Title: Tool to create Private / Public Key from random words? Post by: spazzdla on October 21, 2017, 01:40:40 PM Something where you pick like 16, 36.. 400? words and it gives you a combo ?

You can create a brainwallet in https://www.bitaddress.org/ (https://www.bitaddress.org/) by selecting the tab "brain wallet"It will create your address and private key from words or phrases. I would not recommend it though. Brainwallets are insecure. Many of them have been hacked. You might think you are selecting random words, but they probably are not as random as you think, and that helps attaker in cracking your key. Title: Re: Tool to create Private / Public Key from random words? Post by: ranochigo on October 21, 2017, 02:34:08 PM Brainwallet is incredibly insecure. Unless you can be certain that no one would ever, I mean ever, guess your passphrase, then you can use it, just don't store too much.
If you'd like, you can try using this: https://keybase.io/warp/. It is safer* than regular brainwallets due to the different technique in generating the brainwallet and also having it salted. *It is by no means anywhere as safe as generating an address from your desktop wallet.

Post by: coinableS on October 23, 2017, 01:43:05 AM Best to learn to do it yourself so you know you can re-create it in 10 years, you won't have to rely on bitaddress or whoever to still be around.
Probably one of the easiest things to do in python, even for non-programmers. Download python 3.X Install, make sure to check to include IDLE and adding python pip to PATH Open command prompt and type Code: pip install bitcoin Code: pip install pybitcointools Now open up Python IDLE, file -> new include the bitcoin package Code: from bitcoin import * Create a variable that includes your random words Code: myVariable = "taco public free convenient garbage gumball" Then run it through a sha256 hash Code: priv = sha256(myVariable) Now you can encode it into a WIF private key Code: privwif = encode_privkey(priv, 'wif') Then to get the corresponding address, encode the public key then encode to base58 Code: privpub = privtopub(priv) Code: from bitcoin import * Then save the file, and run it (F5).

No, sha256 is a one-way hash function. To get the words from just a private key, sha256 would have to be broken and bitcoin would need to change it's base layer crypto algorithm.

Problem being, while not broken, sha256 is rather easily brute forced nowadays, which is why it's also not recommended for storing passwords in databases anymore. Alternatively you could use a more work intensive hashing algorithm such as bcrypt, scrypt or Argon2. However I personally am not familiar enough with Python to recommend any libraries that provide these hashing functions. Title: Re: Tool to create Private / Public Key from random words? Post by: AltCoinProject on November 04, 2017, 08:34:53 AM You want to make a brute force attack to random addresses. You can create random addresses without words with python.
from bitcoin import * for addr in range(1000): // 1000 results shown each priv = sha256(random_key()) pub = privtopub(priv) addr = pubtoaddr(pub) print (addr) print (priv) If you are lucky, you can get an address with priv key in nect 1000 years, which have balanced non-zero.
