# pwm

pwm very simply generates reasonably secure passwords. That's it; that's
all it does.

Passwords are chosen from the set of all upper-case letters except I and
O, all lower-case letters except l, and the digits 2 through 9. 0 and O
are not used to avoid confusion with each other. I, l, and 1 are not
used for the same reason.

Starting with version 1.1.0, passwords are guaranteed to contain at
least one upper-case letter, one lower-case letter, and one number.

## Usage

```ruby
require 'pwm'
Pwm.password(length)
```

The default length is 16. The minimum length is 8. Specifying a length
less than 8 will raise `Pwm::TooShortException`.

You can also call pwm from the command line:

```bash
$ pwm
h6ECtbDZPnRddHV7
$ echo $?
0
$ pwm 8
XdWod8f8
$ echo $?
0
$ pwm 4
length must be >= 8
$ echo $?
1
```
