Card entropy changed significantly from v0.4.3 to v0.5.0. A full deck without replacement generates 225 bits of entropy (21 words). A full deck with replacement generates 232 bits of entropy (21 words). In that case you might choose to use your own source of entropy.Ĭard entropy has been implemented assuming cards are replaced, not drawn one after another. If cryptographic randomness isn't available in your browser, this page will show a warning and the generate button will not work. The built in random generator can generally be trusted more than your own intuition about randomness. The random mnemonic generator on this page uses aĬryptographically secure random number generator. Steganography may be beneficial when storing the mnemonic. Instead of storing entropy, store the mnemonic generated from the entropy. Storing entropy (such as keeping a deck of cards in a specific shuffled order) is unreliable compared to storing a mnemonic. Random enough for the needs of this tool. Keyboard mashing, or anything you think is random, because chances are overwhelming it isn't
