Python version of the Diceware method for generating secure passwords.

Usage

python diceware.py [OPTIONS]

By default, 6 words in lower case separated by spaces are generated. The script uses the Diceware method, which is considered secure but only if a password contains a minimum number of words for certain applications. Please read this website and its FAQ.

The script can also generate a sequence of random alphanumeric characters, which can be mixed with extra special characters, depending on the option.

Currently, only two languages are covered: en and pl.

As a side note, Password strength test is one of the tools to have a rough idea about how strong a passphrase is. While the application is neither perfect nor foolproof, as describer states, it still points out potential weak parts of a password.
