# BetterPassphrase

**BetterPassphrase** is a Python library and CLI tool for generating *somewhat* secure, meaningful passphrases. It uses various parts of speech to construct grammatically correct and easy-to-remember phrases.

---

## Features

- **Customizable Length**: Generate passphrases with a specified number of words.
- **Custom Separators**: Use any character as a separator between words.
- **Capitalization Options**: Choose whether to capitalize the words in the passphrase.
- **Probability Calculation**: Get the uniqueness probability of the generated passphrase.
- **Verbose Output**: Optionally display detailed information about the generation process.
- **CLI Support**: Generate passphrases directly from the command line.
- **Multiple Phrases**: Generate multiple passphrases at once.
- **Output to File**: Save generated passphrases to a file.

---

## Installation

Install the package via [PyPI](https://pypi.org/project/BetterPassphrase):

```bash
pip install BetterPassphrase
```

---

## Usage

### Library Usage

Use the library in your Python code to generate passphrases programmatically:

```python
from betterpassphrase import generate_phrase

# Generate a passphrase
phrase = generate_phrase(length=6, sep="-", capitalize=True)

print(f"Generated passphrase: {phrase.passphrase}")
print(f"Word count: {phrase.word_count}")
print(f"Probability: {1 / phrase.one_of:.2e}")
```

### CLI Usage

After installing the package, you can use the `betterpassphrase` command directly from your terminal:

```bash
betterpassphrase --length 6 --sep "" --capitalize --verbosity 1
```

#### Options

| Option          | Short Flag | Description                                                   | Default |
| --------------- | ---------- | ------------------------------------------------------------- | ------- |
| `--length`      | `-l`       | Number of words in the passphrase                             | `6`     |
| `--sep`         | `-s`       | Separator to use between words                                | `-`     |
| `--capitalize`  | `-c`       | Capitalize the words                                          | `False` |
| `--output`      | `-o`       | Save passphrase to a file                                     | None    |
| `--num-phrases` | `-n`       | Number of passphrases to generate                             | `1`     |
| `--verbosity`   | `-v`       | Verbosity level: 0 (passphrase only), 1 (basic), 2 (detailed) | `0`     |

#### Example CLI Output

```bash
$ betterpassphrase --length 8 --sep "-"
Generated phrase: the-actor-and-the-subtle-dancer-played-wonderfully
Word count:       8
```

To generate a passphrase with capitalization and a custom separator:

```bash
$ betterpassphrase --length 8 --sep "=" --capitalize
Generated phrase: The=Actor=And=The=Subtle=Dancer=Played=Wonderfully
Word count:       8
```

To generate multiple passphrases:

```bash
$ betterpassphrase --length 4 --num-phrases 3
Generated phrase: curious-monkey-jumped-over
Generated phrase: silent-shadow-walked-alone
Generated phrase: sloppy-photographer-developed-timer
```

To write the passphrase(s) to a file:

```bash
$ betterpassphrase --length 8 --sep "-" --output passphrase.txt
Generated phrase: the-actor-and-the-subtle-dancer-played-wonderfully

$ cat passphrase.txt
the-actor-and-the-subtle-dancer-played-wonderfully
```

Verbose mode can provide additional details:

```bash
$ betterpassphrase --length 6 --verbosity 2
Generated phrase:       what-dirty-photographer-wrapped-which-stethoscope
Word count:             6
Wordlist Probability:   3.64e-14
Character Probability:  5.51e-63
Parts of speech:        determiner, adjective, subject_noun, verb, determiner, object_noun
```
