- contextCan AI recover a wallet private key? The proof that is still missing: The 2019 study explains that reusing the same ECDSA nonce across signatures on two different message hashes under the same key permits algebraic recovery of the nonce and long-term secret key, while sufficiently short or correlated nonce values can permit lattice-based private-key recovery from multiple signatures without defeating the general elliptic-curve discrete logarithm problem.

- supportsCan AI recover a wallet private key? The proof that is still missing: ECDSA signing depends on properly generated per-signature nonces; RFC 6979 warns that even modest bias can lead to attacks and specifies deterministic nonce generation without changing keypair generation.
