If the ith byte of the hash is greater than or equal to 8, you convert the ith address's character to uppercase, otherwise you leave it lowercase. Note that it is easy to go from BitcoinSecret to private Key. To convert from an uncompressed public key to a compressed public key, you can omit the y value . We'll use this private key throughout the article to derive both a public key and the address for the Bitcoin wallet. I'm pretty sure those addresses are empty, but before I erase this old file, I would like to convert these different private key to public address to check if all is empty. To do sha256 with EVP_MD, just replace EVP_ripemd160 () with EVP_sha256 (), and update (input to EVP_MD) your input . Private Key. A good way is to take the sha256 checksum of the private key and append the last 8 bits of it to the private key, so you get 264 bits, which map to 24 words. Here is the resulting code: #!/usr/bin/env python ''' Creates BitCoin Wallet complaint credentials: - Public Key - Private Key - Private Key (Wallet Import Format) ''' import hashlib import base58 import ecdsa from ecdsa.keys import . Your public key is your private key multiplied by the generator point (which is a constant set in the secp256k1 standard), so it's a point on the curve. I would use an online service to check these addresses all at once (some allow control of up to 50 addresses). I developed these tools for Bitcoin users, I hope they are useful and help save time.
