"Giga password Generat0r". It has 23 differents modes for generating almost everything, including hexadecimal and personnal charset. The script is using the crunch generator, which makes it really fast to generate. The script is still in dev, I will add more modes later so that it will cover all the possibilities, including special chars and blank spaces.
The script is still in french yet, I will translate it when I will find some time.
