MurageKibicho / PrivateKey.c

Created July 25, 2025 11:46

Hacking a dormant bitcoin wallet involves finding the wallet’s private key. Owning a bitcoin is equivalent to knowing a wallet’s private key. The process can be summarized as: A private key generates a public key. The public key is hashed by SHA256 + RIPEMD. The hash is encoded in Base58. The encoded Base58 string is the wallet address. We wrote…
