Can a bitcoin private key have multiple public keys?

— When you own cryptocurrencies, what you really own is a “private key.” As it provides access to your cryptocurrencies, it should remain private. — You can have one or multiple public keys associated to every private key. — It’s possible to recover the public key if you own the private key.

How do I generate a public key from a private key in Bitcoin?

A public key is derived from a private key. To derive the public key you need an Elliptic Curve, Bitcoin chose to use secp256k1. 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.

Is it possible to hack a bitcoin private key?

Bitcoin users are assigned private keys, which allows access to their bitcoins. Hackers can infiltrate wallets and steal bitcoins if they know a user’s private key.

Can you find private key with public key?

No, there is no known efficient method to find an RSA private key from public key, ciphertext and plaintext, including when no padding is used and e=3. The best known method is factoring the public modulus, which then trivially allows to find a working private key.

Can I generate multiple public key from private key?

1 Answer. In practice and with respect to security, no, mathematically, yes. If you have a private key (N, D), there is algebraically an infinite number of solutions to the equation 1 = E*D (mod Phi(N)).

Can public keys be the same?

Just like a pair of identical house keys are interchangeable, a pair of identical public-private key pairs are interchangeable.

Can private keys hack?

Yes, it’s just a file protecting other secrets. If the OS of the system holding the private key is compromised then the key can be compromised. This is why keys are usually encrypted, requiring not only the key but a password as well (two factors, something you have + something you know).

How many private keys can I have?

A private key is a 256-bit number. This means that it is represented in binary in 256 numbers of 0 or 1. In total, this means there are a total of (almost) 2^256 combinations of private keys.
