I have been reading more about private keys and don't fully understand. Apps or sites which create passphrases e.g 24 words that are used to create a private key. How on earth is this secure? Won't those be effectively brain wallets suspectivale to dictionary attacks?

well considering they use like 1000 possible words in the seed list and there are only 24 letters in the alphabet and 10 numbers you do the math idiot

Dash has an option to add your own words to the seed. I just trow in a bunch of meme words and words of my own language written in slang and all that no one can possibly ever dictionary that.

Anything that isn't bitcoin, specifically wallet.dat on cold storage, has risk. However how realistic is it that a 24 word electrum seed created in cold storage gets bruteforced? do the math.

Can someone answer this

On Ethereum there are 2 options for creating a private key.

a) wordpharse
b) the long private key itself
For Bitcoin (BTC BCH AND BSV)

ARE there SIMILAR to ETH 2 ways or

Is it just the 24 wordpharse


Thank you

ITT brainlets
first off, don't choose the phrase yourself, a computer is better at coming up with random shit.
Second, your phrase doesn't generate a private key, but is used as a seed to generate infinite keys.
Third, don't use a website to generate a phrase or keys to anything

Listen gramps this might be a bit over your head

>> No.12558432

>>12558353
the word phrase is just a generator seed for the long private key, so it's only a mnemonic for the key itself, same for bitcoin and pretty much every coin out there

True dat u can possibly leverage rng to cut down the number of addresses to check.
But otherwise there is no algo other than brute force, which is extremely inefficient.
Tbh, it is much easier to hunt for weak spots in privacy. Eg, phishing, keylogfers etx

after applying a Public key, the Private key has to be applied in order to unencrypt it. Viceversa, applying the Private makes it encrypted until someone can apply the corresponding Public.
to decrypt, you need to apply *both* the Private and Public key, no matter the order.

if I want to encrypt Something and be sure you're the only one who can decrypt it, I'll apply your Public key only. It's public, everyone knows it, but since you're the only one knowing your Private key, you'll be the only one decrypting my Something

Viceversa, if you want to sign Anything and be sure I'll be the one able to unencrypt and verify it was actually you to ship it, you will apply your Private key and my Public key. Thus, to verify it, your Public key and my Private key will be required. Your Public is -indeed- public, but my Private is not.

there's absolutely nothing wrong with using a brainwallet if you use a strong method for creating entropy for the passphrase. use diceware and casino dice.

probability is the only thing guaranteeing that the address doesn't exist already.
If you feel lucky, try this: https://www.bitaddress.org
you might end up generating binance's wallet.
