The signing nonce and the private key are drawn from makerandom. Because the high bit is always set, the result is not uniform: its top bit is fixed, producing insecure values.\"\n\nAn attacker who collects a modest number of signatures under an affected key, together with the public key, can recover the private key with a lattice attack.\n\nKeys used to sign with an affected version should be considered compromised and new keys should be generated."
