto_copy: Enable/disable generated passwords and passphrases to be automatically copied to the clipboard when generated.
• icons: Enable/disable icons. Note: this requires nerdfonts.
• autobackup: Enable/disable auto-backups of blackout data when a note/totp url is added or edited.

Here is an example configuration.

color = true
editor = "vim"
banner = true
auto_copy = false
icons = true
autobackup = true

Wordlist

On startup, the file https://raw.githubusercontent.com/bitcoin/bips/master/bip-0039/english.txt will be downloaded to the config directory stated above and named wordlist.txt. This is a list of 2048 words used for wallet seed phrase generation.

When directed to generate a passphrase, blackout will choose the given number of words randomly from this list and capitalize each chosen word with a probability of 0.5. Thus, by default, there are $n^{4096}$ possibilities, where $n$ is the number words to be generated in the passphrase.

Any words added to this file are able to be chosen by the passphrase generator. Entries MUST be on a newline (no comma separated lists, no space separated lists).

🛡 ️Security

Encryption

blackout uses SQLCipher which is a fork of SQLite that adds 256 bit AES encryption of database files and other security features like:

• on-the-fly encryption
• tamper detection
• memory sanitization
• strong key derivation
• algorithms provided by the peer reviewed OpenSSL crypto library
