Generate password with default length (4 words) and default separator (space).

echo Generator::generateEn();

// would output something like "laut welt ganze liter"
echo Generator::generateDe();

echo Generator::generateRuTranslit();

Each of above functions accepts length and separator paramenetrs.

echo HaiBrini\Password\Generator::generateEn(5, '-');

Advanced usage

Call static function Generator::generate to generate passwords from wordlists. Params

• wordlists - array of WordListInterface. If array is shorter then length, function would iterate from the beginning of array.
• lenght - password length in words. Default - 4
• separator - words separator. Default - ' '(space)

    [
        new HaiBrini\Password\WordList\En(), 
        new HaiBrini\Password\WordList\RuTranslit()
    ],
