Please refer to the software license for more detail. Using less than 2048 PBKDF2 iterations is insecure without strong optional BIP39 Passphrase. To access them with custom PBKDF2 iterations, use this file (or other) to compute your targeted BIP39 seed. However, as long as you back up your BIP39 seed there will not be risk to lost your fund. Increasing this parameter will increase security against brute force attack, but you will need to store this new parameter. Wallet software that implement BIP39 only use 2048 iterations as a norm. Please refer to this wikipedia article for more detail. What is PBKDF2 (Password Based Key Derivation Function 2) ? 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.
