🎲 Random Generator
Generate random bytes, passwords and passphrases.
How strong is it?
Everything comes from the browser’s cryptographic random generator (crypto.getRandomValues), with rejection sampling so every character or word is equally likely. Entropy is length × log₂(choices): 80 bits is strong for an online account, 128 bits is beyond any brute force. Passphrases use the 2048-word BIP39 English list, so each word adds 11 bits.
