KeePassXC 2.7.12 drops leading zero bytes of the P-256 x and y coordinates, so about one key in 128 failed registration. p256_point now left-pads 1 to 32 bytes and still rejects empty, oversized, out-of-field and off-curve points. KeePassXC also refuses passkeys on http://localhost until its Allow using localhost with passkeys option is on; the passkey page now says where to tick it. The zero-led test key search is capped at 4096 tries.
