PuTTY and embedders (f.i., filezilla) -- biased RNG with NIST P521/ecdsa-sha2-nistp521 signatures permits recovering private key

Simon Tatham reports: ECDSA signatures using 521-bit keys the NIST P521 curve, otherwise known as ecdsa-sha2-nistp521 were generated with biased random numbers. This permits an attacker in possession of a few dozen signatures to RECOVER THE PRIVATE KEY. Any 521-bit ECDSA private key that PuTTY or...
