Diceware passwords should allow for minimal password rules

[coro1404]

Hi

I like diceware Passwords (Passphrase) but many sites enforce rules like "at least a number" or "at least one special character" so it would be nice if Passphrases would allow for adding minimal password rules to be appended or mixed into the passphrase.

Hey there. How would you like it to be? I can think of two solutions: one is giving the option to add a number at the end of the passphrase, and the second is the option to replace specific characters with numbers (e.g., A with 4).

I would suggest giving the option "at least one number" random position or first/last position
and "at least one special char of collection [...]" at random position or at first/last position - also I would suggest Capitalizing the words or using capital letters at random. I made a python script to emphasize my suggestions:

./dice.py
Enter the number of words for the password (default: 4): 6
Enter the separator between words (default: '-'):
Enter special characters (default: '!"§$%&/()=?`´#+-'): #
Enter the number of attempts per second (default: 1000000):

Estimated Time to Crack: 737869762948382.12 seconds (~8540159293.38 days / ~23397696.69 years)
