Networking work often sits alongside this. Our IP subnet calculator works out ranges and masks from CIDR notation, and the bandwidth calculator estimates transfer time and monthly data use.
Frequently asked questions
Is it safe to generate a password on a website?
This one is — the password is generated entirely in your browser using JavaScript and never transmitted anywhere. That said, generating sensitive passwords offline or with a dedicated password manager is always a reasonable extra precaution.
What does 'entropy' mean here?
It measures how many possible passwords could be generated with your chosen settings, expressed in bits — each additional bit doubles the search space an attacker would need to brute-force, so higher entropy means exponentially harder to guess.
Why exclude ambiguous characters?
Characters like I, l, 1, O, and 0 can look nearly identical in some fonts — excluding them makes a generated password easier to read and manually retype correctly, at a small cost to the total character pool.
