note that here we do the lookup only on the domain name and only set the encoding parameters on creation. Shows this behavior:

```
$ pwm get -l 8 facebook.com
Enter your master password: 
y[ckHg&#
$ pwm get facebook.com
Enter your master password: 
y[ckHg&#
$ pwm get -l 16 facebook.com
Enter your master password: 
y[ckHg&#
```

This might be a bit counter-intuitive and need improving.
