- kinghajj 6y agoBitcoin wallets don't use RSA, but ECDSA.
- bhouston 6y agoI was referring to the possibility of man in the middle attacks on Bitcoin applications.
- postalrat 6y agoOnce people figure out the math to break bitcoin then they can transfer bitcoin from any address. I don't know why people don't bring this up more often. It will likely happen long before quantum computers make it possible.
- kinghajj 6y agoBecause, simply, it's not true. I'm curious though what attack vector you're thinking of, especially one that's not related to quantum computers. Are you worried that the ECDSA public-key cryptosystem employed by Bitcoin will be broken, such that the private keys could somehow get derived easily from the public ones? If so, that still wouldn't let an attacker "transfer bitcoin from any address," since the addresses themselves are hashes of the public keys. So people would have to stop re-using addresses to receive bitcoin multiple times, since once an address has been the sender in a transaction, and its public key revealed, it would become vulnerable.
